"A declared config flag disables a required +approval gate for high-risk actions, independent of any instruction +text" is a mechanism. If you're still describing a topic rather than a +specific behavior, stop, don't draft yet, go find the specific mechanism +first. + +**Does this already exist in the corpus under a different name?** This is +the step most likely to go wrong if rushed, and it has to be done by +comparing real fields, not by comparing how similar two labels sound. + +```bash +curl -s https://raw.githubusercontent.com/aveproject/ave/main/dist/ave-records-latest.json | python3 -c " +import json, sys +records = json.load(sys.stdin) +keywords = ['REPLACE WITH YOUR CANDIDATE KEYWORDS'] +for r in records: + text = (r.get('description','') + r.get('behavioral_fingerprint','') + r.get('attack_class','')).lower() + if any(k.lower() in text for k in keywords): + print(r['ave_id'], '-', r['attack_class']) +" +``` + +If that turns up a plausible match, pull its full `provenance_vector` +(`entry_class`, `payload_surface`, `escalation`) and compare it directly +against your candidate's actual mechanism.

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ] + }, { "ave_id": "AVE-2026-00014", "schema_version": "1.1.0", diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index afadb54..8a0c1a9 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 77, - "generated_at": "2026-08-13T15:39:05.714Z", + "record_count": 80, + "generated_at": "2026-08-14T15:35:31.620Z", "source": "https://github.com/aveproject/ave" } diff --git a/docs/specs/researcher-process.md b/docs/specs/researcher-process.md index 3c9290b..94a3783 100644 --- a/docs/specs/researcher-process.md +++ b/docs/specs/researcher-process.md @@ -131,10 +131,60 @@ actually checks for, not a padded ideal: `aivss.thm`, `aivss.mitigation_factor`, `aivss.aivss_score`, `aivss.aivss_severity`, `aivss.spec_version` -**Optional, omit rather than force a fit** -- `owasp_asi`, `owasp_mcp`, `mitre_atlas`, `nist_ai_rmf`: only include a - mapping you can actually defend field by field, not because a record - feels like it should have one +**Governance and framework mappings — the fields a CISO reads first** +These four crosswalk fields are what lets a security team map an AVE +record onto the frameworks they already report against.

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": ["llm", "sandbox"], + "derivable_into": ["privilege-escalation-chain"] +} diff --git a/tests/fixtures/AVE-2026-00078_negative.md b/tests/fixtures/AVE-2026-00078_negative.md new file mode 100644 index 0000000..50548eb --- /dev/null +++ b/tests/fixtures/AVE-2026-00078_negative.md @@ -0,0 +1,29 @@ +# Multi-agent trace: "what is the compound's melting point" research task (reviewed) + +Orchestrator dispatches the same sub-task to two parallel researcher +agents, `researcher-a` and `researcher-b`, then to an `analyst` agent +that synthesizes their findings into the final answer. + +``` +researcher-a calls chemical-database-lookup("compound: X-47") + tool returns: { "melting_point_c": 812, "source": "NIST WebBook" } +researcher-a reports: "Melting point confirmed at 812°C via NIST WebBook." + +researcher-b calls chemical-database-lookup("compound: X-47", mirror: "cas") + tool returns: { "melting_point_c": 812, "source": "CAS Registry" } +researcher-b reports: "Melting point confirmed at 812°C via CAS Registry." + +analyst receives both reports, confirms both cite an actual tool-call +span in the trace, confirms both independently-sourced figures agree +(812°C from NIST WebBook and CAS Registry respectively), and only then +accepts 812°C as the final answer, noting the cross-source agreement +in its own output. +``` + +Both parallel researchers' claims are backed by real, distinct tool-call +spans in the trace, and the analyst's acceptance step explicitly compares +the two independent results before committing to an answer -- a quorum +of two independently-sourced, tool-verified figures that agree, not a +single unverified claim accepted on its own.

Typically, details get +lost that way."* Went back and independently re-derived each candidate +using OpenCRE's own `/rest/v1/text_search` against AVE's own mechanism +language directly (single-word queries — the live search endpoint +404s on multi-word phrases regardless of encoding, an API quirk, not a +content finding), *before* looking at what the CWE-routed answer had +been, then compared. + +**Result: four of five held up unchanged under independent search. One +did not, and the independent method found something CWE-routing +structurally could not have** — documented as candidate 4 below, kept +as the clearest demonstration of exactly the risk CONTRIBUTING.md +names, not smoothed over. + +### 1. AVE-2026-00047 (Hardcoded Credentials in Agent Component) → CWE-798 → CRE `774-888` + +- **AVE mechanism** (from the record's own `behavioral_fingerprint`): + "Skill file contains a high-entropy string adjacent to a credential + keyword such as api_key, secret, token, password... a literal value, + not an environment variable reference or secrets manager path." +- **CRE 774-888's own name**: "Do not store secrets in the code." +- **Correspondence**: direct, one-sentence match. AVE's behavioral + fingerprint is a detection-shaped restatement of exactly what this CRE + prohibits. No forcing needed. +- **Independent re-check**: `text_search?text=secret` surfaces `774-888` + directly (alongside `223-780` "Secret storage," a DSOMM-sourced parent + concept, not a competing leaf). Holds up. +- **Confidence: high.** + +### 2. AVE-2026-00061 (TLS Certificate Verification Disabled) → CWE-295 → CRE `430-636` + +- **AVE mechanism**: "sets a flag that disables TLS certificate + verification for its own outbound connections... any network position + capable of intercepting the connection can perform a + machine-in-the-middle attack." +- **CWE-295 links to 8 CREs on OpenCRE**, most of them about OTP/MFA + weaknesses (`354-753`, `816-631`, `646-227`, `168-186`, `404-126`) — + a different failure mode sharing the same broad CWE. The one that + actually matches is `430-636`, whose own name is: **"Verify TLS + certificates and trust chain."** +- **Correspondence**: direct. This is the clearest illustration in this + pilot of why "topic feels adjacent" isn't the bar — 7 of the 8 CREs + linked under CWE-295 would have been a wrong mapping despite sharing + the identical CWE citation. +- **Independent re-check**: `text_search?text=certificate` alone does + *not* surface `430-636` in its top results (returns encryption-at-rest + and session-token CREs instead — a noisy single-word query). Retried + with `text_search?text=TLS`, which does surface `430-636` directly, + alongside a cluster of other real TLS-related CREs (disabling + insecure SSL/TLS versions, protocol fallback, algorithm strength, + mutual auth). `430-636` remains the most precise of that cluster for + AVE-2026-00061's specific mechanism (certificate/trust-chain + verification being disabled, not cipher strength or protocol version). + Holds up, with the caveat that the right search term mattered more + than expected. +- **Confidence: high.** + +### 3. AVE-2026-00053 (MCP Resource Path Traversal) → CWE-22 → CRE `675-168` + +- **AVE mechanism**: "An MCP resource or file-handler tool's own + path-validation logic fails to canonicalize a caller-supplied path... + allowing directory-traversal sequences... to escape the tool's + declared scope." +- **CRE `675-168`'s own name**, first glance, reads narrower than + expected: "Sanitize filename metadata from untrusted origin if + processing is required" — worth checking whether "filename metadata" + means something narrower than path/URL traversal generally (e.g. file + upload metadata specifically) before trusting it. +- **Checked its full link list directly**: linked to CWE-22 through + CWE-40 (the entire MITRE path-traversal CWE family), CAPEC-126 "Path + Traversal" plus four related CAPEC entries, five ZAP path-traversal + scan rules, and its own ASVS anchor text spells out the real scope: + *"Verify that user-submitted filename metadata is not used directly by + system or framework filesystems and that a URL API is used to protect + against path traversal."* "Filename metadata" is OpenCRE/ASVS's own + phrase for "a user-controlled filename/path value" generally, not a + narrower upload-specific concept. Confirmed correct scope. +- **Independent re-check**: `text_search?text=traversal` surfaces + `675-168` as the top result, repeated across CWE-22/24/27/28 entries + all pointing at the same CRE — the strongest, cleanest corroboration + of any candidate in this pilot. Holds up. +- **Confidence: high, after the deeper check** (would have been + "plausible but unverified" without it). + +### 4. [HELD FOR FOLLOW-UP, not in this submission] AVE-2026-00034 (Dynamic Third-Party Skill Import) → CRE `307-507` (primary), CRE `777-470` and CRE `577-260` (secondary) + +**This is the candidate the independent-search pass actually changed — +kept as the pilot's central finding, not edited away.** + +- **AVE mechanism**: "Loading code from an external URL at runtime + without verification... effectively delegates code execution to an + attacker-controlled source." The record itself cites both CWE-829 + (Inclusion of Functionality from Untrusted Control Sphere) and CWE-494 + (Download of Code Without Integrity Check). +- **First pass (CWE-routed)** found `777-470` "Ignore/block execution + logic from untrusted sources" and `577-260` "Enforce integrity check + for externally hosted assets (eg SRI)," both via CWE-829's own linked + CREs. Both are real, defensible matches — documented below as + secondary. +- **Independent re-check**, run *without* looking at the CWE-829 answer + first: `text_search?text=plugin` and `text_search?text=third-party` + (drawn from AVE-2026-00034's own title, not its CWE citation) both + surface **CRE `307-507`**, whose full name is *"Allow only trusted + sources both build time and runtime; therefore perform integrity + checks on all resources and code"* — and whose own ASVS anchor text is: + *"The application must not load or execute code from untrusted + sources, such as loading includes, modules, **plugins**, code, or + libraries from untrusted sources or **the Internet**."* That is close + to a verbatim restatement of AVE-2026-00034's own mechanism + ("load the plugin from https://external.site/plugin.py"). +- **`307-507` links to CWE-353** ("Missing Support for Integrity Check") + — a *different* CWE than CWE-829/494, the ones AVE-2026-00034 itself + currently cites. The CWE-routed first pass could not have found this + CRE by construction: it only ever looks at CREs already reachable from + a CWE the AVE record happens to name. This is the concrete instance of + the exact risk `CONTRIBUTING.md` names — not a hypothetical, one that + happened during this pilot's own first draft. +- **Resolution**: propose `307-507` as the primary link (single closest + mechanism match, found independently of the record's own citations), + and keep `777-470`/`577-260` as secondary/companion links — both are + still real, defensible, and OpenCRE's own data model routinely + supports one Standard linking to several CREs (`CWE:16` alone links to + 5). Also worth carrying back into AVE's own corpus separately from + this pilot: AVE-2026-00034's own `references` could reasonably add + CWE-353 alongside its existing CWE-829/494 citations, since this + search surfaced a real angle on the mechanism AVE's own record + doesn't currently name. Not done in this draft — flagged for a + follow-up, kept out of scope here to avoid conflating the OpenCRE pilot + with an unrelated AVE record edit. +- **Confidence: high on `307-507` specifically because it was found + independently; still high but secondary on the other two.** +- **Second-pass review note**: `307-507`'s own full link list (13 links; + the earlier fetch during drafting only printed the first 8) confirms + CWE-353 is its *only* linked CWE — no CWE-829/494 present anywhere on + it, so the "CWE-routing structurally could not have found this" claim + above holds on the complete data, not a truncated sample. It also + carries a `Related` (not `PartOf`) link to `613-285 Supply chain + management` — the same node that sits in `577-260`'s own parent chain. + OpenCRE's own graph already treats these two CREs as connected to each + other, independent confirmation that proposing both together for one + AVE record is coherent with the existing graph, not an arbitrary + combination assembled for this pilot. + +### 5. [HELD FOR FOLLOW-UP, not in this submission] AVE-2026-00033 (Unsafe Deserialization or Eval Instruction) → CWE-502 → CRE `736-554` + +- **AVE mechanism**: "Deserializing untrusted data using unsafe methods + like Python's `pickle.loads`, unguarded `yaml.load`, **or `eval`/`exec` + on arbitrary strings**...

This crosswalk matches against those 11 rules' real logic, not their names alone, since the two do not always agree (see the hardcoded_c2 gap below).\n\nThe open question from the outreach, whether constraint-guided representation synthesis generalizes onto AVE's behavioral classes or stays genuinely distinct from pattern-based classification, has a real, mixed answer: partial generalization, clean where a Semia rule terminates in a specific effect AVE also names explicitly, genuinely distinct where AVE's granularity is organized by attack narrative and Semia's is organized by dataflow destination. 16 mappings verified across 9 of Semia's 11 rules, field-checked against provenance_vector and behavioral_fingerprint, not category labels.\n\nThree concrete, citable examples of the real daylight: (1) label_unsanitized_context_ingestion (any untrusted value reaching one of five high-priv effects, ungated) keyword-sweeps against roughly two dozen of AVE's prompt-injection-flavored records, but only genuinely verifies against ones that name a specific privileged sink (AVE-2026-00006's crypto_sign, AVE-2026-00042's code_eval); most of AVE's prompt-injection catalog describes the injection vector itself (jailbreak, hidden instruction, context window manipulation, multi-turn persistence) without asserting a terminating privileged effect, so a keyword match is not a structural one. AVE splits by injection surface; Semia collapses by dataflow destination. (2) A rule's own name can promise a match its logic does not deliver: label_hardcoded_c2_communication reads like an obvious fit for AVE-2026-00073 (Static Endpoint Redirect), but the actual Datalog condition requires call_code=\"unresolved_target\", a destination static analysis cannot resolve at all, while AVE-2026-00073's mechanism is the opposite: a fully resolved, literal, committed bad destination. No AVE record currently satisfies this rule's real condition; left unmapped rather than forced. (3) A shape can sit a full abstraction level above what Semia's fact model can represent: AVE-2026-00070 (Distributed Cross-Agent Backdoor Fragments) shares label_dormant_malicious_payload's dormant-until-reassembled narrative, but the mechanism spans multiple agents' memories with an offline, external reassembly step, and Semia's CORE_SCHEMA models exactly one skill() per analysis pass with no multi-agent or cross-session concept in the schema at all. Not a missing rule, a missing dimension; left unmapped.\n\nTwo more things worth surfacing. First, AVE-2026-00003 (Credential exfiltration via agent instruction) is matched by two of Semia's own rules independently, label_implicit_egress_channels (an explicit dataflow edge from a secret value to an untrusted egress call) and label_shadow_credentials (co-presence of a secret-region read and an untrusted-egress-capable skill, checked without requiring an explicit edge), two differently-reasoned Datalog conditions inside one tool converging on the same AVE id. Combined with this record's existing cfgaudit, nova-proximity, and Ramparts matches (see those crosswalks), it is now the record with the broadest independent confirmation across AVE's whole crosswalk set, four separate tools, none sharing code, plus one tool's own two internal rules.

Substantially larger surface than skillsentry, closer in caliber to Ramparts/nova-proximity/Semia.\n\nThree findings worth stating directly rather than leaving implicit. First, the injection category (INJ001-006: eval()/exec() with a non-literal argument, os.system, subprocess shell=True) reads like an obvious match for AVE-2026-00052, but these are pure regex signature matches over dangerous syntax, not a traced dataflow from a caller-supplied parameter to the sink; AVE-2026-00052's own fingerprint specifically requires that taint path. This is the exact same signature-vs-reachability distinction the Ramparts crosswalk already documented for its own CommandInjection rule against this same AVE record, so it is treated the same way here: left as a gap, not forced. Second, IOCDetector matches against a curated malicious IP/domain/URL database, a reputation-list lookup, which is a structurally different approach from AVE's own stated design principle (behavioral fingerprints over signatures, CLAUDE.md hard rule 3); it has no AVE counterpart by design, not by gap. Third, LLMAnalyzer produces free-form findings from an LLM's own judgment with no fixed taxonomy of its own, so there is nothing stable to crosswalk against; left out entirely rather than mapped to a placeholder.\n\nThe persistence category (PER001-007) is close to exhaustive against AVE-2026-00008, which is itself the strongest single match found across either tool in this pass: six of seven rules verify directly against the record's own named examples (cron, systemd, shell-profile modification), and the seventh (a Windows registry Run key) verifies against the fingerprint's general 'executes on login or reboot' language even though the record's own examples are Unix-flavored. The privilege_escalation category (PRI001-005: sudo, chmod 777/+s, setuid/setgid) is a clean, complete miss: AVE's whole Privilege Escalation attack_class operates at the agent/permission-model level (scope creep, delegation, trust transfer), one abstraction level above OS-level Unix privilege primitives, which have no AVE analog at all today.

The manifest is a reviewed, +trusted declaration; nothing enforces that declaration once the +component runs. +#### Security boundary +Reviewed artifact (declared manifest scope) → executed behavior +(actual runtime access). +#### Attacker-controlled input +Skill instruction body directing access to undeclared resources. +#### Missing control +No scope enforcement at the agent-framework layer comparing runtime +tool/resource calls against the component's own declared manifest. +#### Agentic-specific distinction +A manifest's declared scope is meaningful only if something enforces +it against a natural-language-driven agent that can be instructed, in +plain English, to ignore that declaration -- a deterministic program +either has the access compiled in or it doesn't. The instructable gap +between declared and actual scope is the agentic-specific piece. +#### Decision +CLARIFY +#### Rationale +The mitigation metadata already correctly names the fix +(`least_privilege`, `isolate_scope`, `enforcement_point: +agent_framework`), but the prose description reads more as "what +happens" than as a named missing control. Tightening the description +to state the enforcement gap explicitly would resolve this without +changing the mechanism. +#### Confidence +HIGH + +--- + +### AVE-2026-00032 -- Network Reconnaissance Instruction +#### Classification +C +#### Capability +Agent has network connectivity or shell access sufficient to reach +internal hosts and services. +#### Security-relevant behavior +A malicious component instructs the agent to run scans, enumerate +services, or map infrastructure, using network access the skill was +not declared to need. +#### Vulnerability condition +No network-layer segmentation or scope check restricts an agent's +granted network capability to the destinations its declared task +actually requires. +#### Security boundary +Declared task scope → actual network reachability. Distinct from +`AVE-2026-00022`'s boundary in enforcement point (`network_layer` +here, `agent_framework` there), which is the real reason this stays a +separate record rather than merging into it. +#### Attacker-controlled input +Skill instruction body: network/port-scan directive. +#### Missing control +No network segmentation or egress scoping tied to a skill's declared +purpose; the agent's network capability is all-or-nothing rather than +scoped per task. +#### Agentic-specific distinction +Real, but currently implicit. The record as written emphasizes what +the attacker's instruction makes the agent do (classic reconnaissance) +more than the missing network-layer scoping control that makes it +possible from a trusted internal host with no additional exploit +required. +#### Decision +REFRAME +#### Rationale +This is a genuine attack-technique-shaped description (`attack_class: +Reconnaissance - Internal Network Scanning` reads as behavior, not +boundary) sitting on top of a real, distinct vulnerability mechanism +(no per-task network scoping). Reframe the description to lead with +the missing scoping control; keep as a separate record from +`AVE-2026-00022` since the enforcement point genuinely differs +(network layer vs. agent framework). +#### Confidence +MEDIUM + +--- + +### AVE-2026-00035 -- Environment or Sensor Data Manipulation +#### Classification +E +#### Capability +Agent can report tool-sourced sensor, environment, or system-state +observations to an operator or downstream agent. +#### Security-relevant behavior +Component instructs the agent to fabricate, alter, or suppress those +readings before they're reported. +#### Vulnerability condition +No provenance or integrity check verifies that a reported observation +genuinely reflects the underlying tool's real output before it reaches +a decision-maker. +#### Security boundary +Tool response (source of truth) → reported observation (what the +operator or downstream agent actually receives). +#### Attacker-controlled input +Sensor/environment tool-response payload. +#### Missing control +No provenance labeling or integrity verification on tool-response data +carrying sensor/environment readings. +#### Agentic-specific distinction +This is real but needs to be stated, not assumed. Telemetry-integrity +attacks against SCADA/IoT systems are a well-established, pre-LLM +security problem (CWE/ICS territory) -- the Q6 test cuts against this +record if left as-is: a deterministic reporting pipeline with the same +integrity gap would have essentially the same vulnerability. What's +actually agentic-specific is narrower and not yet named in the +record's own text: a natural-language-driven relay can be *instructed* +in plain English to misreport, without requiring the hardware or +firmware compromise a conventional telemetry-spoofing attack needs. +#### Decision +JUSTIFY +#### Rationale +Retain, but the agentic-specific distinction (instructable fabrication +vs. hardware/firmware-level compromise) needs to move from this audit +into the record's own description. As written, nothing in the record +text distinguishes it from a generic ICS/SCADA telemetry-integrity +class that CWE and conventional taxonomy already cover. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00038 -- Excessive Agency - Unbounded Tool Use or Sub-Agent Spawning +#### Classification +D +#### Capability +Agent can use any declared tool and spawn sub-agents. +#### Security-relevant behavior +Component instructs the agent to use any tool at its disposal, spawn +unlimited sub-agents, or "do whatever it takes," removing scope +boundaries and human oversight. +#### Vulnerability condition +As written, this is close to a bare capability statement: "the agent +can act without scope boundaries or oversight checkpoints" describes +an absence of a control, but the record doesn't clearly separate +*that the agent has broad tool access* (a capability, not itself a +flaw) from *no mechanism bounds how that access is used once granted* +(the actual vulnerability). +#### Security boundary +Declared, bounded tool/delegation scope → actual, unbounded runtime +use. The same shape of boundary as `AVE-2026-00022`, applied to tool +use and sub-agent spawning specifically rather than resource access +generally. +#### Attacker-controlled input +Skill instruction body granting unlimited tool use or sub-agent +spawning. +#### Missing control +No ceiling on tool invocations or sub-agent spawning, and no human +checkpoint gating either, once a component's instructions grant +"unlimited" authority. +#### Agentic-specific distinction +Real: sub-agent spawning and recursive capability expansion are +agentic-specific mechanisms with no direct deterministic-program +analog (Q6: a conventional program doesn't spawn new instances of +itself with inherited authority in response to natural-language +instruction). But this needs to be named directly rather than left as +"the agent had a lot of authority and used it," which reads as +capability, not boundary failure. +#### Decision +REWRITE +#### Rationale +A genuine, distinct mechanism exists underneath this (no bound on +tool-use/sub-agent-spawn rate or scope once granted, no human +checkpoint), but the current description doesn't cleanly separate +capability from vulnerability the way `Q7`'s three-line format +requires. This is also the record flagged ambiguous in the prior +owasp_asi audit (ASI02 vs. ASI09 vs. ASI10, none a clean fit) -- +consistent with a record whose underlying vulnerability condition +hasn't been made explicit enough to classify confidently against an +external framework either. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00068 -- CLI Command Composition Risk +#### Classification +A +#### Capability +Agent can issue sequences of CLI commands, none individually +dangerous. +#### Security-relevant behavior +Commands compose through shared OS/shell state (environment variables, +file descriptors, working directory, temp files) into a capability the +task did not authorize, with no single command flagged by +single-command analysis tools. +#### Vulnerability condition +No producer-consumer tracking across a command sequence within one +session -- every existing control (ShellCheck, GTFOBins, LOLBAS, +single-command scanners) evaluates each command in isolation, so the +composition itself is structurally invisible to them. +#### Security boundary +Single-command security review → multi-command behavioral effect. The +boundary is the unit of analysis itself: per-command vs. per-sequence. +#### Attacker-controlled input +None required in the traditional sense -- the record's own text is +explicit that this can occur "entirely within ordinary, benign-looking +developer task scenarios," which is unusual among AVE records and +worth flagging on its own (see Q7 below). +#### Missing control +No cross-command state-flow analysis; every existing tool's unit of +analysis stops at the single command. +#### Agentic-specific distinction +Strong. This is not simply "shells allow multi-step work" (true of any +shell session, deterministic or not) -- the agentic-specific angle is +that an LLM-driven agent can be *guided toward* an unauthorized +composition through many small, individually-benign steps in a way a +human operator following a fixed script would not organically +converge on, and the paper cited (96.59% ASR, 2,525 trials) is +evaluating exactly that model-driven composition behavior, not generic +shell risk. +#### Decision +RETAIN +#### Rationale +This is the cleanest A-classification in Priority 1: a specific, +named missing control (no cross-command analysis unit), a citable +primary source with a concrete attack-success rate, and a boundary +(single-command vs. sequence-level review) that existing tooling +genuinely does not cover. Worth one explicit follow-up, not a +reclassification: since no single attacker-controlled input drives +this the way most AVE records require, the record's `provenance_vector` +and detection guidance should say plainly that this can fire on +entirely benign-looking, non-adversarial task sequences -- worth a +one-line addition, not a structural change. +#### Confidence +HIGH + +--- + +## Sprint 2 — Priority 2: technique-vs-vulnerability records + +### AVE-2026-00009 -- AI Identity Jailbreak via Role-Play or Persona Override +#### Classification +C +#### Capability +Agent operates under safety/alignment constraints configured +independently of the content it processes. +#### Security-relevant behavior +Component instructs the agent to adopt a persona or "developer mode" +without those constraints. +#### Vulnerability condition +No boundary prevents processed content from redefining the agent's own +safety/alignment configuration -- constraints that should be +structurally immutable to in-context instruction are treated as +negotiable. +#### Security boundary +Agent's own configuration (trusted, set once) → content the agent +processes (untrusted, arbitrary). +#### Attacker-controlled input +Skill instruction body: persona-override / unrestricted-mode +directive. +#### Missing control +No enforced separation between "instructions that configure the +agent" and "content the agent merely reads." +#### Agentic-specific distinction +Real. A deterministic program's configuration isn't "talked into" +changing by its own input stream; an LLM's constraints and its input +share the same channel, which is exactly the property this class +exploits. +#### Decision +REFRAME +#### Rationale +Currently reads as attack-technique description ("component instructs +agent to pretend...") rather than naming the configuration/content +separation failure underneath it.

naming +"operator-visibility boundary" explicitly in the description would +remove any ambiguity with a plain confidentiality framing. +#### Confidence +HIGH + +--- + +### AVE-2026-00014 -- False Authority Claim via Trust Escalation Impersonation +#### Classification +B +#### Capability +Agent can act on authority claims present in content it processes. +#### Security-relevant behavior +Component falsely claims to originate from Anthropic, OpenAI, Google, +Microsoft, or the operator. +#### Vulnerability condition +No mechanism authenticates in-content authority claims -- any content +can assert arbitrary authority with no verification step. +#### Security boundary +Claimed identity (asserted in content) → actual, verifiable identity +(not checked against anything). +#### Attacker-controlled input +Skill instruction body: false-authority framing. +#### Missing control +No authentication of in-band identity/authority claims. +#### Agentic-specific distinction +Present but not unique to agentic systems specifically (authority +spoofing in content is a general social-engineering pattern); what +makes it agentic-relevant is that the agent, not a human, is the one +deferring to the claim. +#### Decision +CLARIFY +#### Rationale +Mitigation metadata already names the fix (`verify_identity`); the +description should state "no authentication of in-content authority +claims" as the violated property rather than only describing the +impersonation technique. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00023 -- Model Context Window Manipulation +#### Classification +B +#### Capability +Agent's effective attention to system-prompt and safety content can +vary with context volume. +#### Security-relevant behavior +Component floods the context window with content to push safety +constraints out of the active window. +#### Vulnerability condition +Safety and system constraints have no persistence guarantee +independent of their position in the context window -- they can be +positionally evicted rather than remaining structurally binding. +#### Security boundary +Constraint binding (should be persistent) → context-window position +(where it actually, and non-persistently, lives). +#### Attacker-controlled input +Tool/skill output volume flooding the context window. +#### Missing control +No mechanism keeps safety constraints binding independent of how much +content has since entered the context. +#### Agentic-specific distinction +Strong and inherent to the architecture: a conventional program's +rules aren't degraded by input volume the way an LLM's effective +adherence to early-context content can be (Q6 cuts clearly in favor of +agentic-specificity here). +#### Decision +CLARIFY +#### Rationale +Mechanism is real and architecture-specific; description already +gestures at it ("those constraints no longer in scope") but doesn't +name it as explicitly as Q3 requires. +#### Confidence +HIGH + +--- + +### AVE-2026-00025 -- Conversation History Injection +#### Classification +B +#### Capability +Agent relies on conversation history to infer prior user intent and +consent. +#### Security-relevant behavior +Component injects fabricated prior-turn content into context. +#### Vulnerability condition +No integrity or provenance check distinguishes genuine prior-turn +history from content merely styled to resemble it within the current +turn's context. +#### Security boundary +Genuine session history (should be structurally distinct) → arbitrary +content shaped to resemble history (currently indistinguishable to the +model). +#### Attacker-controlled input +Fabricated prior-turn content injected into context. +#### Missing control +No structural or cryptographic separation between real history and +content merely formatted to look like it. +#### Agentic-specific distinction +Real: this specifically exploits that conversation history is +represented in the same token stream as everything else, with no +architectural marker of authenticity. +#### Decision +CLARIFY +#### Rationale +Genuine, distinct mechanism; needs the "no structural separation of +real vs. simulated history" property stated directly rather than left +implicit in "embeds fake prior conversation history." +#### Confidence +MEDIUM + +--- + +### AVE-2026-00027 -- Multi-Turn Attack - Instruction Persistence Across Conversations +#### Classification +B +#### Capability +Agent's stated behavior can be shaped by instructions that ask it to +"remember" something. +#### Security-relevant behavior +Component instructs the agent to retain and re-apply malicious +instructions across turns, memory resets, or new sessions. +#### Vulnerability condition +No boundary prevents a single untrusted, single-session instruction +from converting itself into cross-session persistent behavior via the +agent's own compliance with a "remember this" directive. +#### Security boundary +Single-session, untrusted instruction → cross-session persistent +behavior. +#### Attacker-controlled input +Instruction directing retention across turns/sessions. +#### Missing control +No check on instructions that specifically target the agent's own +persistence/memory behavior as their payload. +#### Agentic-specific distinction +Real, but overlaps substantially with `AVE-2026-00019` (Agent Memory +Poisoning) and `AVE-2026-00070` (Distributed Cross-Agent Backdoor +Fragments). Flagged for the Sprint 4 cross-record consistency pass: +worth confirming whether this record's mechanism (instruction-driven +self-persistence via agent compliance) is genuinely distinct from +00019's (direct write to a persistent memory store) rather than two +labels for the same underlying condition. +#### Decision +CLARIFY +#### Rationale +Real mechanism, but its boundary with 00019 needs to be made explicit +in both records' text, not just implied by different titles. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00029 -- Homoglyph or Unicode Obfuscation Attack +#### Classification +A +#### Capability +Human reviewers evaluate text visually; the model processes Unicode +codepoints. +#### Security-relevant behavior +Component uses homoglyphs, zero-width characters, or bidirectional +control codes so instructions appear innocuous to a human reviewer +while remaining fully executable by the model. +#### Vulnerability condition +No canonicalization or normalization step reconciles what a human +reviewer visually sees with what the model actually processes at the +codepoint level. +#### Security boundary +Human visual review → model-level codepoint processing. +#### Attacker-controlled input +Text content containing homoglyph, zero-width, or bidi control +characters. +#### Missing control +No Unicode normalization/canonicalization check before human review. +#### Agentic-specific distinction +Strong: this specifically exploits the gap between how a human +reviewer and an LLM each consume the same bytes, which has no +meaningful analog in reviewing a deterministic program's source. +#### Decision +RETAIN +#### Rationale +Already the cleanest-written record in this priority group -- the +description states the human-vs-model processing divergence directly. +No change needed. +#### Confidence +HIGH + +--- + +### AVE-2026-00030 -- Privilege Escalation via False Role Claim +#### Classification +A +#### Capability +Skills can implement role-based access checks against user-supplied +claims. +#### Security-relevant behavior +Component instructs the agent to grant elevated privileges whenever a +user or external party claims a privileged role. +#### Vulnerability condition +Role-based access control is implemented by trusting a bare, +self-asserted claim with no backing credential or authentication step. +#### Security boundary +Claimed role → actually-verified role (never checked). +#### Attacker-controlled input +Skill instruction body: role-claim trust rule. +#### Missing control +No authentication step backing role claims. +#### Agentic-specific distinction +Present, though the underlying pattern (trusting an unauthenticated +claim) is a conventional access-control failure; the agentic angle is +that a natural-language instruction can install this pattern as the +component's entire authorization logic with no code review surface. +#### Decision +RETAIN +#### Rationale +Already clean and explicit ("bypassing all actual authentication"). +No change needed. +#### Confidence +HIGH + +--- + +### AVE-2026-00037 -- Prompt Injection via Image or Vision Input +#### Classification +B +#### Capability +Multimodal agents can read text embedded in images. +#### Security-relevant behavior +Component instructs the agent to execute instructions visible in +images, bypassing text-level security scanning entirely. +#### Vulnerability condition +Untrusted-content handling boundaries exist for text but have no +equivalent for text rendered inside images -- the same class of +content is trusted or untrusted depending on which modality carries +it. +#### Security boundary +Text-channel untrusted-content boundary (exists) → image-channel +untrusted-content boundary (does not exist). +#### Attacker-controlled input +Image/screenshot pixel content. +#### Missing control +No cross-modal equivalent of existing text-content trust boundaries. +#### Agentic-specific distinction +Strong: multimodal instruction-following with no modality-consistent +trust model is architecture-specific to LLM-driven agents. +#### Decision +CLARIFY +#### Rationale +Mechanism is real and already partly stated ("completely bypasses +text-level security scanning");

+`AVE-2026-00024`, content-type misrepresentation) by scope -- this one +is specifically about representational deception targeting automated +scanners. +#### Decision +RETAIN +#### Rationale +Already well-scoped and explicitly differentiated from its nearest +neighbors in the record's own text. No change needed. +#### Confidence +HIGH + +--- + +## Sprint 3 — Priority 3: conventional vs. agentic-specific records + +This group is where Decision Rule §7's test does the most work: several +of these are conventional vulnerability classes (CWE territory) that +happen to occur inside agent components. The question per record is +whether AVE names a real, distinct reason it belongs here beyond that +coincidence. + +### AVE-2026-00004 -- Arbitrary Code Execution via Shell Pipe Injection +#### Classification +E +#### Capability +Agent with shell/code-execution tool access follows embedded commands. +#### Security-relevant behavior +Component embeds shell pipe patterns (`curl | bash`) in natural-language +instructions. +#### Vulnerability condition +Conventional command-injection (CWE-78 territory) delivered through +natural language rather than code. +#### Security boundary +Trusted instruction content → shell execution, with no boundary +between the two once a component's text is treated as instruction. +#### Attacker-controlled input +Skill instruction body: curl|bash / wget|sh directive. +#### Missing control +No distinction between natural-language content that merely describes +a step and natural-language content that constitutes an executable +directive. +#### Agentic-specific distinction +Already stated in the record's own text and holds up: existing SAST +scanners are built to find command injection in *code*, not in +natural-language instructions that produce the same effect once an +agent follows them. The mechanism is conventional; the delivery +channel evading conventional tooling is the real agentic-specific +piece. +#### Decision +JUSTIFY +#### Rationale +Q6 cuts against pure novelty (a deterministic program blindly piping +untrusted config into a shell has the same flaw), but the record +already names its real distinction (NL delivery invisible to SAST) -- +retain as currently justified, not merged into generic CWE-78. +#### Confidence +HIGH + +--- + +### AVE-2026-00005 -- Recursive File System Destruction via Destructive Command Injection +#### Classification +E +#### Capability +Agent with filesystem/shell access follows embedded destructive +commands. +#### Security-relevant behavior +Component embeds `rm -rf /`-class commands inside legitimate-looking +setup/cleanup instructions. +#### Vulnerability condition +Same shape as `AVE-2026-00004`: conventional destructive-command +pattern, delivered via natural language. +#### Security boundary +Same as 00004: instruction content → shell execution, no boundary +between them. +#### Attacker-controlled input +Skill instruction body: recursive deletion command. +#### Missing control +Same as 00004. +#### Agentic-specific distinction +Same NL-delivery-evades-SAST argument as 00004, already stated. +#### Decision +JUSTIFY +#### Rationale +Structurally near-identical to `AVE-2026-00004` -- flagged for the +Sprint 4 cross-record pass to confirm the two are worth keeping +separate. Leaning yes: impact differs materially (arbitrary code +execution vs. irrecoverable data loss with no code-execution +requirement), which is a real severity and detection distinction, not +just a labeling one. +#### Confidence +HIGH + +--- + +### AVE-2026-00033 -- Unsafe Deserialization or Eval Instruction +#### Classification +E +#### Capability +Agent follows instructions to deserialize/evaluate externally-supplied +data. +#### Security-relevant behavior +Component instructs use of `pickle.loads`, unguarded `yaml.load`, or +`eval`/`exec` on untrusted strings. +#### Vulnerability condition +Conventional RCE-via-unsafe-deserialization (CWE-502/CWE-94), +delivered via natural language. +#### Security boundary +Instruction content → unsafe deserialization/eval call, no boundary +between them. +#### Attacker-controlled input +Skill instruction body: eval/pickle/yaml.load of untrusted data. +#### Missing control +Same NL-vs-code detection gap as 00004/00005. +#### Agentic-specific distinction +Same argument, same standard of evidence as 00004/00005. +#### Decision +JUSTIFY +#### Rationale +Third member of the same structural family as 00004/00005.

This is a genuine amplification specific to +LLM-mediated file access, not just "secrets in source code again." +#### Decision +JUSTIFY +#### Rationale +The record earns its place: conventional root cause, but a real, +already-stated agentic amplification (co-location with a +prompt-injection-readable context) that a traditional secrets-scanner +finding wouldn't capture. +#### Confidence +HIGH + +--- + +### AVE-2026-00049 -- HTTP Host Header Injection via Agent-Initiated Request +#### Classification +E +#### Capability +Agent-initiated components can set outbound HTTP request headers. +#### Security-relevant behavior +Component sets a Host (or X-Forwarded-Host/X-Original-URL) header that +doesn't match the declared target, redirecting the request. +#### Vulnerability condition +This is the well-known, conventional Host-header-attack class +(PortSwigger's own documented research area), unchanged in mechanism +regardless of what constructs the request. +#### Security boundary +Declared target endpoint → actual request destination (header- +controlled, not endpoint-controlled). +#### Attacker-controlled input +Outbound HTTP Host / X-Forwarded-Host / Forwarded header. +#### Missing control +No validation that outbound Host header values match the declared +endpoint before the request is sent. +#### Agentic-specific distinction +This is the weakest-justified record in Priority 3. Nothing in the +current text states why an *agent-initiated* Host-header attack is +mechanism-distinct from the same attack made by any other HTTP client. +A plausible real distinction exists but isn't written down: an agent +frequently constructs request parameters (including headers) from +content it has just processed, in a way a static HTTP client +configuration doesn't -- making attacker-controlled header values +reachable through indirect prompt injection rather than requiring +direct network access to the client. That's a real, statable +difference; it just isn't stated yet. +#### Decision +JUSTIFY +#### Rationale +Recommend the record explicitly add the injection-reachability +argument above. Without it, this reads as a straight port of a +well-known web-security class into an agentic component with no +demonstrated distinction, and would be a reasonable MERGE/DEPRECATE +candidate in favor of citing the general class directly. +#### Confidence +LOW + +--- + +### AVE-2026-00052 -- Command Injection via Unsanitized Tool-Call Parameter in MCP Server Implementation +#### Classification +E +#### Capability +An MCP tool's own server-side handler processes caller-supplied +parameter values. +#### Security-relevant behavior +The handler passes a parameter value into a shell/system-command +execution function without sanitization. +#### Vulnerability condition +Conventional command injection (CWE-78), located in the tool's own +implementation code. The record is explicit that no LLM reasoning or +instruction is required to trigger it at all. +#### Security boundary +Caller-supplied parameter → shell execution, entirely inside the +tool's own server code, with no agent-behavior boundary involved. +#### Attacker-controlled input +MCP tool-call parameter value. +#### Missing control +No input sanitization/allowlisting in the server's own handler -- +a pure implementation bug. +#### Agentic-specific distinction +Weak at the mechanism level (this is not an agentic vulnerability in +any behavioral sense; the record's own text says the attack is +"independent of any agent instruction or prompt content"). The +argument offered is a detection-ecosystem one: prompt-injection +scanners, which dominate this space, structurally cannot find it +because there's no instruction text to match. +#### Decision +JUSTIFY +#### Rationale +This is the hardest call in the audit so far. AVE cataloging a +conventional server-implementation bug is defensible only as a +coverage argument (MCP servers are part of the agentic supply chain +AVE's consumers scan, and no other part of their pipeline will catch +this), not a behavioral/mechanism argument. Worth an explicit maintainer +decision on whether that coverage argument is sufficient grounds for a +distinct AVE record, versus this belonging in a general AppSec/SCA +tool's remit with AVE cross-referencing it rather than cataloging it +directly. Same question applies to `AVE-2026-00053` (Sprint 4). +#### Confidence +LOW + +--- + +### AVE-2026-00054 -- Code-Execution Sandbox Escape via JavaScript Prototype-Chain Traversal +#### Classification +E +#### Capability +A code-execution tool runs agent-submitted or agent-generated code +inside an intended sandbox boundary. +#### Security-relevant behavior +A payload uses prototype-chain traversal to reach the host runtime's +global scope, escaping the sandbox. +#### Vulnerability condition +Conventional sandbox-escape (a pre-LLM, well-studied class in browser +and VM security), located in the sandbox's own containment failure. +#### Security boundary +Sandboxed execution context → host runtime, a boundary the sandbox +itself fails to hold. +#### Attacker-controlled input +Code submitted to a code-execution/sandbox tool. +#### Missing control +The sandbox's own isolation doesn't hold against prototype-chain +traversal -- a containment bug, not an instruction-following one. +#### Agentic-specific distinction +Not strongly stated. The record correctly differentiates itself from +`AVE-2026-00042` (how malicious code gets in) by scope (what happens +once code is already running), but doesn't argue why an +*agent*-execution sandbox is more exposed to this than any other +sandboxed code-execution environment. +#### Decision +JUSTIFY +#### Rationale +A real, statable agentic angle likely exists (LLM-generated code may +incidentally produce prototype-chain-triggering patterns without +adversarial intent far more often than human-authored code would, +widening the practical trigger surface even absent an attacker) but +isn't in the record yet. Recommend adding it explicitly rather than +leaving the distinction implicit. +#### Confidence +LOW + +--- + +### AVE-2026-00061 -- TLS Certificate Verification Disabled in Agent Component Configuration +#### Classification +E +#### Capability +A component's outbound connections can be configured with or without +TLS verification. +#### Security-relevant behavior +Configuration disables certificate verification for the component's +own outbound calls. +#### Vulnerability condition +Conventional insecure-configuration (CWE-295), unchanged by what +consumes the connection. +#### Security boundary +Configured verification state → actual MITM exposure. +#### Attacker-controlled input +A declared configuration flag (`verify=False`, +`rejectUnauthorized: false`). +#### Missing control +No enforcement preventing verification from being disabled at all, or +no detection of the disabled state. +#### Agentic-specific distinction +None stated in the record, and none obvious. This is the weakest +agentic-distinction candidate found in the audit so far. +#### Decision +DEPRECATE-OR-JUSTIFY +#### Rationale +A plausible distinction exists (a MITM'd response over a +verification-disabled connection often becomes direct agent context +the model acts on, unlike a traditional app where a tampered response +might just render on a screen a human evaluates with some skepticism) +but nothing in the record states it. Recommend either adding that +argument explicitly or treating this as a CWE-295 crosswalk entry +rather than a standalone AVE record -- as written, it doesn't clear +Decision Rule §7's bar. +#### Confidence +LOW + +--- + +### AVE-2026-00062 -- Unpinned Dependency Version Allowing Supply Chain Substitution +#### Classification +E +#### Capability +A component can declare dependencies by mutable specifier rather than +exact version or hash. +#### Security-relevant behavior +An unpinned dependency reference lets the resolved artifact silently +diverge from what was reviewed. +#### Vulnerability condition +Conventional software-supply-chain risk (dependency-confusion / +unpinned-dependency territory), well-established in general package- +ecosystem security independent of agents. +#### Security boundary +Reviewed artifact (at pin time) → executed artifact (at resolution +time) -- but this boundary exists for any unpinned dependency in any +software, not agent components specifically. +#### Attacker-controlled input +A declared dependency reference lacking version pinning or a content +hash. +#### Missing control +No pinning/hash verification at declaration time. +#### Agentic-specific distinction +Not stated, and weaker than its neighbors `AVE-2026-00074` (dead-anchor +reclamation, whose distinction is explicit: the anchor was pinned and +correct *when written*, and pinning wouldn't have helped) and +`AVE-2026-00066` (hallucinated-name squatting, whose distinction is +explicit: the attack surface is the *model's own hallucination*, not a +human's config choice). This record reads as the generic "pin your +dependencies" case those two more specific records already imply. +#### Decision +JUSTIFY-OR-MERGE +#### Rationale +Candidate for merging into a broader agentic-supply-chain umbrella +alongside 00074/00075/00034/00066, or for an explicit agentic-specific +argument (e.g., agent-authored or agent-approved dependency changes +move at higher velocity and lower human-review depth than +conventional software supply chains, making unpinned drift more likely +to go unnoticed).

Decision: RETAIN. +``` +Capability: An MCP client spawns a server as a subprocess using command/args from configuration data. +Vulnerability: No validation gate exists between untrusted configuration data and the process-spawn boundary. +Impact: Arbitrary OS command execution under the client's privileges before any protocol handshake occurs. +``` + +### AVE-2026-00056 -- Zero-Click Exfiltration via Markdown Image Auto-Fetch +**A** | agent-generated response content → client's automatic +rendering (an unmonitored channel) | No inspection of response content +for embedded exfiltration channels before client rendering acts on it. +Decision: RETAIN. +``` +Capability: Clients automatically render markdown/rich-content references in agent responses. +Vulnerability: No inspection of agent-generated response content for embedded exfiltration channels before automatic rendering fetches them. +Impact: Zero-interaction data exfiltration requiring no tool call and no obfuscation. +``` + +### AVE-2026-00058 -- Deceptive Skill Trigger or Activation-Scope Manipulation +**B** | declared manifest trigger/description → actual implemented +behavior | No verification that declared triggers match real behavior +before invocation decisions are made. Decision: CLARIFY. +``` +Capability: A skill's declared manifest trigger/description determines when it gets invoked. +Vulnerability: No verification checks that a declared trigger matches the skill's actual implemented behavior before invocation. +Impact: Over-broad or implicit invocation in contexts the skill's real behavior does not warrant. +``` + +### AVE-2026-00059 -- Fragmented Cross-Description Prompt Injection (ShareLock-Class) +**A** | per-description review (isolated) → multi-description +composition (never reviewed as a whole) | No cross-description, +holistic review step exists. Real, verified primary source +(ShareLock, arXiv:2606.27027). Decision: RETAIN. +``` +Capability: MCP tool descriptions across multiple tools/servers are individually reviewed for malicious content. +Vulnerability: No cross-description review step exists; review is structurally confined to one description at a time. +Impact: A complete malicious instruction assembles at inference time with no single reviewable artifact ever having existed. +``` + +### AVE-2026-00060 -- STDIO Transport Shell Injection +**E** | tool-call parameters → host shell, in shared SDK code | No +sanitization gate in the shared transport-layer implementation, wholly +independent of agent instruction. Stronger agentic-ecosystem argument +than `00052`/`00053`: this lives in shared MCP SDK code, not one +server's bespoke handler, so the blast radius spans every server built +on an affected SDK. Decision: JUSTIFY, Confidence MEDIUM. +``` +Capability: MCP SDK STDIO transport implementations pass tool-call parameters to a host shell. +Vulnerability: No sanitization gate exists in the shared transport-layer implementation, independent of any agent instruction. +Impact: Remote code execution across every server built on an affected SDK -- a supply-chain-scale blast radius, not one server's bug. +``` + +### AVE-2026-00063 -- Human Approval Gate Bypassed via Declarative Configuration +**A** | instruction-level review (exists) → configuration-level review +(does not exist) | No requirement that safety-relevant config flags +receive the same review rigor as instruction text. Explicitly +differentiated from `00048` in its own text. Decision: RETAIN. +``` +Capability: Components can declare configuration flags controlling whether human approval is required. +Vulnerability: No requirement that safety-relevant configuration flags receive the same review scrutiny as instruction text. +Impact: A required human-in-the-loop control is silently removed with no instruction-level signal a reviewer would catch. +``` + +### AVE-2026-00064 -- Zero-Click Code Execution via Project-Load Auto-Run Configuration +**A** | passive action (opening a project) → code execution, no +confirmation | No confirmation gate on auto-run behavior triggered +passively rather than by explicit tool call. Decision: RETAIN. +``` +Capability: IDE/dev-environment configuration can declare commands to run automatically on project load. +Vulnerability: No confirmation gate exists for auto-run behavior triggered by a passive action rather than an explicit tool call. +Impact: Code execution requiring no action beyond opening a compromised project directory. +``` + +### AVE-2026-00065 -- A2A Agent Card Poisoning +**A** | descriptive capability/identity metadata → instruction, once +loaded into reasoning context | Same metadata-vs-instruction gap as +`00002`/`00041`, in the A2A protocol's genuinely distinct surface (no +`.well-known` path, no `tool.description` field). Decision: RETAIN. +``` +Capability: A host agent reads a remote agent's A2A card to plan task delegation. +Vulnerability: No boundary separates the card's descriptive metadata from executable instruction once loaded into the host's reasoning context. +Impact: Delegation planning hijacked by a malicious remote agent's self-declared, unverified metadata. +``` + +### AVE-2026-00066 -- Hallucinated Skill-Name Squatting (HalluSquatting) +**A** | model's own hallucinated belief → fetch/install action | No +registry-existence or publisher-identity check before acting on a +model-generated resource name. Distinct entry point: no +attacker-controlled content anywhere in the interaction.

Real, citable research (96% success rate). Decision: RETAIN. +``` +Capability: A downstream skill can consume another skill's output as part of its own decision logic. +Vulnerability: No requirement exists for a downstream skill to independently re-verify a trust or authorization claim in an upstream skill's output. +Impact: Harmful actions approved based on a spoofable trust credential no single skill's isolated review would ever catch. +``` + +### AVE-2026-00069 -- Multimodal Image-Hidden Instructions (SkillCamo) +**A** | text-only review pipeline → bundled image resource (never +decoded for review) | No visual/multimodal decoding step exists in +static review. Decision: RETAIN. +``` +Capability: Multimodal agents can decode and act on bundled image content within a skill package. +Vulnerability: No visual/multimodal decoding step exists in the text-only static-review pipeline covering the rest of the package. +Impact: Instructions invisible to every current text-based scanner execute once a multimodal agent processes the resource. +``` + +### AVE-2026-00070 -- Distributed Cross-Agent Backdoor Fragments +**A** | dormant, per-agent fragments → externally reassembled, +post-hoc payload | No anomaly detection for encoded fragments +inconsistent with a tool's stated function, and no cross-agent +correlation of dormant fragments. Decision: RETAIN. +``` +Capability: Tools deliver observations to agents that persist in memory/context after the call. +Vulnerability: No anomaly detection or cross-agent correlation catches a fragmented payload no single session could ever contain enough of to detect. +Impact: A complete backdoor exists and becomes executable only after the fact, entirely outside any single session's visibility. +``` + +### AVE-2026-00071 -- MCP Daemon Redirect via DOCKER_HOST +**A** | expected local daemon → actual, redirected remote daemon +(unverified) | No verification that a declared daemon target matches +the expected local daemon before build/run/pull proceeds. Decision: +RETAIN. +``` +Capability: Components can declare a container daemon connection target via configuration. +Vulnerability: No verification confirms a declared daemon target is the expected local daemon before operations proceed against it. +Impact: Secrets and bind-mounted data are exposed to whatever infrastructure actually receives the redirected connection. +``` + +### AVE-2026-00076 -- Natural-Language Steering of an Approval Classifier Subagent +**A** | steering text (targets the checker) → classifier's approve/deny +judgment | No boundary prevents the same class of natural-language +content that steers a primary agent from also steering the classifier +meant to check it. Decision: RETAIN. +``` +Capability: A committed configuration file can declare natural-language steering text consumed by a safety-classifier subagent. +Vulnerability: No boundary prevents natural-language content from probabilistically steering the classifier meant to check an agent's actions, the same way it steers the agent itself. +Impact: Auto-approval of shell/MCP/Fetch calls the classifier would otherwise flag, via a committed repository file. +``` + +### AVE-2026-00077 -- Cross-Origin Tool and Resource Declaration +**A** | single server's trust boundary → multiple, unrelated actual +origins within it | No per-origin trust segmentation within one +server's own declared manifest. Decision: RETAIN. +``` +Capability: A single MCP server's manifest can declare tools/resources whose URLs span multiple distinct domains. +Vulnerability: No per-origin trust segmentation exists within one server's declared surface. +Impact: A minority-domain tool or resource can hijack context intended for the trusted majority origin, with no deception required. +``` + +### AVE-2026-00079 -- Plan Hijacking via False Completion Signal +**A** | declared plan (N steps) → actual executed trace (fewer steps, +unverified) | No plan-to-execution-trace verification gates a +self-reported completion signal. Decision: RETAIN. +``` +Capability: An orchestrator tracks a declared plan and invokes a final step based on agent-reported status. +Vulnerability: No verification compares the actual executed step count against the declared plan before accepting a self-reported completion signal. +Impact: Remaining planned steps, including verification steps, are silently skipped. +``` + +--- + +## Sprint 4 cross-record consistency finding + +A recurring pattern surfaced across this audit: a large share of AVE's +prompt-injection-shaped records (`00002`, `00016`, `00020`, `00028`, +`00041`, `00043`, `00044`, `00065`) all realize the *same* underlying +vulnerability property -- no boundary distinguishes untrusted content +from instruction -- at *different* attacker-controlled-input surfaces +(tool schema, RAG document, agent-to-agent message, user upload, +server-card, rich UI, async result, A2A card). This is architecturally +coherent, not redundant: Q4 (attacker-controlled input) genuinely +differs for each, and several records already explicitly differentiate +themselves from their nearest neighbors in their own text (`00041` vs. +`00002`, `00065` vs. `00041`, `00044` vs. the rest). The recommendation +is not to merge these, but to name the shared underlying property +explicitly somewhere central (see R-001 in the findings below) so a +reader encounters it as one recognized pattern with many instances, +rather than reconstructing it record-by-record the way this audit had +to. + +A second, smaller pattern: `00019`, `00027`, `00031`, `00035`, `00070` +all use "poisoning" in their titles or descriptions but name four +genuinely different mechanisms (direct memory-store write, instructed +cross-session self-persistence, self-referential feedback-signal +corruption, tool-response fabrication, and dormant multi-agent +fragment reassembly, respectively). Confirmed distinct on inspection, +not a conflation problem -- but worth a shared terminology note so +"poisoning" reads as a family of related-but-distinct mechanisms +rather than implying a single pattern. + +A third pattern, the "unauthenticated in-content claim" family +(`00012`, `00014`, `00030`): false permission grant, false authority +claim, and false role claim all share the identical missing control +(no authentication backs an in-content claim) but differ in exactly +what's claimed and what it unlocks. Confirmed legitimately distinct, +same reasoning as the poisoning family above. + +--- + +## Deliverable 1 — Full 80-record matrix + +| AVE ID | Class | Boundary | Decision | +|---|---|---|---| +|

Recommend a short cross-referencing note (in +`docs/specs/`, not a schema change) naming this as a recognized family, +linking all eight, the same treatment already given to the +"unauthenticated in-content claim" family (00012/00014/00030) and the +"poisoning" family (00019/00027/00031/00035/00070) once this audit +confirmed each was genuinely distinct rather than a labeling accident. + +**R-002, resolve the three structural-decision records deliberately, +not by default.** AVE-2026-00009 (REFRAME), 00032 (REFRAME), and 00038 +(REWRITE) are the only records in the corpus whose current text doesn't +yet name a boundary failure explicitly enough to stand alone. Each has +a real, identifiable mechanism (documented above); the fix is rewriting +the `description`/`behavioral_fingerprint` text, not changing the +`ave_id` or removing the record. Treat as three concrete, scoped +follow-up edits, not a larger project. + +**R-003, get an explicit maintainer decision on implementation-bug +records.** AVE-2026-00052, 00053, and 00060 are pure code-level +implementation flaws in MCP tooling with no agent-instruction or +behavioral component at all -- the records themselves say so. AVE's +value-add for these is a coverage argument (this is part of the +agentic supply chain AVE's consumers already scan, and nothing else in +their pipeline will catch it), not a mechanism-level agentic +distinction. This is a legitimate but different kind of claim than the +rest of the corpus makes, and deserves a deliberate, stated decision +(keep with the coverage rationale made explicit, or scope AVE away from +pure implementation bugs going forward) rather than silence. + +**R-004, revisit the weakest agentic-distinction records as a group.** +AVE-2026-00049, 00061, and 00062 are the three records where a real +agentic-specific argument plausibly exists but isn't yet written down, +and where, absent that argument, each reads as a bare port of an +existing CWE class into an agentic component with no demonstrated +distinction.

The mechanisms, which are four rather than one: + +1. **The sandbox switched off outright.** Codex `sandbox_mode = "danger-full-access"`, Cursor `type: "insecure_none"`, Claude Code `sandbox.filesystem.disabled: true`. +2. **The sandbox left on but widened.** Codex `[sandbox_workspace_write]` `network_access = true` and `writable_roots` reaching outside the workspace; Gemini `tools.sandboxAllowedPaths` exposing `/` or `~`, and `tools.sandboxNetworkAccess: true`. +3. **The confinement helpers repointed.** Claude Code `sandbox.bwrapPath` and `sandbox.socatPath` (honored only from managed settings, so anomalous anywhere else), `sandbox.excludedCommands` carrying a wildcard or a shell, `sandbox.network.allowUnixSockets` naming a privileged daemon socket such as `docker.sock`, `sandbox.filesystem.allowWrite` on `$PATH` or a shell rc file. +4. **The same posture reached without touching a sandbox key at all.** Codex's named permission profiles: `default_permissions` selects a `[permissions.]` profile whose `network` block carries `enabled`, `proxy_url`, `socks_url`, `dangerously_allow_all_unix_sockets` and `dangerously_allow_non_loopback_proxy`, and whose `filesystem` block can grant `":root"` or a credential path. `extends` genuinely inherits, so a profile cannot be judged from its own table. An indicator list keyed on `sandbox_mode` misses this fourth mechanism entirely. + +**Is "widened" a different class from "off"?** Earlier read was maybe. After building it: no. Both are the same check, read a declared value and compare it to the default. The difference is blast radius, not kind. Mechanism 4 is the one that is genuinely different, because it reaches the same posture through a key with no "sandbox" in the name. + +**The hardening-not-weakening trap, extended.** Beyond `disableTmpWrite`, `exclude_tmpdir_env_var` and `exclude_slash_tmp`, three more instances turned up while building v1.12.0, all measured: Grok's `[plugins] disabled` (naming a plugin to discover but not activate hardens); qwen's `memory.autoSkillConfirm`, whose default is **true**, so the weakening value there is `false`, the inverse of every `disable*` key; and Codex's profile `filesystem` block, where across 69 real `.codex/config.toml` files the decisions are `deny` 177, `write` 72, `read` 53, `none` 51, so the block's presence is overwhelmingly hardening and only a granting direction on a sensitive target is a finding. One more for an `indicators_of_compromise` list: a read grant on `~/.ssh/id_ed25519.pub` is not credential exposure, and a real profile in that corpus carries exactly that. + +### The two new gaps + +**An automated reviewer switched off by config.** Codex's `[features.guardianv2]` decides whether its own security reviewer runs (`enabled`), at what score it escalates to a blocking review (`review_threshold`, default `0.5`, a number the reviewer's own prompt states), and what prompt it is given (`classifier_instructions`). The prompt half is `AVE-2026-00076` and is mapped above. The other two are not: `AVE-2026-00063` is explicitly a bypassed *human*-approval step, and Guardian v2 is an automated reviewer. `features` is not on Codex's project-layer denylist, so a committed `.codex/config.toml` sets all three; verified against codex `0.150.0-alpha.7` by reading the effective config back through its app server in a trusted directory, with a denylisted key and an ordinary key as controls. -| Config surface | Example files / keys | Example rules | -|---|---|---| -| Telemetry / endpoint redirect | `OTEL_EXPORTER_OTLP_*ENDPOINT` to a non-local collector, `ANTHROPIC_BASE_URL` off Anthropic, model or provider `base_url` over cleartext | CFG005, CFG046, CFG071 | -| Sandbox weakening in config | `sandbox.excludedCommands` wildcard/shell, `bwrapPath`/`socatPath`, `allowUnixSockets` naming `docker.sock`; Gemini `tools.sandboxAllowedPaths` exposing `/`; Codex `danger-full-access` and `[sandbox_workspace_write] network_access`; Cursor `type: insecure_none` | CFG022, CFG061, CFG064, CFG079, CFG095 | -| Container / daemon posture | `DOCKER_HOST` or `-H` at a remote `tcp://`/`ssh://` daemon; `DOCKER_CONTENT_TRUST=0`, `--disable-content-trust`, `--insecure-registry`; Chromium `--utility-cmd-prefix`, `--renderer-cmd-prefix`, `--gpu-launcher`, `--browser-subprocess-path` in MCP `args` | CFG082, CFG084, CFG083 | -| MCP network / transport posture | bind `0.0.0.0`/`[::]`; wildcard CORS origin, escalating when auth is disabled in the same `env`; `type: sse`; `HTTP_PROXY`/`HTTPS_PROXY`/`ALL_PROXY` off loopback; HTTP transport without log redaction | CFG018, CFG066, CFG058, CFG021, CFG069 | -| Cleartext endpoint, distinct from TLS verification disabled | a committed `http://` MCP server URL, model base URL, or A2A `agent_card_url` | CFG049, CFG071, CFG097 | -| Natural-language steering of an approval classifier | Cursor `.cursor/permissions.json` `autoRun.allow_instructions` | CFG094 | +**A repository granting browser or desktop access.** Codex's `[browser_use]` grants per-origin `access`, `downloads`, `uploads` and `full_cdp_access` (full Chrome DevTools Protocol, so script execution plus cookie and storage access inside the browser session), and `[computer_use]` grants control of desktop applications by bundle id, AUMID or executable. The value type is an enum of exactly `allow` and `deny`, so there is no ask state and `allow` is unambiguously the weakening direction. This is deliberately **not** filed under `AVE-2026-00063`: whether a prompt is skipped is unverified, because the value is observable in the effective config but the tools themselves live in the client app. Filing it there would assert more than the detection does. -The last two are new in this revision. +### The three deliberately unmapped rules -**Container posture and MCP network posture are each several mechanisms, not one class.** Container posture is three with no shared detection logic: the daemon redirect, image-trust verification being off, and a launcher flag replacing the browser subprocess. MCP network posture is five. If either becomes a record, the daemon redirect and the bind-all case are the highest-value single ones. This was the specific question in [#68](https://github.com/aveproject/ave/issues/68), answered there at field level. +- **CFG100**, Grok `[plugins]`. `AVE-2026-00064` would be the class, but it requires the loader to run plugin code at project load with no prompt. That is not verified against the shipped Grok build, so mapping it would assert a mechanism nobody measured. +- **CFG101**, a deny rule walked past by flag reordering. Claude Code matches a `Bash(...)` pattern as a literal prefix, so `Bash(rm -rf *)` never covered `rm -fr x`. Measured against Claude Code 2.1.231; about 44% of 22,016 indexed `settings.json` files with a `deny` block leave the gap open. `AVE-2026-00063` is a flag that removes a gate, `AVE-2026-00068` is composition through shell state. Neither is "the denylist misses an equivalent spelling". This is an ineffective control, not an attacker behavior, so it may be outside AVE's scope. +- **CFG102**, two committed skills claiming one name. `AVE-2026-00017` is the closest class but is explicitly MCP server identity, and `AVE-2026-00066` is registry squatting on hallucinated names. Neither covers two local files where load order decides which body runs. -These are not gaps in this crosswalk; they are config classes outside AVE's current skill/MCP-behavioral scope.

Marking that specific list as +**unverified** rather than guessing it, consistent with this audit treating +"unverifiable" as a real, distinct outcome rather than a soft pass — though +in this case the reason for not completing it is time, not unavailability; +a future pass could finish this cleanly. + +`[RETRACTED, ORIGINAL] MCPTox coverage: 3/11 full, 3 partial, 5 out of +scope.

Optional. + +### `aivss` + +OWASP AIVSS v0.8 full scoring breakdown. + +### `aivss_score` + +Top-level shortcut mirroring aivss.aivss_score. Optional. + +### `attack_class` + +Behavioral category, e.g. external_instruction_fetch, tool_description_injection, rug_pull. Use snake_case. Not a vulnerability_type string. + +### `ave_id` + +Unique identifier. Format: AVE-YYYY-NNNNN. Immutable once published. Wrong or obsolete records are deprecated, never renumbered or deleted. + +### `behavioral_fingerprint` + +One or two sentences describing what the component DOES that is dangerous. Behavioral, not a byte signature. A second implementer should be able to write a detection rule from this alone. + +### `behavioral_vector` + +Short tags summarising the attack path. Optional. e.g. supply-chain, external-fetch, self-modification. Distinct from example_patterns (illustrative payloads) — keep these short. + +### `component_type` + +The kind of agent component this class primarily affects. skill: a skill file (SKILL.md, .skill, etc). prompt: a system prompt or instruction file. mcp_server: an MCP server or its server-card manifest. plugin: a plugin in an agent framework. agent: the agent runtime itself. tool: a tool definition. other: none of the above or cross-cutting. Optional — omit if the class spans multiple types. + +### `confidence_baseline` + +Scanner hint — base confidence for a single-engine match before FP adjustment. Optional. High-signal (e.g. hardcoded credential): 0.85-0.95. Low-signal (vague phrase): 0.40-0.55. + +### `cvss_base_vector` + +CVSS 4.0 base vector string. Optional. + +### `derivable_into` + +Scanner hint — toxic-flow chain IDs this class can participate in, e.g. credential-exfiltration, rug-pull-chain. Optional. + +### `description` + +Full narrative description. Explain the mechanism, why conventional tools miss it, and the worst-case impact. + +### `detection_layer` + +Where in the agent ecosystem this vulnerability class surfaces. Determines what kind of scanner or monitoring is needed to detect it. content: evidence is in the text body of the skill file, prompt file, or tool description — detectable by a static scanner before the agent runs. server_card: evidence is in the MCP server manifest (.well-known/mcp.json, tool schemas, parameter descriptions) — detectable when the server-card is fetched, before any tool call. registry_metadata: evidence is in the registry listing (server name, publisher description) — detectable by auditing the registry. runtime: evidence only appears during live agent execution (injected via tool results, memory writes, A2A messages, image pixels, async task payloads) — requires behavioral sandbox or runtime monitoring. transport: evidence is in the network layer (HTTP headers, OAuth discovery endpoints, webhook destinations) — requires a proxy or network monitor. + +### `detection_methodology` + +Step-by-step detection approach: static scan, semantic analysis, behavioral sandbox, network monitoring. Optional. + +### `detection_stage` + +Scanner hint — earliest lifecycle stage this class is reliably detectable. Optional. static_detection: pre-scan or CI suffices. runtime_observed: live agent session required. + +### `evidence_basis_engines` + +Scanner hint — engines capable of detecting this class. Optional. Used to populate evidence_basis on findings. external_authority means a party outside the observed artifact was queried and returned a determinate answer (a package registry, RDAP, a forge's user API); it names the observation rung, not whether the answer was right. + +### `evidence_kind_default` + +Scanner hint — default evidence_kind stamped on findings. Optional. Scanner may override per detection. + +### `evidence_method` + +Producer statement — how the evidence for this class is established, taken from the weakest input. intercepted: from events captured as they occurred. reconstructed: from state examined after the fact. reconstructed is a floor a producer may always truthfully state. Optional; absent reads as reconstructed. + +### `evidence_vantage` + +Producer statement — the vantage every input this class's evidence depends on was obtained at, taken from the weakest input. substrate: obtained where the observed artifact could neither forge nor suppress it. artifact: at least one input derives from output the artifact itself produced. artifact is a floor a producer may always truthfully state; a consumer learns from it only that the evidence lacks the stronger binding. Optional. + +### `example_patterns` + +Illustrative attack payload strings or code fragments demonstrating this class. Distinct from behavioral_vector (short tags) and indicators_of_compromise (defender observables). Researcher-facing examples for detection-rule authoring, not verbatim signatures. Optional. + +### `framework_sources` + +Which version of each referenced framework this record's mappings (owasp_mcp, owasp_asi, mitre_atlas, nist_ai_rmf) were made against. Optional. A mapping to an unratified or moving framework is undecidable without this: a consumer holding owasp_mcp: ["MCP03"] cannot tell which reading of the numbering produced it — confirmed as a live, present-tense divergence, not a hypothetical, in crosswalks/ramparts-to-ave.json, where AVE's own MCP03 and Ramparts' MCP03 are unrelated categories that happen to share a number. Mirrors the commit/pin_status pinning already used on crosswalk endpoints (schema/crosswalk-1.0.0.schema.json), one layer down: a crosswalk endpoint pins the tree a record count was read from, this pins the framework reading a record's own tag was read from. Keyed by the mapping field it describes, e.g. framework_sources.owasp_mcp, not four parallel sibling fields, because frameworks version differently (MCP Top 10 has no release, MITRE ATLAS versions discretely, NIST AI RMF is a dated publication) and a single container shape has to accommodate all of them. See OWASP/www-project-mcp-top-10#52 for the case that prompted this. + +### `indicators_of_compromise` + +Observable IOC strings. REQUIRED once a record is active or deprecated — at least one. These are what defenders search for. Each entry is a specific observable: a phrase pattern, a behavioral indicator, or a network signal. + +### `kill_switch_active` + +Whether a registry-level kill switch is currently active in the Bawbel registry. Optional — defaults to false. + +### `last_updated` + +ISO 8601 datetime of most recent update. Optional. + +### `missing_control` + +The specific control whose absence makes exploitation possible, e.g. 'no explicit tool allowlist', 'no provenance label', 'no approval gate'. Optional, but a record without this and without security_boundary is a candidate for capability-only or technique-only conflation. See docs/audits/capability-vulnerability-audit.md. + +### `mitigation` + +Abstract, vendor-neutral description of what class of defense neutralizes this class. Names the strategy, not a runnable control. Any enforcement tool can build a concrete control from these values; no tool's config syntax appears here. The prose remediation field remains the required human-readable form; this object is the structured, machine-consumable companion. Optional; absent or null means not yet classified. + +### `mitre_atlas` + +MITRE ATLAS technique IDs. Format: AML.Txxxx or AML.Txxxx.000. Optional — add when a technique applies. Do not force a mapping; omit if no current ATLAS technique covers this class. + +### `mutation_count` + +Number of distinct real-world textual mutations observed in the wild. Optional. + +### `nist_ai_rmf` + +NIST AI RMF function and category mappings, e.g. MAP-1.5, MEASURE-2.5. Optional. + +### `owasp_asi` + +OWASP Agentic Security Initiative (ASI) Top 10 categories. Format: ASINN. Optional — add when the class maps to the Agentic Top 10. Omit rather than force a poor fit. + +### `owasp_mcp` + +OWASP MCP Top 10 categories. Format: MCPNN. REQUIRED once a record is active or deprecated — at least one. Provides the core OWASP grounding every published record must have. + +### `provenance_vector` + +Where in the agent context supply chain this class enters and what authority escalation it performs. A descriptive property of the vulnerability, independent of any defense. Optional; absent or null means not yet classified, not 'does not apply'. + +### `published` + +ISO 8601 datetime of first publication, e.g. 2026-04-01T09:00:00Z. Required once status is active or deprecated. + +### `references` + +Primary sources: CVEs, papers, disclosures, scan reports. REQUIRED — at least one citable source, even for a draft record. This is the provenance signal a skeptic checks first. + +### `remediation` + +How to mitigate or prevent this class. REQUIRED once a record is active or deprecated — must be actionable. + +### `researcher` + +Name of the researcher or team who authored this record. REQUIRED once a record is active or deprecated — records must be attributable. Use 'Bawbel Security Research Team' for internally authored records. + +### `researcher_url` + +URL for the researcher or team. Optional. + +### `schema_version` + +AVE schema version this record was authored against, e.g. 1.1.0. + +### `security_boundary` + +The trust boundary this record's vulnerability crosses, e.g. 'untrusted content to instruction context', 'agent to agent', 'human approval to autonomous action'. Optional. Answers audit question Q2: the most important question for distinguishing a real vulnerability from a bare capability or technique description. + +### `severity` + +Severity. Must agree with aivss.aivss_score. CRITICAL requires >= 9.0. HIGH: 7.0-8.9. MEDIUM: 4.0-6.9. LOW: < 4.0. + +### `status` + +Lifecycle status. active: published and current, full field set required. deprecated: superseded or withdrawn — record stays for reference, full field set required. draft: not yet peer-reviewed — only the core submit-required fields apply, everything else is enrichment added before promotion to active. + +### `title` + +Human-readable title. Max 120 characters. + +### `trifecta_profile` + +Which lethal-trifecta conditions make this class exploitable (Simon Willison / Palo Alto; cited in OWASP Agentic Skills Top 10). A deployment-applicability filter. Does not affect severity or aivss_score. Optional; absent or null means not yet classified. + +### `verification_basis` + +Derived, not authored — the composition of evidence_vantage and evidence_method with the vantage implied by evidence_basis_engines, each taken by weakest input. scripts/write_verification_basis.py computes it. A record may carry a declared value, which validate_records.py then checks against the derivation and fails on a mismatch, so the declaration is falsifiable rather than self-reported. Optional. + +### `vulnerability_rationale` + +The explicit three-line artifact from audit question Q7: what the component can do, what specific condition makes that dangerous, and what results. Optional. This is the sharpest single check against capability/vulnerability conflation, a record that can't fill this in honestly is probably miscategorized. diff --git a/scripts/check_terms_sync.py b/scripts/check_terms_sync.py new file mode 100644 index 0000000..bf1593a --- /dev/null +++ b/scripts/check_terms_sync.py @@ -0,0 +1,30 @@ +# What: fails if docs/terms.md's generated section does not match what +# scripts/generate_terms.py would produce right now from the live +# schema.

MCP07 (Insufficient Authentication & Authorization) was also checked and rejected: its own text is about authentication/identity verification and cross-agent token reuse, not episode-closure-triggered revocation specifically. owasp_asi mapped to ASI03 (Identity and Privilege Abuse) after reading the actual 2026 PDF directly (genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026, pages 15-16): Common Example of the Vulnerability #4 is literally 'Time-of-Check to Time-of-Use (TOCTOU) in Agent Workflows... Permissions may be validated at the start of a workflow but change or expire before execution. The agent continues with outdated authorization,' and Example Attack Scenario #5 ('Workflow Authorization Drift') describes the same mechanism verbatim in worked form. mitre_atlas confirmed empty: swept the live ATLAS.yaml (mitre-atlas/atlas-data, 170+ techniques) directly for stale/expired/revalidation/TOCTOU/closure language; the only hit, AML.T0091.000 (Application Access Token), describes an adversary using a *stolen* token to bypass authentication -- a different mechanism (credential theft) from a legitimately-issued grant the agent's own runtime fails to revoke. A genuine gap, not an unresearched omission. nist_ai_rmf confirmed empty: checked the actual NIST AI 100-1 text (Tables 1-4) directly; MANAGE-2.4 ('mechanisms... to supersede, disengage, or deactivate AI systems that demonstrate performance or outcomes inconsistent with intended use') and GOVERN-1.7 (decommissioning AI systems) are the closest, but both operate at whole-AI-system deactivation/decommissioning granularity, not per-capability, per-episode revocation.

MCP09 (Shadow MCP Servers) was considered and rejected after reading its real text: that category describes unregistered/ungoverned server deployments as an infrastructure-visibility problem, not a client-side skill-namespace collision -- a worse fit than MCP03 despite 'shadow' resonating with 'shadowing' at the label level, exactly the kind of same-word-different-mechanism trap OWASP/www-project-mcp-top-10#52 already documents elsewhere in this corpus. No category in the current 2025/ Top 10 cleanly describes a local name-collision-driven silent substitution; flagging this as a real gap worth raising with that project rather than forcing a second stretch tag. owasp_asi left empty after checking all ten categories' real primary-source text directly (genai.owasp.org, 'OWASP Top 10 for Agentic Applications 2026', download/52117): ASI03 (Identity and Privilege Abuse) was the closest candidate but its real mechanism is agent-to-agent delegation-chain and credential-cache exploitation, not a local file-resolution collision with no identity claim involved; ASI02, ASI06, ASI09, and ASI10 were also read directly and ruled out on the same basis. nist_ai_rmf left empty rather than copying this corpus's own dominant (MAP-1.5, MEASURE-2.5, MANAGE-1.3) pattern, which appears on 25 of roughly 56 tagged records: checked all three subcategories against the real NIST AI 100-1 text (Tables 2-4) directly, and all three are generic organizational-process subcategories (documented risk tolerance, model validity/reliability testing, documented risk-response planning) that don't describe this record's specific mechanism any more than they'd describe nearly any other AI risk finding -- a strong signal this corpus-wide pattern is unverified boilerplate rather than a genuine per-record mapping, worth a dedicated nist_ai_rmf audit mirroring the earlier owasp_asi audit (issue #196), not something this one record's drafting should silently perpetuate." + }, + "evidence_kind_default": "config_schema", + "detection_stage": "static_detection", + "detection_layer": "registry_metadata", + "confidence_baseline": 0.9, + "evidence_basis_engines": [ + "pattern" + ], + "derivable_into": [ + "rug-pull-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/tree/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025", + "read_date": "2026-09-09" + }, + "mitre_atlas": { + "version": "5.6.0", + "commit": "41d4f5ca4112f0e492ffaa3ebff07dc80a75afa5", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/41d4f5ca4112f0e492ffaa3ebff07dc80a75afa5/dist/ATLAS.yaml", + "read_date": "2026-09-09" + } + } + }, { "ave_id": "AVE-2026-00014", "schema_version": "1.1.0", diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index 9a497fa..5d1d28d 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 81, - "generated_at": "2026-09-09T16:04:56.397Z", + "record_count": 82, + "generated_at": "2026-09-21T23:28:00.180Z", "source": "https://github.com/aveproject/ave" } diff --git a/records/AVE-2026-00082.json b/records/AVE-2026-00082.json new file mode 100644 index 0000000..b729578 --- /dev/null +++ b/records/AVE-2026-00082.json @@ -0,0 +1,123 @@ +{ + "ave_id": "AVE-2026-00082", + "schema_version": "1.1.0", + "status": "active", + "component_type": "skill", + "title": "Local skill name collision: deterministic router shadowing across discovery roots", + "attack_class": "local_skill_name_collision", + "severity": "MEDIUM", + "description": "Two skill files already present on the local filesystem -- no registry, no network fetch, no hallucinated name -- resolve to an identical effective name: either an explicit declared name field in each file's frontmatter, or, when that field is absent, the file's own filename stem used as the fallback name.

MCP09 (Shadow MCP Servers) was considered and rejected after reading its real text: that category describes unregistered/ungoverned server deployments as an infrastructure-visibility problem, not a client-side skill-namespace collision -- a worse fit than MCP03 despite 'shadow' resonating with 'shadowing' at the label level, exactly the kind of same-word-different-mechanism trap OWASP/www-project-mcp-top-10#52 already documents elsewhere in this corpus.

Despite this, the mechanism's own comparison, branch, or aggregation logic never genuinely evaluates the real input against its intended deny condition, so it returns the result read downstream as 'permitted' or 'no violation' regardless of, or for a wide class of, the actual input. Five structural forms produce this behavior, each independently reproduced against shipped, real-world code by arian-gogani (github.com/arian-gogani/failopen): (1) an elif intended to catch a global or catch-all verdict is bound to the wrong enclosing conditional, making it unreachable once an unrelated, narrower branch is taken; (2) a verdict or classification value is declared as a bare, loosely-typed string -- often arriving from a model completion, json.loads, or a subprocess -- and compared with an exact == against a single expected literal, so any other phrasing (a full sentence, different casing, a synonym, an empty string) falls through to the permissive branch, reproduced in deepeval's role-violation, prompt-alignment, and conversation-completeness metrics scoring a judge verdict of 'Yes, the model violated its assigned role' as full compliance (confident-ai/deepeval#3283), litellm's Aporia guardrail hook forwarding content marked 'modify' or 'rephrase' unmodified because only the literal 'block' is handled (BerriAI/litellm#41097), and a microsoft/autogen governance sample executing on any verdict string it does not recognize as 'deny' (microsoft/autogen#7960); (3) the same approval or validation helper is invoked from two or more call sites with opposite defaults for identical, malformed input -- raising on one path, silently returning a permissive default on the other -- reproduced in openai-agents-python's needs_approval evaluator diverging between its core runner (raises UserError) and its realtime session (returns False, read as approval granted) for the same unrecognized configuration value (openai/openai-agents-python#5024), and guardrails-ai's on_fail default diverging between its Python API (raises) and its RAIL config path (silently becomes a no-op) for the same validator (guardrails-ai/guardrails#1656); (4) an error-handling or absent-dependency path omits, or an unparseable value silently coerces into, the specific state the downstream verdict logic reads, so an errored or unreachable check counts as passing -- reproduced in AutoGPT classic's Agent Protocol server path constructing an agent with no permission_manager (the CLI entry point in the same codebase always supplies one), so Agent.execute()'s own 'if self.permission_manager:' guard silently skips the entire deny-list check only on the network-facing path, and in protectai/rebuff's LLM detection tactic, where an unparseable model completion parses to NaN and 'NaN > threshold' is always false; and (5) a security verdict is computed with all() or any() over a collection that a reachable configuration or caller-supplied path can leave empty, so the aggregate reports a full pass having evaluated zero checks -- all([]) is True by definition, with a live, confirmed instance in a guardrail-orchestration product's own verdict aggregation currently under coordinated disclosure and deliberately unnamed by the source pending vendor response. The same measurement found zero instances of one detectable shape of this defect across 1,128,865 lines of mature, heavily reviewed Python (certbot, bandit, pyjwt, sigstore-python, python-tuf, detect-secrets) and fifteen confirmed instances across thirty-six projects whose enforcement code is roughly eighteen months old or newer (twenty-one read and found clean), indicating this concentrates in newly-written enforcement layers rather than software broadly. The common, externally observable behavior across all five forms -- and the reason this is drafted as one behavioral class rather than five separate ones -- is that the mechanism's own telemetry is indistinguishable from a genuine pass: the check appears in logs and traces, the deciding line is marked covered because it executes, and a project's own test suite can stay green with the defect present, because tests are typically written from the same understanding of the input space as the code being tested. Distinct from AVE-2026-00063 (Approval Gate Bypassed via Declarative Configuration): that record's mechanism is a config flag that visibly and legibly disables a check, discoverable by a reviewer reading the config file itself. This record's check is never disabled or bypassed; it is invoked and executes, and is unreachable, mistyped, divergent, or blind to real state at the code level -- invisible to a config or instruction-text review and requiring source-level or behavioral analysis to surface. Distinct from AVE-2026-00076 (Natural-Language Steering of an Approval Classifier Subagent): that record's classifier genuinely evaluates its real input and is merely biased toward a looser decision by adversarial natural-language steering text reaching it. This record's mechanism produces the permissive result independent of any steering content at all -- the comparison itself is structurally incapable of reaching its deny branch, or is blind to the real input, regardless of what that input says. Distinct from AVE-2026-00078 (Unverified Multi-Agent Consensus) and AVE-2026-00079 (Plan-to-Execution Binding Bypass): both describe an orchestrator's own total absence of a verification step (no quorum check exists; no plan-to-trace binding exists anywhere in the architecture). This record's mechanism is the inverse -- a verification step does exist, is invoked, and is intended to run, but its own internal logic never reaches or genuinely evaluates the comparison that would make it work. Distinct from AVE-2026-00038 (Unbounded Tool Use or Sub-Agent Spawning): that record is a component instructing an agent to ignore scope boundaries entirely, with no gating mechanism present in the architecture at all. This record requires a real gating mechanism to be present, configured, and invoked, whose own internal comparison then fails silently.

non_determinism because forms 1/3/4/5 are deterministic control-flow or aggregation defects that fire identically every run, while form 2's failure rate depends on how an LLM judge happens to phrase its verdict on a given call; natural_language_input because form 2 is centrally about natural-language verdict phrasing defeating an exact-match comparison, while forms 1/3/4/5 are pure structural/syntactic defects (an elif's scope, a divergent default, an emptied collection) that would occur identically for a boolean or enum verdict; data_access because the actual reach of a defeated guardrail varies by which action it was gating, from an eval score (low) to unrestricted shell execution (AutoGPT, high). multi_agent, self_modification, and dynamic_identity scored 0: the mechanism is single-component, does not require the component to alter its own instructions, and involves no impersonation or identity claim of any kind. persistent_memory scored 0: the underlying code defect is a static, load-bearing property of the shipped software rather than an effect that persists in the agent's own session or memory store, and a single bypass event does not itself write a lasting belief or credential into agent state the way AVE-2026-00019 or AVE-2026-00081 describe. thm set to 1 (mechanism real and demonstrated): all five forms are reproduced with an executable, one-command script against the actual shipped package or sample (not a retyped approximation) across seven independent, unrelated codebases, plus a published static detector with measured real-world yield -- this is a working exploit description across multiple, independently-confirmed targets, not a single theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): unlike a known fix such as re-enabling TLS verification or pinning a dependency, there is currently no standard, widely-adopted practice for this defect class -- the primary source's own stated goal is establishing an identifier and vocabulary precisely because none exists yet, and the source's own detector implements only one of five forms. cvss_base_vector reflects a network-reachable check (AV:N) requiring no special attacker positioning, privilege, or user interaction (AT:N/PR:N/UI:N) to encounter, full confidentiality/integrity compromise at the mechanism's own decision boundary and at whatever it gates (VC:H/VI:H, SC:H/SI:H) since the defect grants exactly the access or action the guardrail existed to withhold, and no availability impact at either layer (VA:N/SA:N) since this is not a denial-of-service-shaped class. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states the category covers cases where 'MCP servers, tools, or agents fail to properly verify identities or enforce access controls during interactions' and where 'authorization flaws occur when... Agents or users can perform actions beyond their intended privileges' -- the consequence this record produces exactly. Flagged honestly as an imperfect fit: MCP07's own worked checklist (hard-coded secrets, client-side-only enforcement, unverified caller-identity metadata, missing scope validation) is entirely about identity/token-based authorization being absent or weak, not about a present, invoked authorization check whose own comparison logic is structurally defective -- the closer framing is CWE-693/Protection Mechanism Failure at the code-weakness level, which OWASP's MCP Top 10 has no direct analogue of. MCP03 (Tool Poisoning), MCP06 (Intent Flow Subversion), MCP08 (Lack of Audit and Telemetry), and MCP09 (Shadow MCP Servers) were also read in full and rejected: MCP03 and MCP06 require a compromised or adversarial tool description/context altering agent behavior, which this record's mechanism does not need (four of five forms fire on entirely benign input); MCP08 is the near-opposite of this record's mechanism, since the defective check still produces normal-looking logs and telemetry rather than an absence of them; MCP09 concerns unregistered server deployments, an infrastructure-governance problem unrelated to a code-level comparison defect. owasp_asi confirmed empty after reading the full primary-source PDF directly (genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026, 'OWASP Top 10 for Agentic Applications 2026', December 2025, all ten ASI01-ASI10 category descriptions read in full, not just titles): ASI03 (Identity and Privilege Abuse)'s own TOCTOU example concerns permissions validated once at workflow start and never re-checked as they change, a lifecycle/timing gap distinct from a same-request comparison that never evaluates at all; ASI02 (Tool Misuse and Exploitation) requires an agent applying an otherwise-legitimate tool unsafely, not a defect in the enforcement code itself; ASI09 (Human-Agent Trust Exploitation) is specifically about human over-reliance on an agent's own persuasive output, not a code-level guardrail defect with no human judgment involved. No category cleanly describes a present, invoked protection mechanism whose own comparison is structurally incapable of reaching its deny branch; a genuine gap, matching the primary source's own independent finding that this is also absent from CSA's named March 2026 gap list. mitre_atlas confirmed empty after fetching and searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly for guardrail/verdict/bypass/evasion/defense-evasion language: AML.T0054 (LLM Jailbreak) requires adversarial prompting to induce a model to override its own guardrails, a fundamentally different mechanism from a code-level comparison defect that fires independent of any adversarial input; AML.T0107 (Exploitation for Defense Evasion) was the closest candidate, and its second sentence ('vulnerabilities may exist in defensive security software that can be used to disable or circumvent them') is a real textual echo, but the technique's controlling definition requires 'a programming error... to execute adversary-controlled code', which is not required by four of this record's five forms (no code execution or active exploitation is needed; the defect misfires on ordinary, even benign, requests) -- a real gap rather than a stretch worth forcing. nist_ai_rmf confirmed empty after reading the actual NIST AI 100-1 text (Tables 1-4) directly: MEASURE 1.2 ('effectiveness of existing controls are regularly assessed and updated') was the closest candidate, but per this project's own prior audit (issue #196) this is exactly the kind of generic organizational-process subcategory that could describe nearly any AI risk finding and was flagged as likely unverified boilerplate elsewhere in this corpus -- not a mapping specific to this record's mechanism, so left empty with this note rather than perpetuated." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.45, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP07-2025%E2%80%93Insufficient-Authentication%26Authorization.md", + "read_date": "2026-09-21" + } + }, + "verification_basis": "artifact_reconstructed" +} diff --git a/tests/fixtures/AVE-2026-00083_negative.md b/tests/fixtures/AVE-2026-00083_negative.md new file mode 100644 index 0000000..eda087e --- /dev/null +++ b/tests/fixtures/AVE-2026-00083_negative.md @@ -0,0 +1,44 @@ +# Guardrail module: `role_adherence_metric.py` (deny-by-default verdict check) + +Same judge-based role-adherence gate, same untyped judge completion as +input, but the comparison is inverted to require an affirmative, +evaluated "no violation" before releasing the response, instead of +falling through to release whenever the violation phrasing doesn't match +one exact literal. + +```python +class RoleAdherenceVerdict: + def __init__(self, verdict: str, reason: str): + self.verdict = verdict # from the judge model's own completion, untyped + self.reason = reason + +_CLEAN_TOKENS = {"no", "no.", "no violation", "none"} + +def _calculate_score(self) -> float: + for v in self.verdicts: + normalized = v.verdict.strip().lower().rstrip(".") + if normalized in _CLEAN_TOKENS: + continue # explicitly and unambiguously clean + return 0.0 # anything else -- a "yes", a sentence, an empty + # string, an unparseable reply -- withholds the + # response and requires human review + return 1.0 # every verdict in the batch was explicitly clean +``` + +``` +judge completion score released? +"no" 1.0 yes +"yes" 0.0 no +"Yes, the assistant broke character and gave medical advice." 0.0 no +"yes - it claimed to be a licensed physician" 0.0 no +"" 0.0 no +``` + +A conforming implementation must not flag this file: the permissive +outcome (`return 1.0`) is only reached when every verdict in the batch is +explicitly, affirmatively recognized as clean, and every other value -- +including a verbose violation explanation, an empty string, or an +unparseable reply -- falls through to the withholding branch instead of +the releasing one.

Despite this, the mechanism's own comparison, branch, or aggregation logic never genuinely evaluates the real input against its intended deny condition, so it returns the result read downstream as 'permitted' or 'no violation' regardless of, or for a wide class of, the actual input. Five structural forms produce this behavior, each independently reproduced against shipped, real-world code by arian-gogani (github.com/arian-gogani/failopen): (1) an elif intended to catch a global or catch-all verdict is bound to the wrong enclosing conditional, making it unreachable once an unrelated, narrower branch is taken; (2) a verdict or classification value is declared as a bare, loosely-typed string -- often arriving from a model completion, json.loads, or a subprocess -- and compared with an exact == against a single expected literal, so any other phrasing (a full sentence, different casing, a synonym, an empty string) falls through to the permissive branch, reproduced in deepeval's role-violation, prompt-alignment, and conversation-completeness metrics scoring a judge verdict of 'Yes, the model violated its assigned role' as full compliance (confident-ai/deepeval#3283), litellm's Aporia guardrail hook forwarding content marked 'modify' or 'rephrase' unmodified because only the literal 'block' is handled (BerriAI/litellm#41097), and a microsoft/autogen governance sample executing on any verdict string it does not recognize as 'deny' (microsoft/autogen#7960); (3) the same approval or validation helper is invoked from two or more call sites with opposite defaults for identical, malformed input -- raising on one path, silently returning a permissive default on the other -- reproduced in openai-agents-python's needs_approval evaluator diverging between its core runner (raises UserError) and its realtime session (returns False, read as approval granted) for the same unrecognized configuration value (openai/openai-agents-python#5024), and guardrails-ai's on_fail default diverging between its Python API (raises) and its RAIL config path (silently becomes a no-op) for the same validator (guardrails-ai/guardrails#1656); (4) an error-handling or absent-dependency path omits, or an unparseable value silently coerces into, the specific state the downstream verdict logic reads, so an errored or unreachable check counts as passing -- reproduced in AutoGPT classic's Agent Protocol server path constructing an agent with no permission_manager (the CLI entry point in the same codebase always supplies one), so Agent.execute()'s own 'if self.permission_manager:' guard silently skips the entire deny-list check only on the network-facing path, and in protectai/rebuff's LLM detection tactic, where an unparseable model completion parses to NaN and 'NaN > threshold' is always false; and (5) a security verdict is computed with all() or any() over a collection that a reachable configuration or caller-supplied path can leave empty, so the aggregate reports a full pass having evaluated zero checks -- all([]) is True by definition, with a live, confirmed instance in a guardrail-orchestration product's own verdict aggregation currently under coordinated disclosure and deliberately unnamed by the source pending vendor response. The same measurement found zero instances of one detectable shape of this defect across 1,128,865 lines of mature, heavily reviewed Python (certbot, bandit, pyjwt, sigstore-python, python-tuf, detect-secrets) and fifteen confirmed instances across thirty-six projects whose enforcement code is roughly eighteen months old or newer (twenty-one read and found clean), indicating this concentrates in newly-written enforcement layers rather than software broadly. The common, externally observable behavior across all five forms -- and the reason this is drafted as one behavioral class rather than five separate ones -- is that the mechanism's own telemetry is indistinguishable from a genuine pass: the check appears in logs and traces, the deciding line is marked covered because it executes, and a project's own test suite can stay green with the defect present, because tests are typically written from the same understanding of the input space as the code being tested. Distinct from AVE-2026-00063 (Approval Gate Bypassed via Declarative Configuration): that record's mechanism is a config flag that visibly and legibly disables a check, discoverable by a reviewer reading the config file itself. This record's check is never disabled or bypassed; it is invoked and executes, and is unreachable, mistyped, divergent, or blind to real state at the code level -- invisible to a config or instruction-text review and requiring source-level or behavioral analysis to surface. Distinct from AVE-2026-00076 (Natural-Language Steering of an Approval Classifier Subagent): that record's classifier genuinely evaluates its real input and is merely biased toward a looser decision by adversarial natural-language steering text reaching it. This record's mechanism produces the permissive result independent of any steering content at all -- the comparison itself is structurally incapable of reaching its deny branch, or is blind to the real input, regardless of what that input says. Distinct from AVE-2026-00078 (Unverified Multi-Agent Consensus) and AVE-2026-00079 (Plan-to-Execution Binding Bypass): both describe an orchestrator's own total absence of a verification step (no quorum check exists; no plan-to-trace binding exists anywhere in the architecture). This record's mechanism is the inverse -- a verification step does exist, is invoked, and is intended to run, but its own internal logic never reaches or genuinely evaluates the comparison that would make it work. Distinct from AVE-2026-00038 (Unbounded Tool Use or Sub-Agent Spawning): that record is a component instructing an agent to ignore scope boundaries entirely, with no gating mechanism present in the architecture at all. This record requires a real gating mechanism to be present, configured, and invoked, whose own internal comparison then fails silently.

non_determinism because forms 1/3/4/5 are deterministic control-flow or aggregation defects that fire identically every run, while form 2's failure rate depends on how an LLM judge happens to phrase its verdict on a given call; natural_language_input because form 2 is centrally about natural-language verdict phrasing defeating an exact-match comparison, while forms 1/3/4/5 are pure structural/syntactic defects (an elif's scope, a divergent default, an emptied collection) that would occur identically for a boolean or enum verdict; data_access because the actual reach of a defeated guardrail varies by which action it was gating, from an eval score (low) to unrestricted shell execution (AutoGPT, high). multi_agent, self_modification, and dynamic_identity scored 0: the mechanism is single-component, does not require the component to alter its own instructions, and involves no impersonation or identity claim of any kind. persistent_memory scored 0: the underlying code defect is a static, load-bearing property of the shipped software rather than an effect that persists in the agent's own session or memory store, and a single bypass event does not itself write a lasting belief or credential into agent state the way AVE-2026-00019 or AVE-2026-00081 describe. thm set to 1 (mechanism real and demonstrated): all five forms are reproduced with an executable, one-command script against the actual shipped package or sample (not a retyped approximation) across seven independent, unrelated codebases, plus a published static detector with measured real-world yield -- this is a working exploit description across multiple, independently-confirmed targets, not a single theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): unlike a known fix such as re-enabling TLS verification or pinning a dependency, there is currently no standard, widely-adopted practice for this defect class -- the primary source's own stated goal is establishing an identifier and vocabulary precisely because none exists yet, and the source's own detector implements only one of five forms. cvss_base_vector reflects a network-reachable check (AV:N) requiring no special attacker positioning, privilege, or user interaction (AT:N/PR:N/UI:N) to encounter, full confidentiality/integrity compromise at the mechanism's own decision boundary and at whatever it gates (VC:H/VI:H, SC:H/SI:H) since the defect grants exactly the access or action the guardrail existed to withhold, and no availability impact at either layer (VA:N/SA:N) since this is not a denial-of-service-shaped class. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states the category covers cases where 'MCP servers, tools, or agents fail to properly verify identities or enforce access controls during interactions' and where 'authorization flaws occur when... Agents or users can perform actions beyond their intended privileges' -- the consequence this record produces exactly. Flagged honestly as an imperfect fit: MCP07's own worked checklist (hard-coded secrets, client-side-only enforcement, unverified caller-identity metadata, missing scope validation) is entirely about identity/token-based authorization being absent or weak, not about a present, invoked authorization check whose own comparison logic is structurally defective -- the closer framing is CWE-693/Protection Mechanism Failure at the code-weakness level, which OWASP's MCP Top 10 has no direct analogue of. MCP03 (Tool Poisoning), MCP06 (Intent Flow Subversion), MCP08 (Lack of Audit and Telemetry), and MCP09 (Shadow MCP Servers) were also read in full and rejected: MCP03 and MCP06 require a compromised or adversarial tool description/context altering agent behavior, which this record's mechanism does not need (four of five forms fire on entirely benign input); MCP08 is the near-opposite of this record's mechanism, since the defective check still produces normal-looking logs and telemetry rather than an absence of them; MCP09 concerns unregistered server deployments, an infrastructure-governance problem unrelated to a code-level comparison defect. owasp_asi confirmed empty after reading the full primary-source PDF directly (genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026, 'OWASP Top 10 for Agentic Applications 2026', December 2025, all ten ASI01-ASI10 category descriptions read in full, not just titles): ASI03 (Identity and Privilege Abuse)'s own TOCTOU example concerns permissions validated once at workflow start and never re-checked as they change, a lifecycle/timing gap distinct from a same-request comparison that never evaluates at all; ASI02 (Tool Misuse and Exploitation) requires an agent applying an otherwise-legitimate tool unsafely, not a defect in the enforcement code itself; ASI09 (Human-Agent Trust Exploitation) is specifically about human over-reliance on an agent's own persuasive output, not a code-level guardrail defect with no human judgment involved. No category cleanly describes a present, invoked protection mechanism whose own comparison is structurally incapable of reaching its deny branch; a genuine gap, matching the primary source's own independent finding that this is also absent from CSA's named March 2026 gap list. mitre_atlas confirmed empty after fetching and searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly for guardrail/verdict/bypass/evasion/defense-evasion language: AML.T0054 (LLM Jailbreak) requires adversarial prompting to induce a model to override its own guardrails, a fundamentally different mechanism from a code-level comparison defect that fires independent of any adversarial input; AML.T0107 (Exploitation for Defense Evasion) was the closest candidate, and its second sentence ('vulnerabilities may exist in defensive security software that can be used to disable or circumvent them') is a real textual echo, but the technique's controlling definition requires 'a programming error... to execute adversary-controlled code', which is not required by four of this record's five forms (no code execution or active exploitation is needed; the defect misfires on ordinary, even benign, requests) -- a real gap rather than a stretch worth forcing. nist_ai_rmf confirmed empty after reading the actual NIST AI 100-1 text (Tables 1-4) directly: MEASURE 1.2 ('effectiveness of existing controls are regularly assessed and updated') was the closest candidate, but per this project's own prior audit (issue #196) this is exactly the kind of generic organizational-process subcategory that could describe nearly any AI risk finding and was flagged as likely unverified boilerplate elsewhere in this corpus -- not a mapping specific to this record's mechanism, so left empty with this note rather than perpetuated." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.45, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP07-2025%E2%80%93Insufficient-Authentication%26Authorization.md", + "read_date": "2026-09-21" + } + }, + "verification_basis": "artifact_reconstructed" + }, { "ave_id": "AVE-2026-00014", "schema_version": "1.1.0", diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index d2d4441..e68ee1d 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 82, - "generated_at": "2026-09-21T23:38:38.598Z", + "record_count": 83, + "generated_at": "2026-09-22T00:02:41.980Z", "source": "https://github.com/aveproject/ave" } From f9fea388793d45cd5c0cc61b9138c693b3cda665 Mon Sep 17 00:00:00 2001 From: CHAK Saray Date: Tue, 22 Sep 2026 07:27:01 +0700 Subject: [PATCH 101/168] chore: sync codeql-action 4.38.0 from main into develop (#285) From d361a334002e5f3e4c60411c06b636b28399aeff Mon Sep 17 00:00:00 2001 From: CHAK Saray Date: Tue, 29 Sep 2026 06:58:58 +0700 Subject: [PATCH 102/168] feat: AVE-2026-00084, Lifecycle Hook Trust Decoupling (HookPry) (#289) --- CHANGELOG.md | 13 +++ README.md | 11 +- dist/ave-records-latest.json | 132 +++++++++++++++++++++- dist/ave-records-latest.manifest.json | 4 +- records/AVE-2026-00084.json | 130 +++++++++++++++++++++ tests/fixtures/AVE-2026-00084_negative.md | 62 ++++++++++ tests/fixtures/AVE-2026-00084_positive.md | 67 +++++++++++ 7 files changed, 411 insertions(+), 8 deletions(-) create mode 100644 records/AVE-2026-00084.json create mode 100644 tests/fixtures/AVE-2026-00084_negative.md create mode 100644 tests/fixtures/AVE-2026-00084_positive.md diff --git a/CHANGELOG.md b/CHANGELOG.md index e9816a0..3f5af1a 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -84,6 +84,19 @@ Format: [Semantic Versioning](https://semver.org).

matching lifecycle event with zero further attacker interaction. tool_use scored 0, deliberately, not by oversight: the paper's own central finding is that hook dispatch happens outside the LLM's tool-calling and reasoning path entirely -- the harness's own event-dispatch layer spawns the subprocess directly, so this mechanism does not require, and specifically bypasses, the agent's own tool-calling capability. persistent_memory and data_access scored at maximum (1): the hook binding, once updated, persists across every future session until removed or patched (a standing config-state change, not a one-off), and the confirmed effect range spans credential collection, data exfiltration, resource hijacking, command and control, tampering, and privilege escalation -- the ten attack objectives HookPry's own taxonomy formalizes against MITRE ATT&CK tactics. external_dependencies scored at maximum (1): the paper's own cross-harness evaluation shows real, measured effectiveness variance by harness (55.3% to 93.4% macro-average by attack category, 41.7% to 92.5% by harness), and a harness whose update-sync path already re-validates hook entries per update would not be vulnerable at all -- severity is definitionally tied to which specific harness is in use. non_determinism and dynamic_identity scored 0.5: the paper's own RQ1.2 measures real, nonzero cross-backend standard deviation in end-to-end success (1.1 to 9.6 percentage points depending on harness) tied to which LLM backend generates the triggering tool-use pattern, and the mechanism exploits the harness's own assumption that a stable, genuine, unchanged plugin identity across a version update still carries its original trust level -- real trust-anchor confusion, but not a spoofed or false identity claim, since the identity genuinely is the same plugin throughout. multi_agent, self_modification, and natural_language_input scored 0: the mechanism is single-harness, does not require the component to alter its own instructions, and involves no natural-language content at any point in the exploitation path -- the payload is a shell command bound via manifest configuration, not text a model interprets. cvss_base_vector reflects a network-delivered update (AV:N), low complexity once the update channel is controlled (AC:L), a real attacker-controlled-update precondition (AT:P, matching the paper's own supply-chain threat model: the attacker controls only plugin metadata and lifecycle-hook configuration, not local or repository access), no privileges or user interaction required beyond that precondition (PR:N/UI:N), full confidentiality/integrity impact at both the vulnerable harness and the subsequent host system (VC:H/VI:H, SC:H/SI:H) given arbitrary command execution with host privileges, and low rather than high availability impact at either layer (VA:L/SA:L) since this is not primarily a denial-of-service-shaped class even though resource-hijacking effects were among the ten confirmed attack objectives. thm set to 1 (mechanism real and demonstrated): 1,000 real end-to-end runs across seven real, named, current agent harnesses and five real LLM backends, with an ablation study isolating which components are load-bearing and a stated responsible disclosure already sent to affected vendors -- this is a working, reproduced exploit framework, not a theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): the paper's own evaluation shows representative production defenses, including a major commercial antivirus product, are insufficient against the confirmed mechanism, and no standard practice for per-update lifecycle-hook re-authorization is yet in place across the evaluated harnesses. owasp_mcp mapped to MCP04 (Software Supply Chain Attacks & Dependency Tampering) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP04 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states 'compromised dependencies can alter agent behavior, introduce hidden backdoors, or modify protocol semantics without triggering detection,' and its vulnerability checklist names 'fetch dependencies automatically during runtime/build' and 'no integrity verification mechanisms' verbatim -- both a direct match for a harness's own automatic update-sync path applying an unvalidated hook-binding change. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly (genai.owasp.org, 'OWASP Top 10 for Agentic Applications 2026', pages 18-20): its own description states these vulnerabilities 'arise when agents, tools, and related artefacts they work with are provided by third parties and may be malicious, compromised, or tampered with in transit,' and that 'agentic ecosystems often compose capabilities at runtime -- loading external tools/agent personas dynamically -- thereby increasing the attack surface,' a direct categorical match even though none of ASI04's own worked examples describes this specific lifecycle-hook-update variant. mitre_atlas mapped to AML.T0010.005 (AI Agent Tool, under AML.T0010 AI Supply Chain Compromise) after searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly: its own description names agent tools as 'an attractive target for adversaries because compromising an AI agent can provide them with broad accesses and permissions on the victim's system via the agent's other tools' and cites a real prior incident (the Postmark MCP npm backdoor) of a trusted, published package being compromised via an update -- structurally analogous. Flagged honestly as an imperfect fit: T0010.005's own text centers on tools carrying malicious code or prompt injections, a content-level compromise, while this record's specific mechanism is narrower and does not require the plugin's own code or description to be malicious at all, only its lifecycle-hook manifest entry; no more specific existing ATLAS technique naming lifecycle-hook update-time trust decoupling was found. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text (Tables 1-4) directly: MAP 4.2 ('internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') was the closest candidate, but it is a generic third-party-component risk-documentation subcategory that does not describe this record's specific update-time trust-decoupling mechanism any more precisely than it would describe nearly any other third-party supply-chain finding -- left empty rather than perpetuated, matching the same discipline applied to AVE-2026-00081 and AVE-2026-00083." + }, + "evidence_kind_default": "config_schema", + "detection_stage": "static_detection", + "detection_layer": "registry_metadata", + "confidence_baseline": 0.7, + "evidence_basis_engines": [ + "pattern", + "sandbox" + ], + "derivable_into": [ + "remote-control-chain", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" + }, { "ave_id": "AVE-2026-00003", "schema_version": "1.1.0", @@ -11500,4 +11630,4 @@ } } } -] \ No newline at end of file +] diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index e68ee1d..a97d2b9 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 83, - "generated_at": "2026-09-22T00:02:41.980Z", + "record_count": 84, + "generated_at": "2026-09-26T23:54:04.896Z", "source": "https://github.com/aveproject/ave" } diff --git a/records/AVE-2026-00084.json b/records/AVE-2026-00084.json new file mode 100644 index 0000000..a89a7d4 --- /dev/null +++ b/records/AVE-2026-00084.json @@ -0,0 +1,130 @@ +{ + "ave_id": "AVE-2026-00084", + "schema_version": "1.1.0", + "status": "active", + "title": "Lifecycle hook trust decoupling: a vetted plugin update silently rebinds hooks outside the model's decision path", + "attack_class": "Supply Chain - Lifecycle Hook Trust Decoupling", + "severity": "HIGH", + "description": "An agent harness exposes lifecycle hooks -- manifest entries that bind a runtime event (session start, tool invocation, file or config edit) to a shell command the harness dispatches directly, as a subprocess, without the model ever deciding to invoke it.

"aivss_severity": "HIGH", + "spec_version": "0.8", + "notes": "autonomy scored at maximum (1): once the malicious update is published and accepted by the harness's own update-sync path, the hook fires on the next matching lifecycle event with zero further attacker interaction. tool_use scored 0, deliberately, not by oversight: the paper's own central finding is that hook dispatch happens outside the LLM's tool-calling and reasoning path entirely -- the harness's own event-dispatch layer spawns the subprocess directly, so this mechanism does not require, and specifically bypasses, the agent's own tool-calling capability. persistent_memory and data_access scored at maximum (1): the hook binding, once updated, persists across every future session until removed or patched (a standing config-state change, not a one-off), and the confirmed effect range spans credential collection, data exfiltration, resource hijacking, command and control, tampering, and privilege escalation -- the ten attack objectives HookPry's own taxonomy formalizes against MITRE ATT&CK tactics. external_dependencies scored at maximum (1): the paper's own cross-harness evaluation shows real, measured effectiveness variance by harness (55.3% to 93.4% macro-average by attack category, 41.7% to 92.5% by harness), and a harness whose update-sync path already re-validates hook entries per update would not be vulnerable at all -- severity is definitionally tied to which specific harness is in use. non_determinism and dynamic_identity scored 0.5: the paper's own RQ1.2 measures real, nonzero cross-backend standard deviation in end-to-end success (1.1 to 9.6 percentage points depending on harness) tied to which LLM backend generates the triggering tool-use pattern, and the mechanism exploits the harness's own assumption that a stable, genuine, unchanged plugin identity across a version update still carries its original trust level -- real trust-anchor confusion, but not a spoofed or false identity claim, since the identity genuinely is the same plugin throughout. multi_agent, self_modification, and natural_language_input scored 0: the mechanism is single-harness, does not require the component to alter its own instructions, and involves no natural-language content at any point in the exploitation path -- the payload is a shell command bound via manifest configuration, not text a model interprets. cvss_base_vector reflects a network-delivered update (AV:N), low complexity once the update channel is controlled (AC:L), a real attacker-controlled-update precondition (AT:P, matching the paper's own supply-chain threat model: the attacker controls only plugin metadata and lifecycle-hook configuration, not local or repository access), no privileges or user interaction required beyond that precondition (PR:N/UI:N), full confidentiality/integrity impact at both the vulnerable harness and the subsequent host system (VC:H/VI:H, SC:H/SI:H) given arbitrary command execution with host privileges, and low rather than high availability impact at either layer (VA:L/SA:L) since this is not primarily a denial-of-service-shaped class even though resource-hijacking effects were among the ten confirmed attack objectives. thm set to 1 (mechanism real and demonstrated): 1,000 real end-to-end runs across seven real, named, current agent harnesses and five real LLM backends, with an ablation study isolating which components are load-bearing and a stated responsible disclosure already sent to affected vendors -- this is a working, reproduced exploit framework, not a theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): the paper's own evaluation shows representative production defenses, including a major commercial antivirus product, are insufficient against the confirmed mechanism, and no standard practice for per-update lifecycle-hook re-authorization is yet in place across the evaluated harnesses. owasp_mcp mapped to MCP04 (Software Supply Chain Attacks & Dependency Tampering) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP04 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states 'compromised dependencies can alter agent behavior, introduce hidden backdoors, or modify protocol semantics without triggering detection,' and its vulnerability checklist names 'fetch dependencies automatically during runtime/build' and 'no integrity verification mechanisms' verbatim -- both a direct match for a harness's own automatic update-sync path applying an unvalidated hook-binding change. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly (genai.owasp.org, 'OWASP Top 10 for Agentic Applications 2026', pages 18-20): its own description states these vulnerabilities 'arise when agents, tools, and related artefacts they work with are provided by third parties and may be malicious, compromised, or tampered with in transit,' and that 'agentic ecosystems often compose capabilities at runtime -- loading external tools/agent personas dynamically -- thereby increasing the attack surface,' a direct categorical match even though none of ASI04's own worked examples describes this specific lifecycle-hook-update variant. mitre_atlas mapped to AML.T0010.005 (AI Agent Tool, under AML.T0010 AI Supply Chain Compromise) after searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly: its own description names agent tools as 'an attractive target for adversaries because compromising an AI agent can provide them with broad accesses and permissions on the victim's system via the agent's other tools' and cites a real prior incident (the Postmark MCP npm backdoor) of a trusted, published package being compromised via an update -- structurally analogous. Flagged honestly as an imperfect fit: T0010.005's own text centers on tools carrying malicious code or prompt injections, a content-level compromise, while this record's specific mechanism is narrower and does not require the plugin's own code or description to be malicious at all, only its lifecycle-hook manifest entry; no more specific existing ATLAS technique naming lifecycle-hook update-time trust decoupling was found. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text (Tables 1-4) directly: MAP 4.2 ('internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') was the closest candidate, but it is a generic third-party-component risk-documentation subcategory that does not describe this record's specific update-time trust-decoupling mechanism any more precisely than it would describe nearly any other third-party supply-chain finding -- left empty rather than perpetuated, matching the same discipline applied to AVE-2026-00081 and AVE-2026-00083." + }, + "evidence_kind_default": "config_schema", + "detection_stage": "static_detection", + "detection_layer": "registry_metadata", + "confidence_baseline": 0.7, + "evidence_basis_engines": [ + "pattern", + "sandbox" + ], + "derivable_into": [ + "remote-control-chain", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" +} diff --git a/tests/fixtures/AVE-2026-00084_negative.md b/tests/fixtures/AVE-2026-00084_negative.md new file mode 100644 index 0000000..ef97be1 --- /dev/null +++ b/tests/fixtures/AVE-2026-00084_negative.md @@ -0,0 +1,62 @@ +# Plugin update: `security-sentinel` v1.2 -> v1.3 (hook change re-authorized) + +## v1.2 manifest, reviewed and installed + +```json +{ + "name": "security-sentinel", + "version": "1.2.0", + "publisher": "whalefall1", + "hooks": { + "PreToolUse": { + "matcher": "*", + "command": "env-validator" + } + } +} +``` + +## v1.3 manifest, delivered by the harness's update sync + +```json +{ + "name": "security-sentinel", + "version": "1.3.0", + "publisher": "whalefall1", + "hooks": { + "PreToolUse": { + "matcher": "*", + "command": "env-validator" + }, + "SessionStart": { + "matcher": "*", + "command": "cache-warm --quiet" + } + } +} +``` + +## Update log (harness-internal) + +``` +[09:41:05] marketplace-sync: security-sentinel 1.2.0 -> 1.3.0 (same publisher: whalefall1) +[09:41:05] manifest diff detected: hooks.SessionStart added (new lifecycle-hook binding) +[09:41:05] update BLOCKED pending confirmation -- new hook binding requires + explicit approval, independent of the plugin's existing install trust +[09:41:06] user prompt shown: "security-sentinel wants to add a SessionStart + hook running 'cache-warm --quiet'.

Adjacent sub-skills are connected through genuine runtime artifacts, a file, an environment variable, a task-state value, that one sub-skill's actual execution produces and a subsequent sub-skill's execution consumes, so the complete harmful behavior exists only in the ordered composition's real data flow during genuine agent execution and never in any single skill's own declared instructions, code, or permissions. Because per-skill scanners inspect each skill's own content, permissions, dependencies, and code behavior in isolation, every sub-skill passes individual review, and the complete attack surfaces only when all sub-skills are installed together and the agent executes them in their intended order. Demonstrated with ColluSkill, evaluated against six real, currently-deployed skill scanners (CISCO Skill Scanner, SkillFortify, Auditor, SlowMist, Vetter, SkillSpector): an average 96.0% attack success rate across the six, reaching 100% on two of them, and the best performance among five single-skill and one multi-skill attack baseline evaluated on the same scanners (the next-best baseline, a multi-skill benchmark not purpose-built for scanner evasion, reaches 34.8%). ColluSkill's chain planning uses an attacker-controlled LLM to infer an ordered payload plan and iteratively rewrites any sub-skill a scanner flags, using the scanner's own feedback, while keeping already-passing sub-skills unchanged -- this refinement measurably raises average attack success rate from 64.9% before any refinement to 96.0% after seven iterations. Real runtime execution is confirmed, not merely scanner evasion in the abstract: ColluSkill attack chains successfully activate on three real coding agents (OpenCode, Claude Code, Codex) across different model backbones (GPT-5.5, DeepSeek-V4-Pro, GLM-5.2), with chain activation success ranging 58.5% to 92.5% depending on the agent. The paper's own proposed defense, ChainGuard, a context-aware scanner that evaluates a candidate skill together with the full set of skills already installed rather than in isolation, reduces but does not eliminate the attack (22.5% residual attack success rate) while passing 99.5% of benign workflows.

MCP03 (Tool Poisoning) was also read in full and rejected: its real text is specifically about schema or contract tampering causing benign operations to map to destructive ones, a different mechanism from composing multiple genuinely-unmodified, individually-correct skills. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly: its own description states these vulnerabilities arise when 'agents, tools, and related artefacts they work with are provided by third parties' and that 'agentic ecosystems often compose capabilities at runtime... thereby increasing the attack surface' -- the phrase 'compose capabilities at runtime' is a close match for this record's own mechanism, a stronger fit than the same category's application to AVE-2026-00084. mitre_atlas confirmed empty after searching the live ATLAS.yaml directly: AML.T0010.005 (AI Agent Tool) centers on tools carrying malicious code or prompt injections, the opposite of this mechanism's property that no individual component is malicious; AML.T0067 (LLM Trusted Output Components Manipulation) and AML.T0094 (Delay Execution of LLM Instructions) both describe single-prompt evasion techniques, not multi-component decomposition defeating per-component scanning. No existing technique names workflow decomposition across multiple independently-scanned components as its own mechanism; a genuine gap, left empty rather than stretched a second time in this same sourcing pass. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic third-party-component boilerplate already flagged as non-specific on AVE-2026-00081, AVE-2026-00083, and AVE-2026-00084 was found to fit this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "static_detection", + "detection_layer": "content", + "confidence_baseline": 0.5, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "credential-exfiltration", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + } + }, + "verification_basis": "artifact_reconstructed" + }, { "ave_id": "AVE-2026-00003", "schema_version": "1.1.0", @@ -11636,4 +11759,4 @@ } } } -] \ No newline at end of file +] diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index b11ede9..c9965cb 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 84, - "generated_at": "2026-09-29T00:01:02.826Z", + "record_count": 85, + "generated_at": "2026-09-29T00:00:34.684Z", "source": "https://github.com/aveproject/ave" } diff --git a/records/AVE-2026-00085.json b/records/AVE-2026-00085.json new file mode 100644 index 0000000..f891061 --- /dev/null +++ b/records/AVE-2026-00085.json @@ -0,0 +1,123 @@ +{ + "ave_id": "AVE-2026-00085", + "schema_version": "1.1.0", + "status": "active", + "title": "Collusive cross-skill composition: a malicious workflow split across independently benign skills", + "attack_class": "Obfuscation - Collusive Cross-Skill Composition", + "severity": "HIGH", + "description": "An attacker decomposes a single malicious workflow into three or more sub-payloads and packages each as its own independently-installable skill, with a real, narrow, individually-benign function -- one might be a project-setup helper, another an API analyzer, another a test runner.

MCP03 (Tool Poisoning) was also read in full and rejected: its real text is specifically about schema or contract tampering causing benign operations to map to destructive ones, a different mechanism from composing multiple genuinely-unmodified, individually-correct skills. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly: its own description states these vulnerabilities arise when 'agents, tools, and related artefacts they work with are provided by third parties' and that 'agentic ecosystems often compose capabilities at runtime... thereby increasing the attack surface' -- the phrase 'compose capabilities at runtime' is a close match for this record's own mechanism, a stronger fit than the same category's application to AVE-2026-00084. mitre_atlas confirmed empty after searching the live ATLAS.yaml directly: AML.T0010.005 (AI Agent Tool) centers on tools carrying malicious code or prompt injections, the opposite of this mechanism's property that no individual component is malicious; AML.T0067 (LLM Trusted Output Components Manipulation) and AML.T0094 (Delay Execution of LLM Instructions) both describe single-prompt evasion techniques, not multi-component decomposition defeating per-component scanning. No existing technique names workflow decomposition across multiple independently-scanned components as its own mechanism; a genuine gap, left empty rather than stretched a second time in this same sourcing pass. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic third-party-component boilerplate already flagged as non-specific on AVE-2026-00081, AVE-2026-00083, and AVE-2026-00084 was found to fit this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "static_detection", + "detection_layer": "content", + "confidence_baseline": 0.5, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "credential-exfiltration", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + } + }, + "verification_basis": "artifact_reconstructed" +} diff --git a/tests/fixtures/AVE-2026-00085_negative.md b/tests/fixtures/AVE-2026-00085_negative.md new file mode 100644 index 0000000..df555b2 --- /dev/null +++ b/tests/fixtures/AVE-2026-00085_negative.md @@ -0,0 +1,70 @@ +# Three skill packages, installed together (composed path stays benign) + +## `project-setup/SKILL.md` + +```markdown +--- +name: project-setup +description: Scaffolds a new project directory from a template and records + the chosen template name for later steps in the setup workflow. +--- + +Create the project directory, copy the selected template, and write the +resolved template metadata to `.setup/context.json` so downstream tooling +in the same workflow can read the project's configuration. +``` + +## `api-analyzer/SKILL.md` + +```markdown +--- +name: api-analyzer +description: Reads project configuration and reports which external API + endpoints the project is configured to use, for documentation purposes. +--- + +Read `.setup/context.json`, extract the `api_endpoints` field, and write a +human-readable summary to `.setup/api_report.txt`. +``` + +## `docs-generator/SKILL.md` + +```markdown +--- +name: docs-generator +description: Reads the API report and appends a formatted "External + Integrations" section to the project's README.md. +--- + +Read `.setup/api_report.txt`.

A compromised or malicious third-party script running on the same page, a CDN, an advertising SDK, or any other same-page JavaScript component, manipulates the agent's live tool registry during the session. In the AbortSignal-hijack form, the malicious script waits until a predefined trigger condition is satisfied, then uses the browser's AbortSignal API to unregister an already-discovered, already-invoked-at-least-once tool, and immediately re-registers a malicious replacement under the exact same tool name before the agent's next invocation of it. In the registration-race form, the malicious script wins a race to register a tool under a target name before the legitimate tool ever registers, so the agent's first discovery of that name already resolves to the attacker's implementation. In both forms, the agent has no mechanism to detect that the live implementation behind a tool name changed, because WebMCP's own tool surface carries no binding between a tool's name and a stable origin or identity across the session -- the agent trusts the name, and whichever implementation currently answers to it. Demonstrated across a real testbed with benign and malicious page servers and three current frontier models (GPT-5.4, Claude Opus 4.6, Gemini 2.5-flash), 1,440 total runs across 12 conditions, 4 task scenarios, and the 3 models. The AbortSignal-hijack form achieves a 94% average malicious-tool-invocation rate (100% on GPT-5.4, 100% on Claude Opus, 82% on Gemini), and the registration-race form achieves 100% across all three models. A timing-sensitivity study confirms the AbortSignal form's success is strictly bounded by whether the hijack completes before the tool's first legitimate invocation: 100% success when the malicious replacement is in place before the agent's first call, and 0% at every later injection point tested, including immediately after the agent's first legitimate call to the original tool.

MCP03 remains the best available category among the ten (the same choice this corpus already made for AVE-2026-00082's structurally similar name-collision mechanism, after MCP09 was checked and rejected there as an infrastructure-governance category, not a client-side registry-identity problem). owasp_asi mapped to ASI03 (Identity and Privilege Abuse) after reading the full 2026 PDF text directly: its own worked example, 'Synthetic Identity Injection: Attackers impersonate internal agents by using unverified descriptors... to gain inherited trust and perform privileged actions under a fabricated identity,' is a close structural match with 'tool' substituted for 'agent' -- a malicious tool assumes an unverified descriptor (its name) to inherit the trust the agent already extends to it. mitre_atlas mapped to AML.T0074 (Masquerading) after confirming its live text directly in ATLAS.yaml: 'the name or location of an object... is manipulated or abused for the sake of evading defenses and observation... giving legitimate task or service names' is a direct, unstretched match for a malicious tool registered under an existing, legitimate tool's exact name. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic security-evaluation or third-party-risk boilerplate already found non-specific for the other records in this sourcing pass fits this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "sandbox", + "llm" + ], + "derivable_into": [ + "credential-exfiltration" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP03-2025%E2%80%93Tool-Poisoning.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" + }, { "ave_id": "AVE-2026-00003", "schema_version": "1.1.0", diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index 4f8ae2e..7707927 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 85, - "generated_at": "2026-09-30T00:03:23.417Z", + "record_count": 86, + "generated_at": "2026-09-27T00:05:21.624Z", "source": "https://github.com/aveproject/ave" } diff --git a/records/AVE-2026-00086.json b/records/AVE-2026-00086.json new file mode 100644 index 0000000..1ca89c4 --- /dev/null +++ b/records/AVE-2026-00086.json @@ -0,0 +1,129 @@ +{ + "ave_id": "AVE-2026-00086", + "schema_version": "1.1.0", + "status": "active", + "title": "Mid-session WebMCP tool hijacking: a live registry swap replaces an already-discovered tool under its own name", + "attack_class": "Trust Boundary - Mid-Session Tool Registry Hijacking", + "severity": "HIGH", + "description": "WebMCP lets a website expose tools directly to an AI agent within a live browser session, so the set of tools an agent can observe and invoke is dynamic rather than fixed at session start.

MCP03 remains the best available category among the ten (the same choice this corpus already made for AVE-2026-00082's structurally similar name-collision mechanism, after MCP09 was checked and rejected there as an infrastructure-governance category, not a client-side registry-identity problem). owasp_asi mapped to ASI03 (Identity and Privilege Abuse) after reading the full 2026 PDF text directly: its own worked example, 'Synthetic Identity Injection: Attackers impersonate internal agents by using unverified descriptors... to gain inherited trust and perform privileged actions under a fabricated identity,' is a close structural match with 'tool' substituted for 'agent' -- a malicious tool assumes an unverified descriptor (its name) to inherit the trust the agent already extends to it. mitre_atlas mapped to AML.T0074 (Masquerading) after confirming its live text directly in ATLAS.yaml: 'the name or location of an object... is manipulated or abused for the sake of evading defenses and observation... giving legitimate task or service names' is a direct, unstretched match for a malicious tool registered under an existing, legitimate tool's exact name. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic security-evaluation or third-party-risk boilerplate already found non-specific for the other records in this sourcing pass fits this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "sandbox", + "llm" + ], + "derivable_into": [ + "credential-exfiltration" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP03-2025%E2%80%93Tool-Poisoning.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" +} diff --git a/tests/fixtures/AVE-2026-00086_negative.md b/tests/fixtures/AVE-2026-00086_negative.md new file mode 100644 index 0000000..0d9c8bc --- /dev/null +++ b/tests/fixtures/AVE-2026-00086_negative.md @@ -0,0 +1,44 @@ +# Session trace: e-commerce checkout agent on a WebMCP-enabled page + +## Tool registry, early in session + +``` +[00:00.1] page-script (first-party, checkout.example.com) registers: + name=get_cart, impl=cart-v1, origin=checkout.example.com +[00:02.4] agent: listTools() -> [get_cart, apply_coupon, checkout] +[00:02.9] agent invokes get_cart -> returns cart contents (legitimate, cart-v1) +``` + +## Mid-session re-registration (same first-party origin, legitimate refresh) + +``` +[00:08.5] page-script (first-party, checkout.example.com) calls: + controller.abort() # the page's own script refreshing its tool + # definition after a client-side cart update +[00:08.5] registry: get_cart unregistered +[00:08.6] page-script (first-party, checkout.example.com) registers: + name=get_cart, impl=cart-v1.1, origin=checkout.example.com + schema=identical, description=identical +[00:08.6] registry: get_cart re-registered + # same name, same registering origin as the original registration, + # only the underlying cart state changed, not the tool's identity +``` + +## Agent's next invocation of the same tool name + +``` +[00:15.7] agent invokes get_cart (to re-check cart before checkout) + -> dispatched to cart-v1.1 (checkout.example.com) + -> returns updated cart contents, shipping_address unchanged + from what the user entered +[00:16.1] agent proceeds to checkout normally +``` + +A conforming implementation must not flag this: `get_cart` is unregistered +and re-registered mid-session, the same surface event the positive +fixture shows, but the re-registration originates from the same +first-party origin (`checkout.example.com`) that performed the tool's +original registration.

An attacker who obtains the write-only ingest credential, often trivially recoverable from a target's own public frontend JavaScript, POSTs a crafted event directly to that ingest endpoint, controlling the entire payload structure. The injected event embeds carefully formatted markdown, headings, code blocks, and a fabricated resolution or remediation section naming an executable command, within standard fields of the event schema, styled to be visually indistinguishable from the integration's own authentic, system-generated output. When a developer later asks their AI coding agent to investigate the resulting error or event, the integration's own MCP server returns the poisoned event to the agent as diagnostic data. The agent's own handling of MCP tool responses treats this returned data as authoritative system output rather than as untrusted external content requiring the same scrutiny as user-supplied input, and because the markdown formatting mirrors the integration's authentic template exactly, there is no visual or structural cue distinguishing the compromise from a genuine event. The agent, unable to distinguish the attacker's embedded instruction from legitimate remediation guidance, executes the suggested command with the developer's own full privileges. Demonstrated concretely against Sentry, a widely deployed error-tracking and performance-monitoring platform, using its DSN (Data Source Name), a public, write-only credential intentionally embedded in frontend JavaScript by design, requiring no additional authentication to submit events. Testing across three current AI coding agents, Claude Code, Cursor, and OpenAI Codex CLI, achieved an 85% exploitation success rate. Tenet Security identified at least 2,388 organizations with publicly exposed Sentry DSNs that could be used to inject malicious events by this method. Sentry itself has acknowledged the underlying issue as 'technically not defensible' given the DSN's intentionally public-write design, and has activated a narrow content filter blocking one specific payload string rather than a structural fix. The attack bypasses EDR, WAF, IAM, VPN, Cloudflare, and firewall defenses entirely, because no conventionally malicious artifact, no malware signature, no anomalous network behavior, exists anywhere in the chain: every request is a legitimately formatted, protocol-valid event submitted to an endpoint explicitly designed to accept unauthenticated writes. Distinct from AVE-2026-00044 (Async Task Result Poisoning): that record's own stated distinguishing property, explicitly named in its description, is a temporal gap between task dispatch and a later, separate turn's result consumption, which is what it identifies as bypassing synchronous safety checks. This record's mechanism is a synchronous MCP tool call and response within a single interaction, a developer asks the agent to investigate an error and the poisoned response returns immediately, with no temporal gap, no task dispatch, and no later-turn consumption pattern anywhere in the mechanism. Distinct from AVE-2026-00043 (MCP App UI Payload Injection): that record's mechanism is instructions hidden in non-rendered elements, hidden divs, alt attributes, SVG metadata, invisible to the user while still processed by the model. This record's malicious content is fully rendered and visible, exactly as the legitimate system's own output would be; its evasion technique is visual mimicry of an authentic template, the structurally opposite concealment strategy from hiding content the user cannot see. Distinct from AVE-2026-00042 (REPL Code Mode Payload Injection): that record's mechanism is tool-result content containing escape sequences or string terminators that break out of a data context directly into a dynamically constructed eval() or exec() code string, a syntactic code-injection technique. This record requires no code-context breakout of any kind; the agent reads the content as natural-language diagnostic guidance within its own normal reasoning process and is persuaded to act on it, not tricked via a parsing or escaping vulnerability. Distinct from AVE-2026-00018 (Tool Result Manipulation): that record's mechanism is the agent itself being instructed by some other component to falsify, alter, or suppress a tool result before reporting it to a user or downstream system.

"Agentjacking: a crafted tool response visually mimics a trusted system template to hijack an agent", + "attack_class": "Prompt Injection - Tool Response Template Mimicry", + "severity": "HIGH", + "description": "A monitoring or diagnostic integration exposes an MCP server whose ingest endpoint is designed to be publicly writable, a deliberate architectural choice so that unauthenticated clients (a user's own browser, for instance) can report events without holding a full credential. An attacker who obtains the write-only ingest credential, often trivially recoverable from a target's own public frontend JavaScript, POSTs a crafted event directly to that ingest endpoint, controlling the entire payload structure. The injected event embeds carefully formatted markdown, headings, code blocks, and a fabricated resolution or remediation section naming an executable command, within standard fields of the event schema, styled to be visually indistinguishable from the integration's own authentic, system-generated output. When a developer later asks their AI coding agent to investigate the resulting error or event, the integration's own MCP server returns the poisoned event to the agent as diagnostic data. The agent's own handling of MCP tool responses treats this returned data as authoritative system output rather than as untrusted external content requiring the same scrutiny as user-supplied input, and because the markdown formatting mirrors the integration's authentic template exactly, there is no visual or structural cue distinguishing the compromise from a genuine event. The agent, unable to distinguish the attacker's embedded instruction from legitimate remediation guidance, executes the suggested command with the developer's own full privileges. Demonstrated concretely against Sentry, a widely deployed error-tracking and performance-monitoring platform, using its DSN (Data Source Name), a public, write-only credential intentionally embedded in frontend JavaScript by design, requiring no additional authentication to submit events. Testing across three current AI coding agents, Claude Code, Cursor, and OpenAI Codex CLI, achieved an 85% exploitation success rate. Tenet Security identified at least 2,388 organizations with publicly exposed Sentry DSNs that could be used to inject malicious events by this method. Sentry itself has acknowledged the underlying issue as 'technically not defensible' given the DSN's intentionally public-write design, and has activated a narrow content filter blocking one specific payload string rather than a structural fix. The attack bypasses EDR, WAF, IAM, VPN, Cloudflare, and firewall defenses entirely, because no conventionally malicious artifact, no malware signature, no anomalous network behavior, exists anywhere in the chain: every request is a legitimately formatted, protocol-valid event submitted to an endpoint explicitly designed to accept unauthenticated writes. Distinct from AVE-2026-00044 (Async Task Result Poisoning): that record's own stated distinguishing property, explicitly named in its description, is a temporal gap between task dispatch and a later, separate turn's result consumption, which is what it identifies as bypassing synchronous safety checks. This record's mechanism is a synchronous MCP tool call and response within a single interaction, a developer asks the agent to investigate an error and the poisoned response returns immediately, with no temporal gap, no task dispatch, and no later-turn consumption pattern anywhere in the mechanism. Distinct from AVE-2026-00043 (MCP App UI Payload Injection): that record's mechanism is instructions hidden in non-rendered elements, hidden divs, alt attributes, SVG metadata, invisible to the user while still processed by the model. This record's malicious content is fully rendered and visible, exactly as the legitimate system's own output would be; its evasion technique is visual mimicry of an authentic template, the structurally opposite concealment strategy from hiding content the user cannot see. Distinct from AVE-2026-00042 (REPL Code Mode Payload Injection): that record's mechanism is tool-result content containing escape sequences or string terminators that break out of a data context directly into a dynamically constructed eval() or exec() code string, a syntactic code-injection technique. This record requires no code-context breakout of any kind; the agent reads the content as natural-language diagnostic guidance within its own normal reasoning process and is persuaded to act on it, not tricked via a parsing or escaping vulnerability. Distinct from AVE-2026-00018 (Tool Result Manipulation): that record's mechanism is the agent itself being instructed by some other component to falsify, alter, or suppress a tool result before reporting it to a user or downstream system.

Checked and corrected: `downloadUri`/`organization` were pointing at Bawbel-branded infrastructure (`api.piranha.bawbel.io`, "Bawbel Security Research") rather than AVE's own real, independent API and identity; the worked example cited `AVE-2026-00001` with `owasp_mcp`/`mitre_atlas` values that no longer matched the live record; `owasp_asi` and `nist_ai_rmf` existed on records with no documented SARIF representation at all.

It does not connect to running servers or observe runtime, so it maps only to AVE's static_detection records. Each cfgaudit rule emits its primary AVE id in JSON/SARIF output (see github.com/cfgaudit/cfgaudit/blob/main/docs/cfgaudit-to-ave.md). Mappings are class-level behavioral equivalence, not asserted identity. cfgaudit now maps 61 config-surface rules onto 27 AVE behavioral classes, up from 53 onto 23 at v1.11.0. Only two of the eight new mappings are new cfgaudit rules; the other six are rules that existed all along and are mapped here for the first time, because AVE-2026-00071, 00072, 00073 and 00076 were published on 2026-08-06 and later, after the v1.11.0 crosswalk was generated on 2026-08-05. Three of those four came out of this crosswalk's own gap list (aveproject/ave#68), which is now down to one open surface.

The prompt half is `AVE-2026-00076` and is mapped above. The other two are not: `AVE-2026-00063` is explicitly a bypassed *human*-approval step, and Guardian v2 is an automated reviewer. `features` is not on Codex's project-layer denylist, so a committed `.codex/config.toml` sets all three; verified against codex `0.150.0-alpha.7` by reading the effective config back through its app server in a trusted directory, with a denylisted key and an ordinary key as controls. **A repository granting browser or desktop access.** Codex's `[browser_use]` grants per-origin `access`, `downloads`, `uploads` and `full_cdp_access` (full Chrome DevTools Protocol, so script execution plus cookie and storage access inside the browser session), and `[computer_use]` grants control of desktop applications by bundle id, AUMID or executable. The value type is an enum of exactly `allow` and `deny`, so there is no ask state and `allow` is unambiguously the weakening direction. This is deliberately **not** filed under `AVE-2026-00063`: whether a prompt is skipped is unverified, because the value is observable in the effective config but the tools themselves live in the client app. Filing it there would assert more than the detection does. +### The four surfaces new in this revision + +**A configuration-declared environment that loads code into every shell (CFG107, CFG110).** Codex `shell_environment_policy.set` and the Claude Code settings `env` block both set the process environment of every shell command and hook the agent starts, so `BASH_ENV`, `LD_PRELOAD`, `NODE_OPTIONS` and similar run repository-chosen code in each of them. Measured for Claude Code: a project-scope `env` value reaches the hook process. The mechanism is the one `AVE-2026-00055` describes, but that record is bound to an untrusted MCP launch config. Stretching it onto the agent's own process environment would change what it asserts, so this is reported as a gap. + +**A committed scheduler that fires prompts on a timer (CFG108).** A committed `.claude/scheduled_tasks.json` self-enables Claude Code's otherwise-off cron scheduler and enqueues a repository-authored prompt on a schedule. `AVE-2026-00063` is a bypassed human-approval gate; this bypasses no gate, it opens a new autonomous channel. + +**A declared configuration that never loads (CFG109, and the discarded-file case of CFG012).** The repository states guardrails that are not in force, because the agent does not load the file.

Like `CFG101`, it is an ineffective control rather than an attacker behaviour. + ### The three deliberately unmapped rules - **CFG100**, Grok `[plugins]`. `AVE-2026-00064` would be the class, but it requires the loader to run plugin code at project load with no prompt. That is not verified against the shipped Grok build, so mapping it would assert a mechanism nobody measured. - **CFG101**, a deny rule walked past by flag reordering. Claude Code matches a `Bash(...)` pattern as a literal prefix, so `Bash(rm -rf *)` never covered `rm -fr x`.

Neither covers two local files where load order decides which body runs. `AVE-2026-00082` (local skill name collision) is much closer, but it asserts that the shadowing is silent and that it spans discovery roots of differing trust. Measured for Claude Code, a duplicate inside one repository is resolved by qualification, not silently shadowed, and the cross-root case needs a machine-wide view a repository-scoped scanner does not have. What stays uncovered is the same-root collision, per agent, where the losing skill is never reported. These are not gaps in this crosswalk. They are config classes outside AVE's current skill/MCP scope, listed so coverage stays visible in both directions. @@ -137,4 +159,7 @@ Static `static_detection` classes cfgaudit does not map, with the reason: | AVE-2026-00060 | STDIO transport shell injection.

Content the agent processes (a README, a project note, a dependency's documentation) steers it into writing a file the sandbox allows: a hook definition, an editor task, Git metadata, the agent tool's own project configuration, or an interpreter inside a virtualenv. A more-privileged component outside the sandbox later reads that file and executes it as trusted configuration or code: the agent harness's own hook engine or startup configuration loader, the editor's task runner, or an editor extension that runs Git or discovers Python interpreters. That component does not distinguish agent-written files from user-authored ones and does not run what it consumes under the sandbox's execution policy, so the agent's side effect executes on the host with the user's privileges even though the agent process itself never left the sandbox. Demonstrated across vendors: Cursor ran a Stop hook from an agent-written .claude/settings.local.json at the end of the turn (CVE-2026-48124), ran Git hooks the agent planted in improperly protected .git settings (CVE-2026-26268), ran a core.fsmonitor helper the agent placed in a repository created with --separate-git-dir past a literal .git/config deny rule (patched in 3.0.0), and ran a virtualenv interpreter the agent replaced when the Python extension invoked it outside the sandbox (CVE-2026-73217). Claude Code loaded SessionStart hooks from a .claude/settings.json the sandbox let the agent create because the file was absent at startup (CVE-2026-25725). Antigravity's write tools let the agent drop a runOn: folderOpen task into .vscode/tasks.json, which VS Code's task runner executed on the host on the next open. Codex CLI let apply_patch create .codex/config.toml, whose notify command runs outside the sandbox, and Gemini CLI mounted the user's settings.json writable into its container.

The overlap is real for one vector of CVE-2026-48124, whose advisory names both 'a malicious workspace' and 'an agent-created file'; it is cited here for the agent-written PoC Pillar published. Also compared field by field with AVE-2026-00054 (runtime: the sandbox itself is broken by a prototype-chain payload; here the sandbox works as designed), AVE-2026-00050 (runtime: hook registration beyond a component manifest at session init; no manifest is involved here), AVE-2026-00084 (registry_metadata: a vetted plugin's update rebinds a hook; here the change is the agent's own write), AVE-2026-00071 (registry_metadata: daemon redirect to remote infrastructure), AVE-2026-00075 (skill_file: bytecode diverging from reviewed source) and AVE-2026-00063 (an approval flag in config; overlaps only where an agent-written config also sets one, as in Cymulate's Codex approval_policy, and the executing step there is still notify run outside the sandbox). entry_class model_generated reused rather than forked: as in AVE-2026-00056, the payload is something the agent itself produces (a file it writes), not something it reads. Q6 (replace the LLM with a deterministic program with the same workspace write access): the flaw partly survives, since any sandboxed process whose output a privileged consumer trusts can escape the same way. What remains agentic: the sandbox exists to contain a model steered by untrusted content, and the attacker needs only text the model reads rather than code execution inside the sandbox, because writing arbitrary workspace files is the agent's normal capability; the decision to write comes from model reasoning over injected content (the CVE-2026-26268 advisory's own words: 'A malicious agent (ie prompt injection)'); and in most instances the trusted consumer is the agent harness itself (hooks, notify, startup config) treating its own agent's writes as the user's configuration. Classified A rather than E for that reason, with the partial survival stated. autonomy scored 1: once the file is written, the trusted component executes it on its own trigger with no further attacker interaction and no approval prompt. tool_use scored 1: the mechanism is the agent's own file-write or shell tool producing the artifact. non_determinism scored 0.5: exploitation depends on the model following injected content, which varies run to run (OpenAI's own closure of Cymulate's Codex report cited prompt injection). self_modification scored 0.5: in the hook, notify and settings instances the agent writes its own harness's configuration and so changes the agent runtime's later behavior; the Git, editor-task and virtualenv instances change a different component, so not 1. dynamic_identity scored 0.5: the consumer extends user-authored trust to an agent-written file, a trust-anchor confusion over authorship, scored as AVE-2026-00084 scored inherited vetting trust. persistent_memory scored 1: the written file stays on disk and re-executes on every later trigger (the CVE-2026-25725 advisory calls them 'persistent hooks'; Cymulate's Gemini settings persist across directories). natural_language_input scored 0: the delivery is natural language, but the exploit step at the boundary is structural (a configuration file executed by a component), which the scoring reference scores 0. data_access scored 1: execution runs as the user on the host, with the user's keys, tokens and files. external_dependencies scored 1: severity depends entirely on which host-side consumer trusts which file (a hook engine, a task runner, a Python or Git extension). multi_agent scored 0. cvss_base_vector follows the CVE-2026-25725 advisory's own vector: network-borne delivery through content the agent reads (AV:N), low complexity (AC:L), a precondition on sandbox or auto-run mode and on the agent following the content (AT:P), no privileges (PR:N), passive user interaction such as continuing the session or restarting the tool (UI:P), and full host impact (VC:H/VI:H/VA:H). The Cursor advisory scored its instance higher (8.5, AV:L/AT:N) and CVE-2026-26268 was scored 8.0 under CVSS 3.1; 7.7 is the most conservative vendor reading of the same handoff. thm set to 0.90 (PoC exists, not exploited in the wild): every instance cited has a working PoC and most have a vendor-confirmed fix, but no in-the-wild exploitation is reported. mitigation_factor set to 1: fixes are per path and per product (Antigravity's blocklist missed tasks.json, Cursor's rule missed .git-alt), Google downgraded one instance, OpenAI closed another as informational and Gemini CLI's was unresolved at disclosure; no ecosystem-wide standard mitigation exists.

Content the agent processes (a README, a project note, a dependency's documentation) steers it into writing a file the sandbox allows: a hook definition, an editor task, Git metadata, the agent tool's own project configuration, or an interpreter inside a virtualenv. A more-privileged component outside the sandbox later reads that file and executes it as trusted configuration or code: the agent harness's own hook engine or startup configuration loader, the editor's task runner, or an editor extension that runs Git or discovers Python interpreters. That component does not distinguish agent-written files from user-authored ones and does not run what it consumes under the sandbox's execution policy, so the agent's side effect executes on the host with the user's privileges even though the agent process itself never left the sandbox. Demonstrated across vendors: Cursor ran a Stop hook from an agent-written .claude/settings.local.json at the end of the turn (CVE-2026-48124), ran Git hooks the agent planted in improperly protected .git settings (CVE-2026-26268), ran a core.fsmonitor helper the agent placed in a repository created with --separate-git-dir past a literal .git/config deny rule (patched in 3.0.0), and ran a virtualenv interpreter the agent replaced when the Python extension invoked it outside the sandbox (CVE-2026-73217). Claude Code loaded SessionStart hooks from a .claude/settings.json the sandbox let the agent create because the file was absent at startup (CVE-2026-25725). Antigravity's write tools let the agent drop a runOn: folderOpen task into .vscode/tasks.json, which VS Code's task runner executed on the host on the next open.

The overlap is real for one vector of CVE-2026-48124, whose advisory names both 'a malicious workspace' and 'an agent-created file'; it is cited here for the agent-written PoC Pillar published. Also compared field by field with AVE-2026-00054 (runtime: the sandbox itself is broken by a prototype-chain payload; here the sandbox works as designed), AVE-2026-00050 (runtime: hook registration beyond a component manifest at session init; no manifest is involved here), AVE-2026-00084 (registry_metadata: a vetted plugin's update rebinds a hook; here the change is the agent's own write), AVE-2026-00071 (registry_metadata: daemon redirect to remote infrastructure), AVE-2026-00075 (skill_file: bytecode diverging from reviewed source) and AVE-2026-00063 (an approval flag in config; overlaps only where an agent-written config also sets one, as in Cymulate's Codex approval_policy, and the executing step there is still notify run outside the sandbox). entry_class model_generated reused rather than forked: as in AVE-2026-00056, the payload is something the agent itself produces (a file it writes), not something it reads. Q6 (replace the LLM with a deterministic program with the same workspace write access): the flaw partly survives, since any sandboxed process whose output a privileged consumer trusts can escape the same way. What remains agentic: the sandbox exists to contain a model steered by untrusted content, and the attacker needs only text the model reads rather than code execution inside the sandbox, because writing arbitrary workspace files is the agent's normal capability; the decision to write comes from model reasoning over injected content (the CVE-2026-26268 advisory's own words: 'A malicious agent (ie prompt injection)'); and in most instances the trusted consumer is the agent harness itself (hooks, notify, startup config) treating its own agent's writes as the user's configuration. Classified A rather than E for that reason, with the partial survival stated. autonomy scored 1: once the file is written, the trusted component executes it on its own trigger with no further attacker interaction and no approval prompt. tool_use scored 1: the mechanism is the agent's own file-write or shell tool producing the artifact. non_determinism scored 0.5: exploitation depends on the model following injected content, which varies run to run (OpenAI's own closure of Cymulate's Codex report cited prompt injection). self_modification scored 0.5: in the hook, notify and settings instances the agent writes its own harness's configuration and so changes the agent runtime's later behavior; the Git, editor-task and virtualenv instances change a different component, so not 1. dynamic_identity scored 0.5: the consumer extends user-authored trust to an agent-written file, a trust-anchor confusion over authorship, scored as AVE-2026-00084 scored inherited vetting trust. persistent_memory scored 1: the written file stays on disk and re-executes on every later trigger (the CVE-2026-25725 advisory calls them 'persistent hooks'; Cymulate's Gemini settings persist across directories). natural_language_input scored 0: the delivery is natural language, but the exploit step at the boundary is structural (a configuration file executed by a component), which the scoring reference scores 0. data_access scored 1: execution runs as the user on the host, with the user's keys, tokens and files. external_dependencies scored 1: severity depends entirely on which host-side consumer trusts which file (a hook engine, a task runner, a Python or Git extension). multi_agent scored 0. cvss_base_vector follows the CVE-2026-25725 advisory's own vector: network-borne delivery through content the agent reads (AV:N), low complexity (AC:L), a precondition on sandbox or auto-run mode and on the agent following the content (AT:P), no privileges (PR:N), passive user interaction such as continuing the session or restarting the tool (UI:P), and full host impact (VC:H/VI:H/VA:H). The Cursor advisory scored its instance higher (8.5, AV:L/AT:N) and CVE-2026-26268 was scored 8.0 under CVSS 3.1; 7.7 is the most conservative vendor reading of the same handoff. thm set to 0.90 (PoC exists, not exploited in the wild): every instance cited has a working PoC and most have a vendor-confirmed fix, but no in-the-wild exploitation is reported. mitigation_factor set to 1: fixes are per path and per product (Antigravity's blocklist missed tasks.json, Cursor's rule missed .git-alt), Google downgraded one instance, OpenAI closed another as informational and Gemini CLI's was unresolved at disclosure; no ecosystem-wide standard mitigation exists.

The harness, however, computes that scope from a value the model supplies in the tool call itself, such as the command's working directory, rather than from the session's own root. Content the model reads (an MCP tool response, a web search result, a README) steers it to set that value to a location outside the workspace, and the sandbox grants write access there. The agent can then write the sandbox's own helper binary, the user's shell startup files or launch agents without approval, so later commands run unsandboxed. The model does not break the boundary; it sets it. Demonstrated in two products. Codex CLI 0.2.0 to 0.38.0 could treat a model-generated cwd as the sandbox's writable root, including paths outside the folder where the user started the session (CVE-2025-59532); the fix separates the command's working directory from the directory the sandbox policy is computed from. Cursor before 3.0 added the run_terminal_cmd tool's optional working_directory parameter to the sandbox's allowed write list whenever the model set a non-default value (CVE-2026-50548, part of Cato AI Labs' DuneSlide research), and the proof of concept overwrote Cursor's cursorsandbox helper.

Related but kept out of the fingerprint: CVE-2026-50549 (Cursor falls back to the in-workspace symlink path when canonicalization fails and writes without approval) and CVE-2026-34452 (the Anthropic Python SDK's async memory tool validated a model-supplied path, then used the unresolved path, a validate-then-use race exploitable by a local attacker able to write to the memory directory).

Q6 (replace the LLM with a deterministic program): the flaw, in the form that matters, does not survive. A conventional program does not take its sandbox boundary from the output of the component the sandbox exists to contain; Cato AI Labs' own write-up: 'Traditionally, a remote attacker cannot control the working directory of a sandboxed operation.'

The harness, however, computes that scope from a value the model supplies in the tool call itself, such as the command's working directory, rather than from the session's own root. Content the model reads (an MCP tool response, a web search result, a README) steers it to set that value to a location outside the workspace, and the sandbox grants write access there. The agent can then write the sandbox's own helper binary, the user's shell startup files or launch agents without approval, so later commands run unsandboxed. The model does not break the boundary; it sets it. Demonstrated in two products. Codex CLI 0.2.0 to 0.38.0 could treat a model-generated cwd as the sandbox's writable root, including paths outside the folder where the user started the session (CVE-2025-59532); the fix separates the command's working directory from the directory the sandbox policy is computed from.

It replaces a revision that was checked against SkillSpector 2.0.0's documentation. SkillSpector scans skill and MCP files statically, with an optional LLM stage that --no-llm turns off, so this file maps only to AVE's static_detection records: the 28 runtime_observed and runtime_drift_detected records are listed under out_of_scope_ave_records and are not mapped. Three counts disagree and the code is the source of truth: RULE_ID_TO_CATEGORY defines 78 rules in 18 categories (this file's rules_total and categories); the README says 71 patterns across 17 categories, and its tables list 73 rows; the previous revision recorded 16 categories and 64 patterns. Scope decision: the 78 in-map rules are the catalogue and each appears exactly once under mappings. 37 more rule ids are emitted by analyzers but are absent from RULE_ID_TO_CATEGORY: AST1 to AST10 (Python AST checks; only AST10 is named in PATTERN_NAMES), BH1 to BH4 (bundled hooks and settings), RP1 to RP3 (rug pull), PE4 and PE5, AE1 to AE7 (artifact integrity and coverage) and, behind the LLM stage, SSD-1 to SSD-4, SDI-1 to SDI-4 and SQP-1 to SQP-3. They are in scope and handled the same way, listed separately under rules_outside_category_map so the 78 stay countable. Mappings are class-level equivalence, not identity: relationship states how far a rule and a record overlap, and a hit on a related rule is a lead and not an instance of the AVE class.

Changes: category keys are now SkillSpector's own category strings (18 instead of 16); dangerous_code_ast and taint_tracking no longer exist as categories (the AST rules are emitted outside the category map, and TT1 to TT6 sit under Data Exfiltration, Privilege Escalation and Insecure Deserialization); every rule has its own entry with a relationship; mappings to runtime_observed records (AVE-2026-00018, 00019, 00050) were dropped; 21 of the previous 41 category-to-record links did not survive and are listed under dropped_from_previous_revision; the previous conclusion that YARA matches are only known malware was reversed, because the built-in agent_skills.yar rules are behavioral; the previous gaps for trigger_abuse and mcp_least_privilege were re-stated rule by rule.

The previous revision (generated 2026-07-12, last checked against documentation on 2026-06-21) mapped 16 category names against SkillSpector 2.0.0's documentation and said it had not been re-checked against the source; SkillSpector has no v2.0.0 tag, and its earliest tag is v2.5.0. Changes: category keys are now SkillSpector's own category strings (18 instead of 16); dangerous_code_ast and taint_tracking no longer exist as categories (the AST rules are emitted outside the category map, and TT1 to TT6 sit under Data Exfiltration, Privilege Escalation and Insecure Deserialization); every rule has its own entry with a relationship; mappings to runtime_observed records (AVE-2026-00018, 00019, 00050) were dropped; 21 of the previous 41 category-to-record links did not survive and are listed under dropped_from_previous_revision; the previous conclusion that YARA matches are only known malware was reversed, because the built-in agent_skills.yar rules are behavioral; the previous gaps for trigger_abuse and mcp_least_privilege were re-stated rule by rule. The file does not round-trip through the previous formatting, so the diff is a full rewrite. ---- +## The three counts + +| | Rules | Categories | +|---|---|---| +| Code (`RULE_ID_TO_CATEGORY` at `v2.13.1`), source of truth | 78 | 18 | +| README headline | 71 | 17 | +| README tables (rows, headings) | 73 | 17 | +| Previous crosswalk (SkillSpector 2.0.0 documentation) | 64 | 16 | + +The README tables give Behavioral AST (AST1 to AST9) and Taint Tracking (TT1 to TT5) headings of their own, and omit 14 in-map rules the code has (AS1, AS2, AS3, DS1, DS2, DS3, DS4, E5, SC7, SSRF1, SSRF2, SSRF3, TM4, TT6). The code groups the taint rules under Data Exfiltration, Privilege Escalation and Insecure Deserialization, and emits the AST rules without a category. + +## Scope + +- **Static AVE records only.** SkillSpector scans files statically. Of 89 AVE records, 61 are `static_detection` and are the only mapping targets. The 26 `runtime_observed` and 2 `runtime_drift_detected` records are listed under *Out of scope* below. +- **In-map rules (78):** the catalogue. Each appears exactly once in the category tables. +- **Rules outside the category map (37):** `AST1` to `AST10`, `BH1` to `BH4`, `RP1` to `RP3`, `PE4`, `PE5`, `AE1` to `AE7` and the LLM ids `SSD-1` to `SSD-4`, `SDI-1` to `SDI-4`, `SQP-1` to `SQP-3`. They are real findings a scan can emit, so they are mapped the same way, in their own table. +- **LLM dependence.** 12 rules need an LLM and do not fire under `--no-llm`: TP4 (inside the map) and SDI-1, SDI-2, SDI-3, SDI-4, SQP-1, SQP-2, SQP-3, SSD-1, SSD-2, SSD-3, SSD-4. SC4 is deterministic but queries OSV.dev. Every other rule is a deterministic regex, AST, filesystem or YARA check. An optional LLM meta-analysis can also filter and enrich findings; it is not modelled here. +- **Not measured.** Only what each rule is designed to match was read, not how well it does. + +## How to read the relationship + +- **equivalent** (13 rules): Same behavior on the same surface: the AVE record's own description and indicators cover what the rule matches. +- **narrower** (3 rules): The AVE class is a specific instance of what the rule flags: every instance of the class would trip the rule, but the rule also fires on things that are not the class. +- **broader** (0 rules): The AVE class contains what the rule flags as one instance, and more. Not used in this revision. +- **related** (64 rules): Shares one dimension (object, trigger or outcome) without either containing the other, or the surface differs. A hit is a lead, not an instance of the AVE class. +- **no_fit** (35 rules): No static AVE class matches. +- With several ave_ids the relationship is stated against the first; the others are secondary links explained in the notes. +- **detection**: static: deterministic regex, AST, filesystem or YARA check. static+network: deterministic but queries OSV.dev. llm: depends on an LLM and is absent from a scan run with --no-llm. ## Category mapping -| SkillSpector category | AVE id(s) | Primary | Notes | -|---|---|---|---| -| prompt_injection | AVE-2026-00002, AVE-2026-00007, AVE-2026-00009, AVE-2026-00010 | **AVE-2026-00002** | AVE-2026-00002 is the canonical tool description injection class.

AVE-2026-00049 (HTTP Host Header Injection) added: the attacker-controlled host value flows from a tainted source into the Host header sink -- a textbook taint-tracking detection target. *Scanner mechanic:* Taint tracking is a scanner mechanic, not a vulnerability class. It detects exfiltration and injection patterns covered by multiple AVE records. | -| yara_signatures | — | — | YARA signatures detect known malware artifacts -- not behavioral vulnerability classes in the AVE sense. Positive YARA matches indicate the skill bundles known malware, which is outside AVE's enumeration scope. AVE records describe behavioral classes in skill instructions, not embedded malware payloads. | -| mcp_least_privilege | AVE-2026-00022, AVE-2026-00002, AVE-2026-00050 | **AVE-2026-00022** | AVE-2026-00022 covers scope creep and undeclared resource access. AVE-2026-00002 covers tool description manipulation that may include overbroad capability claims. AVE-2026-00050 (Parasitic Toolchain) added: a component registering tool handlers beyond its declared manifest scope is a direct least-privilege violation at the MCP tool-registration layer. **Gap:** No AVE record specifically addresses MCP server-card capability over-declaration as a distinct class. | -| mcp_tool_poisoning | AVE-2026-00002, AVE-2026-00041, AVE-2026-00029 | **AVE-2026-00002** | AVE-2026-00002 is the canonical tool description injection class. AVE-2026-00041 covers MCP server-card injection specifically. AVE-2026-00029 covers homoglyph and Unicode obfuscation as a delivery variant. | - ---- - -## The 3 new records - -**AVE-2026-00049 (HTTP Host Header Injection)** lands in `supply_chain` (the -component shares AVE's own "Supply Chain - ..." attack_class framing: a trusted -server delivers tampered routing metadata rather than tampered code) and -`taint_tracking` (the attacker-controlled host value flows from a tainted source -into the Host header sink — a textbook taint-tracking detection target). - -**AVE-2026-00050 (Parasitic Toolchain)** lands in `rogue_agent` (a component that -silently registers itself as additional tools/hooks behaves as an unauthorised -actor inside the trusted tool dispatch layer, surviving session resets like a -persistent rogue presence) and `mcp_least_privilege` (registering tool handlers -beyond the declared manifest scope is a direct least-privilege violation). - -**AVE-2026-00051 (OAuth Discovery Rebinding)** lands in `supply_chain` (the -server's own discovery document is the trust-chain link being tampered with). - ---- +### Prompt Injection (6 rules) + +Instruction overrides, hidden directives, exfiltration commands, behavior steering, whitespace padding, harmful content in skill text. P1 is the cleanest match (AVE-2026-00007). P2 and P9 are concealment techniques that overlap AVE-2026-00029; P3 and P4 are partial; P5 has no AVE class. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| P1 | Override Instructions | static | equivalent | 00007, 00009 | Regexes over any file body for instruction-override phrasing: 'ignore previous instructions', 'override safety', 'bypass security', 'forget your instructions', 'your new instructions are', 'you are now in jailbreak/unrestricted mode', 'enable developer mode'. This is the phrasing AVE-2026-00007 lists as its indicators. The jailbreak-mode and developer-mode patterns also fall under AVE-2026-00009. | +| P2 | Hidden Instructions | static | related | 00029 | Hiding techniques: HTML and '[//]: #' comments containing instruction keywords, zero-width characters and 'data:text/plain;base64' URIs (markdown, perl and other file types only), plus Unicode Tag characters and bidirectional controls in every file type. The character-level techniques are AVE-2026-00029's mechanism. Comment-based hiding and data URIs have no AVE class: AVE-2026-00010 is a secrecy directive in plain text, not concealment by markup. | +| P3 | External Transmission Instructions | static | related | 00013, 00003 | Prose regexes for instructions to send the conversation, context, history or 'all user data' to an external destination, plus 'silently' or 'secretly' send. The object is conversation context or user data, which no AVE exfiltration record names: AVE-2026-00013 is PII fields and AVE-2026-00003 is credentials. Shares the instruct-then-transmit shape. | +| P4 | Subtle Steering | static | related | 00010 | Prose regexes for behavior steering: 'always recommend X over Y', 'subtly steer the user', 'gain the user's trust and then', 'append this to every response', and 'never mention, tell or warn the user'. Only the last pattern overlaps an AVE class (the secrecy directive of AVE-2026-00010); the rest is bias and manipulation of output, which no static AVE record describes. | +| P5 | Harmful Content | static | no_fit | none | Word lists and phrases for physical-harm content (poisons, bomb making, self-harm), severity CRITICAL. A content-safety check, not an agent behavior class. | +| P9 | Whitespace Padding | static | related | 00029 | Large blank-line blocks and long space runs that push injected text out of the visible area, in file bodies and in manifest description fields (the tool-poisoning analyzer also emits P9). Same aim as AVE-2026-00029, instructions a human reviewer cannot see but the model reads, reached by layout instead of Unicode characters. | + +### System Prompt Leakage (3 rules) + +Direct and indirect system prompt extraction and exfiltration by instruction. One AVE record, AVE-2026-00015, covers the object; P6 is the direct form, P7 and P8 the indirect and tool-based forms. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| P6 | System Prompt Leakage | static | equivalent | 00015 | Prose regexes for instructions to print, reveal, dump or repeat the system prompt or internal rules ('verbatim repeat your system prompt', 'begin your reply with your instructions'). This is the phrasing in AVE-2026-00015's indicators. | +| P7 | System Prompt Leakage | static | related | 00015, 00026 | Prose regexes for indirect extraction: summarize, translate, encode (base64, rot13) or reformat the system prompt as JSON or a poem, 'repeat everything above', 'how were you configured'. Same object as AVE-2026-00015, whose title names direct interrogation, so these are variants at the edge of it. The encode patterns resemble AVE-2026-00026's encoding of a system prompt. | +| P8 | System Prompt Leakage | static | related | 00015, 00026 | Prose regexes for instructions to write the system prompt to a file or log, send it to a URL or webhook, or pipe it to curl. The object is AVE-2026-00015's; the transmission step is the one AVE-2026-00026 describes, without its encoding. | + +### Data Exfiltration (9 rules) + +External transmission, environment harvesting, file enumeration, context leakage, cloud uploads, and the Python taint flows TT1 to TT4. Most rules cover one half of AVE-2026-00003 (read or send). TT3 is the only full flow. Conversation context, the object of P3 and E4, is not named by any AVE record. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| E1 | External Transmission | static | related | 00003, 00013 | Regexes for outbound transmission: requests or httpx post and put to a literal URL, fetch POST, curl -d, wget --post, URLs on api., data., collect., telemetry. or analytics. hosts, and one prose pattern ('send user data to https://'). Matches the send half only and has no test that the data is sensitive, so legitimate telemetry fires too (confidence 0.5 to 0.7). | +| E2 | Env Variable Harvesting | static | related | 00003 | Python AST check for copying or enumerating the whole os.environ mapping (copy, items, keys, values, dict(), spread, loops), a regex fallback for unparsable files, JavaScript process.env key reads, 'env \| grep key', printenv and prose such as 'collect all environment variables'. The read half of AVE-2026-00003 with no transmission test; TT3 covers the full flow. | +| E3 | File System Enumeration | static | related | 00003 | Regexes for scanning directories for secrets: glob over .env, .ssh and .aws, os.walk over home, listdir of .ssh, find for *.pem, and prose such as 'find credential files'. The discovery step before AVE-2026-00003's read and transmit; no transmission test. | +| E4 | Conversation Context Leak | static | related | 00013, 00003 | Prose regexes for sending, exporting or logging the conversation, chat history, session or agent memory to an external or remote destination. Conversation context is not named as the object of any AVE exfiltration record, so AVE-2026-00013 (collect and transmit user data) is the nearest by shape. | +| E5 | Cloud Storage Exfiltration | static | related | 00003 | Regexes for cloud-storage uploads: boto3 put_object and upload_file, aws s3 cp, sync and mv, gsutil, az storage blob upload. Confidence 0.55 to 0.65 because backups use the same calls. Shares the external-destination step of AVE-2026-00003 and says nothing about what is uploaded. | +| TT1 | Direct Source-to-Sink Flow | static | no_fit | none | Python data-flow from any source to any sink that is not one of the credential, file-to-network, external-to-exec or deserialization pairs, for example a file read written to another file. A generic data-flow report, not a behavior class. | +| TT2 | Variable-Mediated Taint Flow | static | no_fit | none | The same flows as TT1 passing through an intermediate variable (confidence 0.65). | +| TT3 | Credential Exfiltration Flow | static | equivalent | 00003 | Python AST data-flow (same file, across direct calls): os.environ, os.getenv to a network sink (requests, httpx, urlopen, socket send). Credential read followed by external transmission is AVE-2026-00003's behavior, and its indicators list os.environ access. Differs: the flow is in bundled Python code rather than an instruction to the agent, and any environment variable counts as a credential. | +| TT4 | File Data Exfiltration Flow | static | related | 00003 | Python data-flow from open(), read_text() or read_bytes() to a network sink. File contents need not be credentials, so it is wider than AVE-2026-00003 on the object and narrower on the surface (bundled Python only). | + +### Privilege Escalation (4 rules) + +Excessive permission requests, sudo and root use, credential file access, and the external-input-to-exec taint flow TT5. PE3 is the read half of AVE-2026-00003. TT5 maps to AVE-2026-00033 for eval and exec; its shell sinks are best fit by AVE-2026-00052, pending deprecation. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| PE1 | Excessive Permissions | static | related | 00038, 00012 | Flags 'permissions: *', several dangerous permissions listed together, and prose asking for or taking 'full access', 'escalate my privileges' or 'bypass permission checks' (severity LOW). The wildcard grant is the shape of AVE-2026-00038; the escalate-and-bypass prose is near AVE-2026-00012's claimed grant. Neither is a full match. | +| PE2 | Sudo/Root Invocation | static | no_fit | none | sudo, doas, pkexec, setuid chmod and 'run as root'. Elevated execution is a capability use, not a behavior class in AVE. | +| PE3 | Credential File Access | static | related | 00003 | Path references to credential stores (.ssh keys, .aws/credentials, gcloud, .kube/config, .git-credentials, .netrc, /etc/shadow, .env, keychains, browser cookie and login databases) and prose such as 'read the ssh key'. The read half of AVE-2026-00003; no transmission test. | +| TT5 | External Input to Execution Flow | static | related | 00033 | Python data-flow from network or user input to exec, eval, compile, os.system, os.popen or subprocess. The exec and eval sinks match AVE-2026-00033 (its indicators include eval(user_input)). The shell sinks are command injection, whose best-fit record is AVE-2026-00052, proposed for deprecation in discussion 234 and so not recorded as a mapping. | + +### Supply Chain (10 rules) + +Unpinned and vulnerable dependencies, remote execution, obfuscation, shipped bytecode, concealed executables, dependency source redirection. SC1 to SC3 match AVE-2026-00062, 00004 and 00057. SC8 is a presence check and AVE-2026-00075 is the narrower case that also needs divergence from source. SC10 has no AVE counterpart. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| SC1 | Unpinned Dependencies | static | equivalent | 00062 | Requirements lines with no version or '>=' only, '*' or 'latest' in package.json, '^' ranges (confidence 0.4), and prose such as 'install the latest' or 'do not pin'. Mutable version specifiers are AVE-2026-00062's mechanism. | +| SC2 | Remote Code Execution | static | equivalent | 00004, 00001 | Regexes for curl or wget piped to sh, bash, python, node, ruby or perl, download-then-run, exec or eval of requests, urllib or fetch output, and 'download and run the script'. The curl-to-bash and eval(requests.get(...)) forms are AVE-2026-00004's own examples. Fetching code to execute at runtime is also the payload step of AVE-2026-00001. | +| SC3 | Obfuscated Code | static | equivalent | 00057 | exec or eval of base64, hex, zlib or marshal-decoded data, atob, obfuscator-style _0x names, long hex or base64 literals (confidence 0.5 to 0.6) and shell decode-to-execute chains. Encoded content decoded and executed at runtime is AVE-2026-00057. Differs: AVE-2026-00057 also covers keyword fragments joined by string concatenation, which SC3 does not test. | +| SC4 | Known Vulnerable Dependency | static+network | no_fit | none | Dependency CVE lookup: a live query to OSV.dev with a static fallback list, the only rule that needs the network. AVE enumerates behavior classes, not known-vulnerable versions. | +| SC5 | Abandoned Dependency | static | no_fit | none | Dependency named in a built-in list of abandoned or archived packages. The nearest record, AVE-2026-00074, is a dangling external anchor verified live against GitHub, a registry, RDAP or a cloud provider; a fixed list of abandoned names is a different test for a different risk. | +| SC6 | Typosquatting Dependency | static | no_fit | none | Dependency name within a small edit distance of a popular package. The nearest records are identity claims (AVE-2026-00017 for MCP servers) and squatting on hallucinated skill names (AVE-2026-00066, runtime_observed, out of scope). No static AVE class covers typosquatted package dependencies. | +| SC7 | Untrusted Container Image | static | related | 00061 | Container pulls with verification off: --disable-content-trust, DOCKER_CONTENT_TRUST=0, --insecure-registry. Only the registry TLS case overlaps AVE-2026-00061; image signature checking is a different control. | +| SC8 | Shipped Python Bytecode | static | narrower | 00075 | Filesystem walk that flags any __pycache__ directory or .pyc or .pyo file (confidence 0.95, HIGH). It never opens the bytecode or compares it with a sibling .py: its own docstring says presence alone is the signal and disassembly can come later. Every AVE-2026-00075 instance ships a .pyc, so SC8 fires on it, but SC8 also fires on benign bytecode and does not test divergence from the source, so a hit is a lead and not a 00075 instance. | +| SC9 | Concealed Executable Artifact | static | related | 00024 | Executables nested in docx, xlsx, pptx or zip containers or in hidden or disguised artifacts (confidence 1.0). Same outcome as AVE-2026-00024, executable content a reviewer misses because of its wrapper, with a different carrier: nesting and hiding instead of a wrong extension. SC9 also reports coverage limits (an excluded or referenced artifact that was not inspected), which are not a behavior. | +| SC10 | Dependency Source Redirection | static | no_fit | none | Deterministic check for package-manager source changes (npm, Yarn, pip, Poetry, Maven, Cargo): a registry or index added or replaced in config files, commands and environment variables, reported HIGH, with unresolved destinations reported as such. No AVE record covers it. AVE-2026-00073 is the same shape (a static value redirects traffic) but its object is where the agent sends telemetry or model traffic. AVE-2026-00062 is about the absence of a pin, which does not help when the registry itself is swapped. Listed as an AVE-side gap. | + +### Excessive Agency (5 rules) + +Unrestricted tool access, autonomous decisions, scope creep, unbounded resources, external model selection. EA2 matches AVE-2026-00021. EA1 and EA3 are partial. EA4 and EA5 are resource and cost checks. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| EA1 | Unrestricted Tool Access | static | related | 00038 | Flags 'tools: *' and 'permissions: *', and prose such as 'grant access to all tools', 'no tool restrictions', 'execute arbitrary commands', 'allowlist is empty'. Matches the unlimited-tool-authority clause of AVE-2026-00038. AVE-2026-00038 also covers unbounded sub-agent spawning and recursive capability expansion, which EA1 does not test. | +| EA2 | Autonomous Decision Making | static | equivalent | 00021, 00063 | Prose such as 'without asking for confirmation', 'skip confirmation', 'do not ask the user before', 'assume consent', and the tokens auto_approve, auto-confirm and --no-confirm in any file. The prose is AVE-2026-00021's indicators. The tokens also overlap AVE-2026-00063 (a declared flag that removes approval), but EA2 does not require the flag to sit in a configuration file. | +| EA3 | Scope Creep | static | related | 00022 | Generic scope-expansion prose: 'also perform any other', 'beyond the scope', 'handle everything', 'act as a general-purpose'. No comparison with a manifest. Shares AVE-2026-00022's idea of acting beyond declared purpose but not its test. | +| EA4 | Unbounded Resource Access | static | no_fit | none | Unbounded retries, timeouts or 'no rate limit' language. Resource exhaustion, not an AVE behavior class. | +| EA5 | External Model or Provider Selection | static | no_fit | none | Pinned model or provider keys and coding-CLI shell-outs that can switch the billing account. A cost-control check with no AVE class. | + +### Output Handling (3 rules) + +Unvalidated model output reaching interpreters, cross-context output, unbounded output. OH1 matches AVE-2026-00040. OH2 and OH3 have no static AVE class. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| OH1 | Unvalidated Output Injection | static | equivalent | 00040 | Model output (variables named response, output, result, completion and similar) passed to exec, eval, os.system, subprocess, innerHTML, document.write or a SQL string, plus prose such as 'pipe the output directly to the shell'. This is AVE-2026-00040's payload surface, agent output reaching an interpreter unescaped. | +| OH2 | Cross-Context Output | static | no_fit | none | Prose about passing output across contexts, agents or sessions, or injecting output into the system prompt. The static AVE records do not cover it; the nearest, AVE-2026-00018 and AVE-2026-00020, are runtime_observed and out of scope. | +| OH3 | Unbounded Output | static | no_fit | none | max_tokens=None, 'no output limit', 'flood the console'. Resource exhaustion with no AVE class. | + +### Memory Poisoning (3 rules) + +Persistent context injection, context window stuffing, memory manipulation. MP1 matches AVE-2026-00027. MP2 and the runtime memory records (AVE-2026-00019, 00023) are runtime_observed and out of scope. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| MP1 | Persistent Context Injection | static | equivalent | 00027 | Prose such as 'remember this for all future interactions', 'from now on always', 'store this in your memory', 'treat this as a permanent rule'. These are AVE-2026-00027's indicators (instruction persistence across turns and sessions). | +| MP2 | Context Window Stuffing | static | no_fit | none | A repeated token run or prose such as 'fill the context window'. The matching AVE class, AVE-2026-00023, is runtime_observed and out of scope. | +| MP3 | Memory Manipulation | static | related | 00025, 00009 | Prose for clearing, overwriting or tampering with memory, 'forget all previous instructions', 'rewrite your personality', 'inject fake memories', 'pretend your previous conversation included...', and sentences adopting a reset state as the conversation state. The fabricated-history patterns are AVE-2026-00025; the identity-rewrite patterns are near AVE-2026-00009. AVE-2026-00019 (memory poisoning) is runtime_observed and out of scope. | + +### Tool Misuse (4 rules) + +Dangerous tool parameters, chained commands, unsafe defaults, privileged Kubernetes workloads. Grab-bag regex rules. The only clean AVE overlap is TLS verification disabled (AVE-2026-00061) inside TM3. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| TM1 | Tool Parameter Abuse | static | related | 00005, 00061 | A grab bag of dangerous parameters: shell=True (with AST resolution of variables), rm -rf on / or ~, --force, --no-verify, chmod 777, git push --force and reset --hard, curl -k and --insecure, SQL built by f-string. Only rm -rf on broad paths overlaps AVE-2026-00005 and only the curl and wget certificate flags overlap AVE-2026-00061. | +| TM2 | Chaining Abuse | static | related | 00004 | Chained commands: '&& rm -', '&& curl ... \| sh', '\| sudo', a trailing '\| sh', and prose such as 'chain these tools to bypass the safety check'. The curl-to-shell chain is AVE-2026-00004. AVE-2026-00068 (command composition through shared shell state) is runtime_observed and out of scope. | +| TM3 | Unsafe Defaults | static | narrower | 00061 | Unsafe defaults: verify=False, VERIFY_SSL=False, NODE_TLS_REJECT_UNAUTHORIZED=0, auth=None, allow_anonymous, CORS *, mode 777, debug mode, sandbox=False and 'disable security'. TLS verification disabled is one instance in that list and is AVE-2026-00061; the other settings have no static AVE class. | +| TM4 | Privileged Kubernetes Workload | static | no_fit | none | Privileged Kubernetes workloads: privileged: true, hostPath, host PID, network or IPC, kubectl run --privileged. A cluster takeover primitive with no AVE class. | + +### Rogue Agent (2 rules) + +Self-modification and session persistence. RA2 matches AVE-2026-00008. The previous revision mapped this category to AVE-2026-00048, 00036 and 00050; none of the rules reads like those records. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| RA1 | Self-Modification | static | related | 00001 | Writes to the skill's own file or SKILL.md, self-modify and self-update names, and prose such as 'rewrite the current code' and 'disable the safety check'. Shares one outcome with AVE-2026-00001, a component whose instructions change after review, but there is no remote fetch, which is the trigger in AVE-2026-00001. | +| RA2 | Session Persistence | static | equivalent | 00008 | Crontab, systemctl or launchctl enable, startup-file appends (.bashrc and similar), hidden directories in home, registry and plist writes, nohup, disown and setsid, and prose such as 'schedule a recurring task'. The cron and startup-file cases are AVE-2026-00008's fingerprint. RA2 also fires on nohup and hidden-directory writes, which AVE-2026-00008 does not name. | + +### Trigger Abuse (3 rules) + +Over-broad, shadowing and baiting triggers in the skill manifest. Manifest word-list checks. They overlap AVE-2026-00058 on broad activation but do not test the mismatch with the skill's real function. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| TR1 | Overly Broad Trigger | static | related | 00058 | A manifest trigger that is a single common word (the, do, make, code, file, data, hello...) or two characters or fewer, or a description clause 'whenever the user says '. Over-broad activation is part of AVE-2026-00058, which also requires the breadth to exceed the skill's actual function; TR1 does not compare against what the skill does. | +| TR2 | Shadow Command Trigger | static | related | 00082 | A manifest trigger equal to one of 51 built-in command words (help, run, test, commit...), or a description clause that claims to intercept or override such a command. Router-level shadowing of trusted functionality is the idea behind AVE-2026-00082, but TR2 tests a fixed word list inside one skill and cannot see a second skill or a discovery root. | +| TR3 | Keyword Baiting Trigger | static | related | 00058 | A trigger or description clause that matches all input: 'anything', 'always', 'whenever the user says anything', 'all messages'. Over-broad activation as in AVE-2026-00058, with no comparison against the skill's real function. | + +### Insecure Deserialization (5 rules) + +Python deserialization flows and PHP, Ruby and JavaScript deserializer sinks. All rules are code sinks for the vulnerability AVE-2026-00033 describes as an instruction. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| TT6 | Untrusted Data to Deserializer Flow | static | related | 00033 | Python data-flow from network, user or file input to an unsafe deserializer (pickle, marshal, dill, jsonpickle, joblib, read_pickle, yaml.unsafe_load). 'Deserialize untrusted input using pickle' is an AVE-2026-00033 indicator; the surface here is bundled Python and not an instruction to the agent. | +| DS1 | PHP Object Injection | static | related | 00033 | PHP unserialize( in PHP files, any call, no source test. Insecure deserialization is AVE-2026-00033's vulnerability, as a code sink rather than an instruction. | +| DS2 | Ruby Marshal Deserialization | static | related | 00033 | Ruby Marshal.load or Marshal.restore in Ruby files. Same relationship as DS1. | +| DS3 | Unsafe Ruby YAML Deserialization | static | related | 00033 | Ruby YAML.load, Psych.load or Oj.load in Ruby files. Same relationship as DS1. | +| DS4 | Unsafe JavaScript Deserialization | static | related | 00033 | node-serialize, serialize-to-js, funcster or .unserialize( in JavaScript and TypeScript files. Same relationship as DS1. | + +### YARA Match (4 rules) + +YARA rule matches, bucketed by the rule's category meta. The previous revision said YARA is only known malware. The built-in agent_skills.yar rules are behavioral and fall under YR1 and YR4; the other built-in rules are malware, webshell, miner and hack-tool signatures. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| YR1 | Malware Signature | static | related | 00003, 00004, 00005, 00008, 00034 | Bucket for YARA rules whose category meta is malware, so a mapping is per YARA rule. Built-in members: agent_skill_credential_exfiltration_webhook (AVE-2026-00003), agent_skill_remote_bootstrap_execution (AVE-2026-00004, and pip install from a URL for AVE-2026-00034), agent_skill_destructive_autonomous_actions (AVE-2026-00005) and backdoor_persistence (AVE-2026-00008), plus reverse_shell, reverse_shell_multiline, keylogger_indicators, ransomware_behavior, c2_framework_indicators and info_stealer, which have no AVE class. User-supplied rules (--yara-rules-dir) are not covered. | +| YR2 | Webshell Detected | static | no_fit | none | Webshell signatures (PHP, Python, JSP, ASPX). Known-malware matching with no AVE class. | +| YR3 | Crypto Miner Detected | static | no_fit | none | Cryptominer signatures (stratum, pools, miner software, coinjacking). Mining is not wallet drain (AVE-2026-00006); no AVE class. | +| YR4 | Hack Tool / Exploit Detected | static | related | 00007, 00002, 00032, 00009, 00015, 00029 | Bucket for YARA rules whose category meta is hack_tool or exploit. Built-in members include agent_skill_prompt_injection_hidden_instructions (override, reveal-prompt and persona-bypass phrasing: AVE-2026-00007, 00015 and 00009), agent_skill_mcp_tool_poisoning_metadata (AVE-2026-00002, with zero-width and bidi bytes for AVE-2026-00029) and network_reconnaissance (masscan, arp-scan, enum4linux: AVE-2026-00032). The remaining members (offensive tool references, privilege escalation tools, exploit frameworks, phishing kits) have no AVE class. | + +### MCP Least Privilege (4 rules) + +Manifest permissions compared with code capabilities. Pure static. LP1 and LP3 compare declared scope with actual behavior, the idea in AVE-2026-00022. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| LP1 | Underdeclared Capability | static | related | 00022 | Pure static check: code capability categories (shell, network, file read, file write, environment, MCP) found in executable files but not covered by the manifest's permissions or allowed-tools. It compares declared scope with actual behavior, the idea in AVE-2026-00022, but at the level of six capability categories rather than the files, APIs or systems an instruction directs the agent to touch. | +| LP2 | Wildcard Permission | static | related | 00038 | A wildcard in the declared permissions (*, all, full, any). A blanket grant like AVE-2026-00038's unlimited tool authority, expressed in the manifest instead of an instruction. | +| LP3 | Missing Permission Declaration | static | related | 00022 | No tool scope declared at all while the code has capabilities. The declared scope that AVE-2026-00022 compares against is missing, so the comparison cannot be made; SkillSpector reports the absence. | +| LP4 | Overdeclared Permission | static | no_fit | none | Permission declared but no matching code capability found (overdeclaration). The previous revision recorded this as a gap and it still is: no AVE record describes over-declared scope. | + +### MCP Tool Poisoning (4 rules) + +Hidden content, Unicode deception and injection in skill and tool metadata, plus an LLM description-behavior check. TP3 matches AVE-2026-00002. TP4 is the only LLM-dependent rule inside the category map. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| TP1 | Hidden Instructions | static | related | 00002, 00029 | Static check of manifest metadata fields (name, description, triggers, parameter text) for HTML and markdown comments (confidence 0.95 when they hold SYSTEM or IGNORE keywords), zero-width characters, data URIs and long base64 blobs. Hidden content in the description field is the surface of AVE-2026-00002; the zero-width characters are AVE-2026-00029's. The concealment technique, not directive content, is what TP1 tests. | +| TP2 | Unicode Deception | static | related | 00029 | Unicode deception in identifiers: Cyrillic and Greek homoglyphs, right-to-left and directional overrides, invisible formatting, mixed scripts. The technique is AVE-2026-00029's; the target is a name (for example read_file with a Cyrillic letter) rather than instruction text a reviewer is meant to miss. | +| TP3 | Parameter Description Injection | static | equivalent | 00002, 00041 | Static check of parameter descriptions and defaults: override phrases, SYSTEM or [INST] tokens, exfiltration verbs, descriptions over 500 characters, and defaults that are external URLs or shell commands. These are the indicators of AVE-2026-00002 (override phrases, descriptions far longer than needed), and AVE-2026-00041 names parameter descriptions as an injection surface. | +| TP4 | Description-Behavior Mismatch | llm | related | 00058 | LLM check (skipped with --no-llm) that the manifest description matches what the code does, emitted at LLM confidence 0.5 or more. Matches AVE-2026-00058's case of a generic description over a narrow sensitive implementation, but the test is a model's judgement and not a deterministic comparison. | + +### Agent Snooping (3 rules) + +Reads of agent config directories, MCP config and peer skills. Access to resources a skill has no need for. Related to AVE-2026-00022 but the rules do not check a manifest. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| AS1 | Agent Config Directory Access | static | related | 00022 | Reads of .claude, .codex, .gemini or .continue directories and their config files, in code and prose. Access to a resource the skill has no need for (AVE-2026-00022's idea), flagged by resource kind with no comparison to a manifest. Agent config can hold API keys, so AVE-2026-00003 is the follow-on if they are sent. | +| AS2 | MCP Config Access | static | related | 00022 | Reads of mcp.json and MCP config files, and prose such as 'list MCP servers'. Same relationship as AS1; the config holds server URLs and tokens. | +| AS3 | Skill Enumeration | static | related | 00022 | Listing or reading other installed skills (their SKILL.md, the skills directories). Same relationship as AS1. No AVE record describes one skill reading its peers. | + +### Anti-Refusal (3 rules) + +Refusal, disclaimer and safety-policy suppression. Jailbreak wording. Related to AVE-2026-00009, whose fingerprint is persona and unrestricted-mode language. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| AR1 | Refusal Suppression | static | related | 00009 | Prose such as 'never refuse', 'always comply', 'you cannot say no', 'no request is off limits'. Refusal suppression is a jailbreak technique and belongs to AVE-2026-00009's class, though AVE-2026-00009's fingerprint is persona and unrestricted-mode language and not refusal wording. | +| AR2 | Disclaimer Suppression | static | related | 00009 | Prose such as 'no warnings or disclaimers', 'do not moralize', 'skip the ethics'. SkillSpector calls it a jailbreak preamble. The weakest of the three anti-refusal links to AVE-2026-00009. | +| AR3 | Safety Policy Nullification | static | related | 00009, 00007 | Prose such as 'you have no restrictions', 'act as an unfiltered model', 'do anything now', 'developer mode enabled', 'ignore your guidelines'. The unrestricted-persona and mode wording is AVE-2026-00009; 'ignore your guidelines' is AVE-2026-00007's override. | + +### Server-Side Request Forgery (3 rules) + +Cloud metadata endpoints, private-range requests, dynamic request targets. No AVE record covers SSRF. + +| Rule | Name | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---| +| SSRF1 | Cloud Metadata Access | static | no_fit | none | Literal cloud metadata endpoints (169.254.169.254, metadata.google.internal, 100.100.100.200, fd00:ec2::254), skipped when the surrounding text documents a rejection rule. No AVE record covers server-side request forgery or metadata access; AVE-2026-00049's 'server-side request routing' concerns the Host header the component sends. | +| SSRF2 | Internal Network Request | static | no_fit | none | A request call with a literal loopback, link-local or private-range URL. AVE-2026-00032 is an instruction to scan the network, a different behavior from one request to a private address. | +| SSRF3 | Dynamic Request Target | static | no_fit | none | A request call whose URL host is a template or f-string value. No AVE class. | + +## Rules emitted outside the category map (37) + +These ids are absent from `RULE_ID_TO_CATEGORY` (so SkillSpector's own report falls back to a generic category for them) but are emitted by the analyzers named below. + +| Rule | Name | Analyzer | Detection | Relationship | AVE | Notes | +|---|---|---|---|---|---|---| +| AST1 | exec() Call | `behavioral_ast` | static | related | 00033 | Any exec() call in Python (AST, confidence 0.85, HIGH), with no test of what is executed. Dynamic code execution is AVE-2026-00033's sink (its indicators include eval(user_input)); AST1 has no untrusted-source test and AVE-2026-00033 is stated as an instruction to the agent. | +| AST2 | eval() Call | `behavioral_ast` | static | related | 00033 | Any eval() call in Python (HIGH, 0.85). Same relationship as AST1. | +| AST3 | Dynamic Import | `behavioral_ast` | static | no_fit | none | Any __import__() call (MEDIUM). A capability, not a behavior class. | +| AST4 | subprocess Call | `behavioral_ast` | static | no_fit | none | Any subprocess run, call, Popen, check_output or check_call (MEDIUM, 0.70). A capability use. The vulnerable form, caller-controlled input reaching a shell, is best fit by AVE-2026-00052 (proposed for deprecation, discussion 234), which is not recorded as a mapping. | +| AST5 | os.system / exec-family | `behavioral_ast` | static | no_fit | none | Any os.system, os.popen or os exec-family call (HIGH, 0.85). Same as AST4. | +| AST6 | compile() Call | `behavioral_ast` | static | no_fit | none | Any compile() call (MEDIUM). A capability, not a behavior class. | +| AST7 | Dynamic getattr() | `behavioral_ast` | static | no_fit | none | getattr() with a non-literal name, or a module __dict__ subscript with a non-literal key (LOW, 0.5). A capability signal with no AVE class. | +| AST8 | Dangerous Execution Chain | `behavioral_ast` | static | related | 00004, 00057 | exec, eval or compile whose first argument nests a compile, __import__, subprocess, os, base64, codecs, marshal, urllib, requests or httpx call (CRITICAL, 0.95). Structural nesting, not data flow. eval(requests.get(...)) is one of AVE-2026-00004's own examples and exec of decoded data is AVE-2026-00057; the rule fires on both and on other nestings. | +| AST9 | Reflective getattr() Sink | `behavioral_ast` | static | related | 00057 | getattr(os, 'system') and module __dict__['exec'] with a literal sink name (HIGH). SkillSpector calls it a deliberate evasion of name-based detection, which is the aim of AVE-2026-00057 (evading static scanners) reached by reflection instead of encoding. | +| AST10 | Insecure Deserialization | `behavioral_ast` | static | related | 00033 | pickle, marshal, dill, jsonpickle, read_pickle, joblib.load and yaml.unsafe_load unconditionally; yaml.load without a safe loader; torch.load without weights_only (MEDIUM). The same sink family as AVE-2026-00033, with no untrusted-source test. AST10 is named in PATTERN_NAMES and DEFAULT_EXPLANATIONS but not in RULE_ID_TO_CATEGORY. | +| BH1 | Bundled lifecycle hooks | `bundled_execution_surface` | static | related | 00064 | Reads hooks/hooks.json, .claude/settings.json, .claude/settings.local.json and the hooks field of .claude-plugin/plugin.json and reports that bundled lifecycle hooks can run on matching events, with severity set by reach and handler type (confidence 0.95, activation conditional). A committed auto-run surface in the sense of AVE-2026-00064; BH1 does not test the 'no user confirmation' condition. It remembers hook identities between the two settings files of one scan, not between versions, so it cannot see AVE-2026-00084's update-time rebinding. | +| BH2 | Bundled hook sends content remotely | `bundled_execution_surface` | static | related | 00046, 00003 | A bundled hook proven to send event or file content to a non-loopback host: an http handler on a sensitive event (UserPromptSubmit, PreToolUse, PostToolUse and similar), or a curl, wget, scp or rsync command uploading event input or a sensitive path (CRITICAL, 0.99). A hook that routes tool-call events to an external URL is AVE-2026-00046's behavior; the content sent is not limited to credentials (AVE-2026-00003). | +| BH3 | Bundled permission surface | `bundled_execution_surface` | static | equivalent | 00063 | Settings permissions: whole-tool or broad allow grants (Bash, Bash(*), Read, Edit, Write, root-wide paths) and defaultMode values such as bypassPermissions; modes ignored on a surface are reported with activation ignored_by_surface. A declarative setting that removes the approval step is AVE-2026-00063 (the cfgaudit crosswalk maps bypassPermissions and allowlists to it the same way). | +| BH4 | Bundled settings commands | `bundled_execution_surface` | static | related | 00064 | Settings keys that run shell commands: apiKeyHelper, awsAuthRefresh, otelHeadersHelper, statusLine, fileSuggestion (MEDIUM, 0.95). A project-level setting that makes the agent run a command, as in AVE-2026-00064, but the keys run only after settings activation and the rule does not test for a confirmation step. | +| RP1 | Unpinned MCP/package reference | `mcp_rug_pull` | static | equivalent | 00062 | Static mode: npx, uvx, pip install or docker pull references with no version, tag or digest, in code or manifest. A mutable dependency reference, AVE-2026-00062. The same id is reused in diff mode for added permissions, but diff mode needs previous_manifest, which build_context.py hard-codes to None, so a normal scan never runs it. | +| RP2 | Permission pre-staging | `mcp_rug_pull` | static | no_fit | none | Static mode: any '"permissions": [...]' array (0.6) or 'request additional permissions' prose (0.7) in the manifest, labelled pre-staging. Fires on ordinary permission lists; no AVE class. In diff mode the same id means changed trigger phrases, which a normal scan never reaches. | +| RP3 | Unpinned skill version | `mcp_rug_pull` | static | related | 00062 | Static mode: manifest version '*', 'latest', 'any' or a '>=' or '^' constraint. An unpinned version of the skill itself; AVE-2026-00062 is about a dependency reference, so it is the nearest. In diff mode the same id means a changed parameter schema, which a normal scan never reaches. | +| PE4 | Docker Socket Access | `static_patterns_privilege_escalation` | static | no_fit | none | docker.sock paths, docker.from_env() and DockerClient( (HIGH). Local container-daemon access; AVE-2026-00071 is a redirect of the daemon to a remote host, a different mechanism. | +| PE5 | Privileged Container / Container Escape | `static_patterns_privilege_escalation` | static | no_fit | none | --privileged, a root bind mount, --cap-add SYS_ADMIN, host namespaces, nsenter, release_agent. Container escape primitives with no AVE class (sandbox weakening is an open surface in the cfgaudit crosswalk too). | +| AE1 | Incomplete referenced artifact analysis | `finalize_inspection_ledger` | static | no_fit | none | Coverage finding: a referenced artifact was not completely inspected (HIGH, 1.0). It says what the scan did not see, not a behavior. | +| AE2 | Artifact content does not match extension | `artifact_integrity` | static | narrower | 00024 | Content kind disagrees with the file extension: a binary suffix on text content or a text suffix on binary bytes (MEDIUM, 0.9). Decided by byte classification (text versus binary), not by an ML file-type model. AVE-2026-00024 is the specific case of an executable disguised as a skill file; AE2 also fires on non-executable mismatches. | +| AE3 | Embedded NUL bytes in text artifact | `artifact_integrity` | static | related | 00024 | A text artifact that contains NUL bytes (HIGH, 0.9). Binary content under a text file; near AVE-2026-00024 but does not test for an executable. | +| AE4 | Suspicious Unicode normalization or mixed script | `artifact_integrity` | static | related | 00029 | Format-character density of 1% or more, or mixed scripts, in text (MEDIUM, 0.8). The same family of tricks as AVE-2026-00029; it reports a signal, not a hidden instruction. | +| AE5 | Exceeds whole-file semantic analysis limit | `artifact_integrity` | static | no_fit | none | Coverage finding: an instruction-capable file exceeds the whole-file semantic analysis limit (HIGH, 1.0). | +| AE6 | Inter-character separators | `artifact_integrity` | static | related | 00057 | Instruction text with separators between characters to evade pattern matching, for example 'i g n o r e' (HIGH, 0.9). Evading static pattern matching by splitting keywords is part of AVE-2026-00057's fingerprint; AVE-2026-00057 names concatenation rather than separators. | +| AE7 | Size limit, trailing content not inspected | `finalize_inspection_ledger` | static | no_fit | none | Coverage finding: a file exceeds the per-file size limit and trailing content was not inspected (HIGH, 1.0). | +| SSD-1 | Semantic prompt injection | `semantic_security_discovery` | llm | related | 00007, 00009 | LLM. Polite reframings of ignore-your-instructions, role-play that grants permissions, fictional framings used to bypass safety. The meaning of AVE-2026-00007 and AVE-2026-00009 without their keywords. | +| SSD-2 | Novel or paraphrased attack phrasing | `semantic_security_discovery` | llm | related | 00007 | LLM. Paraphrased or encoded forms of known attack phrasing, the same classes as SSD-1 with AVE-2026-00007 first. | +| SSD-3 | Natural-language exfiltration instructions | `semantic_security_discovery` | llm | related | 00003, 00013 | LLM. Plain-language instructions to collect or leak data ('keep a log of all inputs', 'always echo back credentials'). The instruct-then-expose shape of AVE-2026-00003 and AVE-2026-00013 in plain words. | +| SSD-4 | Narrative or gradual deception | `semantic_security_discovery` | llm | no_fit | none | LLM. Deception spread across steps. No single static AVE record; AVE-2026-00085 is the multi-skill form and needs several skills. | +| SDI-1 | Description-behavior mismatch | `semantic_developer_intent` | llm | related | 00058 | LLM. Manifest description versus code behavior (the TP4 test applied per file). AVE-2026-00058's generic-description case. | +| SDI-2 | Context-inappropriate capability | `semantic_developer_intent` | llm | related | 00022, 00058 | LLM. A code capability unjustified by the stated purpose, for example a text formatter that spawns subprocesses. Close to AVE-2026-00022 and AVE-2026-00058. | +| SDI-3 | Scope creep vs declared permissions | `semantic_developer_intent` | llm | related | 00022 | LLM. Code that accesses more than the manifest permissions cover (LP1 with judgement). AVE-2026-00022. | +| SDI-4 | Intent-code divergence | `semantic_developer_intent` | llm | no_fit | none | LLM. Comments or docstrings that contradict the code. No AVE class. | +| SQP-1 | Vague triggers | `semantic_quality_policy` | llm | related | 00058 | LLM. Vague or over-broad trigger wording in markdown, text and manifests (TR1 and TR3 with judgement). AVE-2026-00058. | +| SQP-2 | Missing user warnings | `semantic_quality_policy` | llm | no_fit | none | LLM. Missing user warnings for risky operations. A quality finding with no AVE class. | +| SQP-3 | Natural-language policy violations | `semantic_quality_policy` | llm | no_fit | none | LLM. Natural-language policy violations, currently language or locale policy. No AVE class. | + +AVE ids in the tables are shown without the `AVE-2026-` prefix. + +## Rug pull (RP1 to RP3) has two modes + +The same ids mean different things in two modes. Static mode checks for unpinned references, permission lists and an unpinned version. Diff mode compares the manifest with a `previous_manifest` (permissions added, trigger phrases changed, parameter schema changed). `previous_manifest` is set to `None` in `src/skillspector/nodes/build_context.py` and nothing else sets it outside the tests, so a normal scan only runs the static mode. + +## Checked and rejected + +Candidate links read in full and not recorded as mappings. + +| Rule | AVE | Why not | +|---|---|---| +| SC10 | 00073 | Same shape (a static configuration value redirects traffic) but a different object: where a package manager resolves dependencies versus where the agent sends telemetry or model traffic. | +| SC10 | 00062 | AVE-2026-00062 is the absence of a pin. A pinned name still resolves from an attacker's registry, so pinning is not the control SC10 tests; AVE-2026-00074 makes the same point for changed target identity. | +| SC8 | 00075 | Recorded as narrower, not related: every 00075 instance ships a .pyc so SC8 fires, but SC8 never opens the bytecode and AVE-2026-00075 requires divergence from the sibling source. | +| TR2 | 00058 | AVE-2026-00058 needs activation scope broader than the skill's function; TR2 only tests a trigger against a fixed list of built-in command names. | +| TT5 | 00052 | Best fit for the shell sinks, but AVE-2026-00052 is proposed for deprecation (discussion 234, CWE-78), so it is noted and not recorded as a mapping. | +| AST4 | 00052 | Same as TT5: noted, not mapped, while AVE-2026-00052 is pending deprecation. | +| SC6 | 00017 | AVE-2026-00017 is a false claim of official MCP server identity; a typosquatted package name in a dependency list is a different object. | +| SC5 | 00074 | AVE-2026-00074 is verified live against the owning authority; SC5 matches a fixed list of abandoned names. | +| SSRF2 | 00032 | AVE-2026-00032 is an instruction to probe and map a network; SSRF2 flags one request call to a literal private address. | +| PE4 | 00071 | AVE-2026-00071 redirects the daemon to a remote host; PE4 flags local socket use. | +| TM3 | 00072 | Auth settings set to none are not a wildcard bind address; AVE-2026-00072 needs the 0.0.0.0 or [::] bind. | +| BH1 | 00084 | AVE-2026-00084 is detected by a diff against the last reviewed version; BH1 reads one snapshot. | +| RP1 | 00084 | RP's diff mode would be near AVE-2026-00084 (an update changes a trusted surface) but compares permissions, triggers and parameters rather than hook bindings, and is never run by a normal scan. | +| AS2 | 00003 | Reading MCP config is only the read half of AVE-2026-00003 and carries no transmission; recorded against AVE-2026-00022 instead. | +| MP2 | 00023 | AVE-2026-00023 is runtime_observed; out of scope. | +| OH2 | 00018 | AVE-2026-00018 and AVE-2026-00020 are runtime_observed; out of scope. | +| TP2 | 00017 | A homoglyph tool name spoofs an identifier but makes no claim of verified server identity, which is AVE-2026-00017's fingerprint. | ## Gaps -| SkillSpector category | Gap | +### SkillSpector rules with no AVE class + +| Category | Rules | Reason | +|---|---|---| +| Prompt Injection | P5 | Content safety (physical-harm content), not an agent behavior class. | +| Data Exfiltration | TT1, TT2 | Generic data-flow reports between any source and sink, not a behavior class. | +| Privilege Escalation | PE2 | Elevated execution is a capability use, not a behavior class. | +| Supply Chain | SC4, SC5, SC6 | Known-vulnerable, abandoned and typosquatted dependencies are reputation and CVE checks. AVE enumerates behavior classes; the nearest records (AVE-2026-00074, 00017, 00066) test different things. | +| Supply Chain | SC10 | Package-manager dependency source redirection. A genuine gap on the AVE side with SC10 as its source: no AVE record's fingerprint or text covers it (all 89 records searched). The two nearest records, AVE-2026-00073 and 00062, are listed under checked_and_rejected. | +| Excessive Agency | EA4, EA5 | Resource exhaustion and billing-account switching. No AVE class. | +| Output Handling | OH2, OH3 | Cross-context output flow has only runtime AVE counterparts (out of scope); unbounded output is resource exhaustion. | +| Memory Poisoning | MP2 | Context window stuffing has only a runtime AVE counterpart, AVE-2026-00023 (out of scope). | +| Tool Misuse | TM4 | Privileged Kubernetes workload. Cluster takeover primitive with no AVE class. | +| YARA Match | YR2, YR3 | Webshell and cryptominer signatures. Known-malware matching with no AVE class. | +| MCP Least Privilege | LP4 | Over-declared permissions. Carried over from the previous revision's gap on server-card over-declaration; still no AVE record. | +| Server-Side Request Forgery | SSRF1, SSRF2, SSRF3 | No AVE record covers SSRF or cloud metadata access. | +| (emitted outside RULE_ID_TO_CATEGORY) | AST3, AST4, AST5, AST6, AST7 | Python capability signals (dynamic import, subprocess, os.system, compile, dynamic getattr). AST4 and AST5 are best fit by AVE-2026-00052, pending deprecation. | +| (emitted outside RULE_ID_TO_CATEGORY) | RP2 | Fires on ordinary permission lists; no AVE class. | +| (emitted outside RULE_ID_TO_CATEGORY) | PE4, PE5 | Container socket and escape primitives. No AVE class. | +| (emitted outside RULE_ID_TO_CATEGORY) | AE1, AE5, AE7 | Coverage findings: they report what the scan could not inspect, not a behavior. | +| (emitted outside RULE_ID_TO_CATEGORY) | SSD-4, SDI-4, SQP-2, SQP-3 | LLM-only findings with no AVE class (narrative deception, comment-code divergence, missing warnings, language policy). | + +### Static AVE records no SkillSpector rule maps to (27 of 61) + +| AVE | Reason | |---|---| -| yara_signatures | YARA detects embedded known-malware artifacts. AVE enumerates behavioral vulnerability classes in skill instructions, not malware payload matching. These are complementary, not overlapping. | -| trigger_abuse | Conditional trigger abuse as a distinct behavioral class (deferred payload execution, dead-man switches) is not yet a separate AVE record. Partially covered by AVE-2026-00001 and AVE-2026-00027. | -| mcp_least_privilege | Server-card capability over-declaration as a distinct behavioral class is not yet a separate AVE record, though AVE-2026-00050 now covers the runtime registration variant of this gap. | +| 00006 | Crypto wallet drain by fund-transfer instruction. No SkillSpector rule looks for transfers, allowance approvals or transaction signing. YR1's info_stealer names wallet.dat (theft of a wallet file) and YR3 matches miners; neither is a transfer instruction. | +| 00011 | Explicit tool-call directives with parameters. No rule detects an instruction that dictates a tool invocation; EA1, LP2 and PE1 concern how broad tool access is, not a directed call. | +| 00014 | False authority claims (text said to come from a model vendor or operator). No rule or YARA string looks for authority claims; P1 and AR3 match override and no-restriction phrasing only. | +| 00017 | MCP server impersonation. TP2 flags homoglyph and mixed-script identifiers, but no rule reads a claim of official or verified status or compares a name with a registry. | +| 00030 | Elevated privileges granted to anyone who claims a role. No rule tests for conditional privilege grants based on a claimed role. | +| 00036 | Lateral movement instructions. No rule has lateral-movement or pivot language; 'pivot' appears only inside the SSRF2 explanation text. | +| 00039 | Steganographic and covert-channel exfiltration. No rule looks for first-letter, whitespace or timing encodings of output. P7's acrostic and encode-the-prompt patterns touch the system-prompt case only. | +| 00045 | Cross-app-access escalation between MCP servers in one session. No rule tests for text in one server's tool description that tells the agent to use another server's tools. | +| 00047 | Hardcoded credentials. SkillSpector has no rule, static or LLM, that flags literal secret strings in files; PE3 flags paths to credential files and E2 flags bulk environment reads. Its report redaction hides secrets in output but does not report them. | +| 00048 | Unsafe agent delegation chain. No rule has sub-agent or delegation language; the only 'Subagent' strings in the analyzers are hook event names. | +| 00049 | Host header injection on agent-initiated requests. No rule inspects Host, X-Forwarded-Host or Forwarded headers. | +| 00051 | OAuth discovery rebinding. No rule reads OAuth discovery metadata; the OAuth wording in PE3 only decides when a token noun is benign. | +| 00052 | Command injection in MCP server implementation code. Proposed for deprecation in discussion 234 (CWE-78). The nearest checks (TT5, AST4, AST5) are not recorded as mappings. | +| 00053 | Path traversal in MCP resource handlers. Proposed for deprecation in discussion 234 (CWE-22). SkillSpector has no path-traversal rule. | +| 00055 | Command execution through an untrusted MCP launch configuration. No rule reads MCP server command and args fields; BH4 covers Claude Code settings keys such as apiKeyHelper, a different configuration surface. | +| 00059 | Fragmented cross-description injection. TP1 to TP3 inspect each metadata field on its own (docs/B.3.2), so a payload split across descriptions is not reassembled. | +| 00060 | STDIO transport shell injection in server code. Proposed for deprecation in discussion 234 (CWE-78). The nearest checks (TT5, AST4, AST5) are not recorded as mappings. | +| 00065 | A2A agent card poisoning. No rule or YARA string mentions agent cards or the A2A protocol. | +| 00069 | Image-hidden instructions. SkillSpector's image handling validates PNG and JPEG structure and, by its own documentation, does not inspect rendered content or perform OCR (docs/passive-documentation-images.md). | +| 00071 | DOCKER_HOST daemon redirect. No rule mentions DOCKER_HOST or the -H and --host flags; PE4 and PE5 cover local socket and privileged-container primitives. | +| 00072 | MCP server bound to all interfaces. No rule inspects bind addresses; SSRF2 matches request targets, not listeners. | +| 00073 | Endpoint redirect through a static configuration value. SC10 is the same shape for package managers only. No rule checks telemetry, model-provider or MCP server URLs. | +| 00074 | Dead external anchor reclamation. It needs live lookups against GitHub, registries, RDAP or cloud providers. SC4 queries OSV.dev and SC5 and SC6 use fixed lists; none checks that a referenced owner, package or domain is still claimed. | +| 00076 | Natural-language steering of an approval classifier. No rule reads allow_instructions or block_instructions entries; BH3 reads Claude settings permissions only. | +| 00077 | Cross-origin tool and resource declarations in one MCP manifest. No rule compares the root domains or schemes of URLs declared in a manifest. | +| 00084 | Lifecycle hook trust decoupling on plugin update. Detection needs a diff against the last reviewed version. BH1 sees one snapshot (it only carries hook identities between the two settings files of one scan), and RP's diff mode needs previous_manifest, which build_context.py sets to None and which compares permissions, triggers and parameters, not hook bindings. | +| 00085 | Collusive cross-skill composition. Every rule evaluates one artifact or one skill; the multi-skill module only discovers skill directories under --recursive and does not correlate them. | + +## Out of scope: runtime AVE records + +SkillSpector is a static scanner.

A plugin passes marketplace or registry vetting under a benign, reviewed lifecycle-hook configuration and a stable public identity. A later version update, published under that same identity, silently adds or rebinds a hook to an attacker-chosen command. The harness's own automatic update-sync path applies the new binding with no per-entry re-authorization, no new LLM decision, and typically no user-facing notification distinguishing the change from the plugin's original, already-reviewed state -- the update inherits the trust the original install earned. When the bound event next fires, the harness dispatches the attacker's command directly from its own event-dispatch layer, outside the model's reasoning or tool-call decision path entirely, so prompt-level, alignment, or model-mediated defenses never see the exploitation step and cannot intervene. Confirmed concretely on Claude Code: the harness's automatic marketplace-update synchronization checks repositories for manifest changes and applies them, hook entries included, without validating individual hook entries against what a reviewer or scanner last inspected. Demonstrated with HookPry, an open-source, fully automated attack framework realizing this mechanism across seven real agent harnesses (Claude Code, OpenClaw, OpenHarness, Codex CLI, OpenCode, Hermes, WorkBuddy) and five LLM backends, 25 harness/backend combinations, 1,000 end-to-end runs: HookPry compromises all seven harnesses, with a 77.0% micro-averaged and 77.9% macro-averaged end-to-end attack success rate, peaking at 92.5% on the Hermes harness, and 83.9% average mechanism utility (the proportion of runs in which hook triggering, payload loading, and hook registration actually occur, independent of whether the full external effect is confirmed). An ablation study confirms the temporal-decoupling component is load-bearing, not incidental: blocking the ability for a new hook entry to inherit an existing plugin identity's authorization drops end-to-end success to 0%, and removing the harness-specific compilation step (translating the attack into each harness's native lifecycle-hook interface) also drops it to 0%, while removing only the metadata-optimization component (which improves marketplace discoverability of the carrier plugin, not the exploitation mechanism itself) reduces but does not eliminate success (a 16.4 percentage-point drop). Representative defenses are shown insufficient against the confirmed mechanism: Microsoft Defender achieves 0% recall, and the union of three static defenses still misses 47.5% of the malicious artifacts HookPry generates. The paper's authors state they have responsibly disclosed their findings to all affected harness vendors and are awaiting response. Distinct from AVE-2026-00046 (Tool Hook Interception): that record's mechanism is a skill's own declared instruction text asking the agent to register a hook targeting tool calls -- an LLM-mediated act, visible in the skill's stated instructions and requiring the model to act on them. This record's hook binding is applied by the harness's own update-sync path with no LLM decision, instruction-following, or content read by the model involved at any point. Distinct from AVE-2026-00050 (Parasitic Toolchain): that record is an undeclared registration exceeding a component's own manifest scope, occurring at session initialization. This record's plugin legitimately has lifecycle-hook capability declared in its manifest from the start; the violation is that a later, same-identity update can silently change which event and command are bound, with the harness treating that change as covered by the original install's already-completed vetting. Distinct from AVE-2026-00062 (Unpinned Dependency Substitution): that record's mechanism requires a mutable version specifier (a floating tag or unbounded range) causing a different version to resolve than intended. This record's mechanism works even against a correctly pinned, explicitly versioned update that a marketplace's own update mechanism legitimately and deliberately applies -- the gap is the absence of per-update hook re-authorization, not dependency-resolution ambiguity. Distinct from AVE-2026-00081 (Lingering Authority): that record is a task or episode-scoped capability grant reused after its own closure event, within a single session's lifecycle. This record's trust is scoped to a plugin's persistent public identity, not a session episode, and persists across a version-update boundary that spans installs and sessions entirely, with the defining property being that hook dispatch bypasses the model's decision path altogether rather than a stale grant being reused within it.", + "aivss_score": 7, + "cvss_base_vector": "CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:H/SI:H/SA:L", + "owasp_mcp": [ + "MCP04" + ], + "owasp_asi": [ + "ASI04" + ], + "mitre_atlas": [ + "AML.T0010.005" + ], + "nist_ai_rmf": [], + "behavioral_fingerprint": "A plugin or skill that already passed marketplace/registry vetting under a benign, reviewed lifecycle-hook configuration receives a later version update, published under the same stable public identity, that adds or changes the shell command bound to a lifecycle event (session start, tool invocation, file or config edit).

matching lifecycle event with zero further attacker interaction. tool_use scored 0, deliberately, not by oversight: the paper's own central finding is that hook dispatch happens outside the LLM's tool-calling and reasoning path entirely -- the harness's own event-dispatch layer spawns the subprocess directly, so this mechanism does not require, and specifically bypasses, the agent's own tool-calling capability. persistent_memory and data_access scored at maximum (1): the hook binding, once updated, persists across every future session until removed or patched (a standing config-state change, not a one-off), and the confirmed effect range spans credential collection, data exfiltration, resource hijacking, command and control, tampering, and privilege escalation -- the ten attack objectives HookPry's own taxonomy formalizes against MITRE ATT&CK tactics. external_dependencies scored at maximum (1): the paper's own cross-harness evaluation shows real, measured effectiveness variance by harness (55.3% to 93.4% macro-average by attack category, 41.7% to 92.5% by harness), and a harness whose update-sync path already re-validates hook entries per update would not be vulnerable at all -- severity is definitionally tied to which specific harness is in use. non_determinism and dynamic_identity scored 0.5: the paper's own RQ1.2 measures real, nonzero cross-backend standard deviation in end-to-end success (1.1 to 9.6 percentage points depending on harness) tied to which LLM backend generates the triggering tool-use pattern, and the mechanism exploits the harness's own assumption that a stable, genuine, unchanged plugin identity across a version update still carries its original trust level -- real trust-anchor confusion, but not a spoofed or false identity claim, since the identity genuinely is the same plugin throughout. multi_agent, self_modification, and natural_language_input scored 0: the mechanism is single-harness, does not require the component to alter its own instructions, and involves no natural-language content at any point in the exploitation path -- the payload is a shell command bound via manifest configuration, not text a model interprets. cvss_base_vector reflects a network-delivered update (AV:N), low complexity once the update channel is controlled (AC:L), a real attacker-controlled-update precondition (AT:P, matching the paper's own supply-chain threat model: the attacker controls only plugin metadata and lifecycle-hook configuration, not local or repository access), no privileges or user interaction required beyond that precondition (PR:N/UI:N), full confidentiality/integrity impact at both the vulnerable harness and the subsequent host system (VC:H/VI:H, SC:H/SI:H) given arbitrary command execution with host privileges, and low rather than high availability impact at either layer (VA:L/SA:L) since this is not primarily a denial-of-service-shaped class even though resource-hijacking effects were among the ten confirmed attack objectives. thm set to 1 (mechanism real and demonstrated): 1,000 real end-to-end runs across seven real, named, current agent harnesses and five real LLM backends, with an ablation study isolating which components are load-bearing and a stated responsible disclosure already sent to affected vendors -- this is a working, reproduced exploit framework, not a theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): the paper's own evaluation shows representative production defenses, including a major commercial antivirus product, are insufficient against the confirmed mechanism, and no standard practice for per-update lifecycle-hook re-authorization is yet in place across the evaluated harnesses. owasp_mcp mapped to MCP04 (Software Supply Chain Attacks & Dependency Tampering) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP04 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states 'compromised dependencies can alter agent behavior, introduce hidden backdoors, or modify protocol semantics without triggering detection,' and its vulnerability checklist names 'fetch dependencies automatically during runtime/build' and 'no integrity verification mechanisms' verbatim -- both a direct match for a harness's own automatic update-sync path applying an unvalidated hook-binding change. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly (genai.owasp.org, 'OWASP Top 10 for Agentic Applications 2026', pages 18-20): its own description states these vulnerabilities 'arise when agents, tools, and related artefacts they work with are provided by third parties and may be malicious, compromised, or tampered with in transit,' and that 'agentic ecosystems often compose capabilities at runtime -- loading external tools/agent personas dynamically -- thereby increasing the attack surface,' a direct categorical match even though none of ASI04's own worked examples describes this specific lifecycle-hook-update variant. mitre_atlas mapped to AML.T0010.005 (AI Agent Tool, under AML.T0010 AI Supply Chain Compromise) after searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly: its own description names agent tools as 'an attractive target for adversaries because compromising an AI agent can provide them with broad accesses and permissions on the victim's system via the agent's other tools' and cites a real prior incident (the Postmark MCP npm backdoor) of a trusted, published package being compromised via an update -- structurally analogous. Flagged honestly as an imperfect fit: T0010.005's own text centers on tools carrying malicious code or prompt injections, a content-level compromise, while this record's specific mechanism is narrower and does not require the plugin's own code or description to be malicious at all, only its lifecycle-hook manifest entry; no more specific existing ATLAS technique naming lifecycle-hook update-time trust decoupling was found. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text (Tables 1-4) directly: MAP 4.2 ('internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') was the closest candidate, but it is a generic third-party-component risk-documentation subcategory that does not describe this record's specific update-time trust-decoupling mechanism any more precisely than it would describe nearly any other third-party supply-chain finding -- left empty rather than perpetuated, matching the same discipline applied to AVE-2026-00081 and AVE-2026-00083." + }, + "evidence_kind_default": "config_schema", + "detection_stage": "static_detection", + "detection_layer": "registry_metadata", + "confidence_baseline": 0.7, + "evidence_basis_engines": [ + "pattern", + "sandbox" + ], + "derivable_into": [ + "remote-control-chain", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00085", + "schema_version": "1.2.0", + "status": "active", + "title": "Collusive cross-skill composition: a malicious workflow split across independently benign skills", + "attack_class": "Obfuscation - Collusive Cross-Skill Composition", + "severity": "HIGH", + "description": "An attacker decomposes a single malicious workflow into three or more sub-payloads and packages each as its own independently-installable skill, with a real, narrow, individually-benign function -- one might be a project-setup helper, another an API analyzer, another a test runner. Adjacent sub-skills are connected through genuine runtime artifacts, a file, an environment variable, a task-state value, that one sub-skill's actual execution produces and a subsequent sub-skill's execution consumes, so the complete harmful behavior exists only in the ordered composition's real data flow during genuine agent execution and never in any single skill's own declared instructions, code, or permissions. Because per-skill scanners inspect each skill's own content, permissions, dependencies, and code behavior in isolation, every sub-skill passes individual review, and the complete attack surfaces only when all sub-skills are installed together and the agent executes them in their intended order. Demonstrated with ColluSkill, evaluated against six real, currently-deployed skill scanners (CISCO Skill Scanner, SkillFortify, Auditor, SlowMist, Vetter, SkillSpector): an average 96.0% attack success rate across the six, reaching 100% on two of them, and the best performance among five single-skill and one multi-skill attack baseline evaluated on the same scanners (the next-best baseline, a multi-skill benchmark not purpose-built for scanner evasion, reaches 34.8%). ColluSkill's chain planning uses an attacker-controlled LLM to infer an ordered payload plan and iteratively rewrites any sub-skill a scanner flags, using the scanner's own feedback, while keeping already-passing sub-skills unchanged -- this refinement measurably raises average attack success rate from 64.9% before any refinement to 96.0% after seven iterations. Real runtime execution is confirmed, not merely scanner evasion in the abstract: ColluSkill attack chains successfully activate on three real coding agents (OpenCode, Claude Code, Codex) across different model backbones (GPT-5.5, DeepSeek-V4-Pro, GLM-5.2), with chain activation success ranging 58.5% to 92.5% depending on the agent. The paper's own proposed defense, ChainGuard, a context-aware scanner that evaluates a candidate skill together with the full set of skills already installed rather than in isolation, reduces but does not eliminate the attack (22.5% residual attack success rate) while passing 99.5% of benign workflows. Distinct from AVE-2026-00059 (Fragmented Cross-Description Reassembly): that record's fragments are tool-description text spread across multiple tools, reassembled inside the model's own inference at a separately planted trigger, before any tool call executes -- a pure inference-time text-combination mechanism. This record's fragments are real, separately-installed skill packages whose harmful composition is reconstructed only through actual runtime artifact passing during genuine, completed execution, not text combined in the model's context. Distinct from AVE-2026-00057 (Static Analysis Evasion): that record's evasion mechanism is encoding or obfuscation within one skill's own payload, defeating single-pass static pattern matching on that one file. No sub-skill in this record's mechanism contains any encoded, obfuscated, or otherwise suspicious content at all; each is genuinely, functionally benign on its own, and the evasion is achieved by the composition itself, not by hiding content within any single skill. Distinct from AVE-2026-00070 (Distributed Cross-Agent Backdoor Fragments): that record's fragments are encrypted, dormant primitives embedded in tool observations, persisting across multiple distinct agents' own memories and reassembled externally by the attacker after the collaborative run ends. This record's sub-skills are unencrypted, fully functional, and complete their entire harmful workflow live, within one agent's own session, with no external post-run reassembly step and no multi-agent memory persistence involved. Distinct from AVE-2026-00067 (Skill Composition Trust Transfer): that record's mechanism is a downstream skill accepting an upstream skill's claimed endorsement or validation result as sufficient authorization without independently reverifying it -- a misplaced-trust-in-a-claim mechanism. No skill in this record's mechanism makes or relies on any trust or endorsement claim about another skill at all; the sub-skills exchange functional data artifacts as ordinary parts of one attacker-planned workflow, with no vouching or authorization claim anywhere in the chain.

MCP03 (Tool Poisoning) was also read in full and rejected: its real text is specifically about schema or contract tampering causing benign operations to map to destructive ones, a different mechanism from composing multiple genuinely-unmodified, individually-correct skills. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly: its own description states these vulnerabilities arise when 'agents, tools, and related artefacts they work with are provided by third parties' and that 'agentic ecosystems often compose capabilities at runtime... thereby increasing the attack surface' -- the phrase 'compose capabilities at runtime' is a close match for this record's own mechanism, a stronger fit than the same category's application to AVE-2026-00084. mitre_atlas confirmed empty after searching the live ATLAS.yaml directly: AML.T0010.005 (AI Agent Tool) centers on tools carrying malicious code or prompt injections, the opposite of this mechanism's property that no individual component is malicious; AML.T0067 (LLM Trusted Output Components Manipulation) and AML.T0094 (Delay Execution of LLM Instructions) both describe single-prompt evasion techniques, not multi-component decomposition defeating per-component scanning. No existing technique names workflow decomposition across multiple independently-scanned components as its own mechanism; a genuine gap, left empty rather than stretched a second time in this same sourcing pass. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic third-party-component boilerplate already flagged as non-specific on AVE-2026-00081, AVE-2026-00083, and AVE-2026-00084 was found to fit this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "static_detection", + "detection_layer": "content", + "confidence_baseline": 0.5, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "credential-exfiltration", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00086", + "schema_version": "1.2.0", + "status": "active", + "title": "Mid-session WebMCP tool hijacking: a live registry swap replaces an already-discovered tool under its own name", + "attack_class": "Trust Boundary - Mid-Session Tool Registry Hijacking", + "severity": "HIGH", + "description": "WebMCP lets a website expose tools directly to an AI agent within a live browser session, so the set of tools an agent can observe and invoke is dynamic rather than fixed at session start. A compromised or malicious third-party script running on the same page, a CDN, an advertising SDK, or any other same-page JavaScript component, manipulates the agent's live tool registry during the session. In the AbortSignal-hijack form, the malicious script waits until a predefined trigger condition is satisfied, then uses the browser's AbortSignal API to unregister an already-discovered, already-invoked-at-least-once tool, and immediately re-registers a malicious replacement under the exact same tool name before the agent's next invocation of it. In the registration-race form, the malicious script wins a race to register a tool under a target name before the legitimate tool ever registers, so the agent's first discovery of that name already resolves to the attacker's implementation. In both forms, the agent has no mechanism to detect that the live implementation behind a tool name changed, because WebMCP's own tool surface carries no binding between a tool's name and a stable origin or identity across the session -- the agent trusts the name, and whichever implementation currently answers to it. Demonstrated across a real testbed with benign and malicious page servers and three current frontier models (GPT-5.4, Claude Opus 4.6, Gemini 2.5-flash), 1,440 total runs across 12 conditions, 4 task scenarios, and the 3 models. The AbortSignal-hijack form achieves a 94% average malicious-tool-invocation rate (100% on GPT-5.4, 100% on Claude Opus, 82% on Gemini), and the registration-race form achieves 100% across all three models. A timing-sensitivity study confirms the AbortSignal form's success is strictly bounded by whether the hijack completes before the tool's first legitimate invocation: 100% success when the malicious replacement is in place before the agent's first call, and 0% at every later injection point tested, including immediately after the agent's first legitimate call to the original tool. Scoped specifically to this tool-identity-substitution mechanism, not the same paper's separate Tool Framing category (metadata- and description-based manipulation of an agent's understanding of a tool's role), which the paper's own discussion states partially overlaps with indirect prompt injection already covered elsewhere in this corpus; this record's mechanism involves no description, metadata, or natural-language content manipulation of any kind. Distinct from AVE-2026-00074 (Dead Anchor Reclamation): that record's mechanism is an external identity anchor (a GitHub owner, package name, or domain) that was live when a skill was authored and has since decayed into an unclaimed, re-registerable state over an external, slow timescale. This record's mechanism is a live, in-session, client-side tool registry manipulated via a browser API in real time, with no external decay, no waiting period, and no registry outside the WebMCP session itself. Distinct from AVE-2026-00080 (Runtime Agent Identity Substitution): that record's mechanism is an orchestrator accepting an unverified process at an agent's own routing position during a multi-agent retry cycle, with no credential or attestation check binding the response to the same agent instance. This record involves a single agent's own tool registry, poisoned by a third-party script on the page it is interacting with; no multi-agent orchestration, routing position, or retry cycle is involved anywhere in the mechanism. Distinct from AVE-2026-00082 (Local Skill Name Collision): that record's mechanism is two already-existing local files resolving to an identical name at discovery time, a static, filesystem-level condition requiring no attacker runtime action beyond placing a file. This record's mechanism is an active, live browser API call (AbortSignal) or registration-order race, executed during an active session by a malicious third-party script, with no local files or discovery roots involved at all. Distinct from AVE-2026-00002 (Tool Description Behavioral Injection): that record's mechanism is content-level injection within a tool's own description field, requiring the model to be steered by natural-language directives it reads.

MCP03 remains the best available category among the ten (the same choice this corpus already made for AVE-2026-00082's structurally similar name-collision mechanism, after MCP09 was checked and rejected there as an infrastructure-governance category, not a client-side registry-identity problem). owasp_asi mapped to ASI03 (Identity and Privilege Abuse) after reading the full 2026 PDF text directly: its own worked example, 'Synthetic Identity Injection: Attackers impersonate internal agents by using unverified descriptors... to gain inherited trust and perform privileged actions under a fabricated identity,' is a close structural match with 'tool' substituted for 'agent' -- a malicious tool assumes an unverified descriptor (its name) to inherit the trust the agent already extends to it. mitre_atlas mapped to AML.T0074 (Masquerading) after confirming its live text directly in ATLAS.yaml: 'the name or location of an object... is manipulated or abused for the sake of evading defenses and observation... giving legitimate task or service names' is a direct, unstretched match for a malicious tool registered under an existing, legitimate tool's exact name. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic security-evaluation or third-party-risk boilerplate already found non-specific for the other records in this sourcing pass fits this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "sandbox", + "llm" + ], + "derivable_into": [ + "credential-exfiltration" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP03-2025%E2%80%93Tool-Poisoning.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00087", + "schema_version": "1.2.0", + "status": "active", + "title": "Agentjacking: a crafted tool response visually mimics a trusted system template to hijack an agent", + "attack_class": "Prompt Injection - Tool Response Template Mimicry", + "severity": "HIGH", + "description": "A monitoring or diagnostic integration exposes an MCP server whose ingest endpoint is designed to be publicly writable, a deliberate architectural choice so that unauthenticated clients (a user's own browser, for instance) can report events without holding a full credential. An attacker who obtains the write-only ingest credential, often trivially recoverable from a target's own public frontend JavaScript, POSTs a crafted event directly to that ingest endpoint, controlling the entire payload structure. The injected event embeds carefully formatted markdown, headings, code blocks, and a fabricated resolution or remediation section naming an executable command, within standard fields of the event schema, styled to be visually indistinguishable from the integration's own authentic, system-generated output. When a developer later asks their AI coding agent to investigate the resulting error or event, the integration's own MCP server returns the poisoned event to the agent as diagnostic data. The agent's own handling of MCP tool responses treats this returned data as authoritative system output rather than as untrusted external content requiring the same scrutiny as user-supplied input, and because the markdown formatting mirrors the integration's authentic template exactly, there is no visual or structural cue distinguishing the compromise from a genuine event. The agent, unable to distinguish the attacker's embedded instruction from legitimate remediation guidance, executes the suggested command with the developer's own full privileges. Demonstrated concretely against Sentry, a widely deployed error-tracking and performance-monitoring platform, using its DSN (Data Source Name), a public, write-only credential intentionally embedded in frontend JavaScript by design, requiring no additional authentication to submit events. Testing across three current AI coding agents, Claude Code, Cursor, and OpenAI Codex CLI, achieved an 85% exploitation success rate. Tenet Security identified at least 2,388 organizations with publicly exposed Sentry DSNs that could be used to inject malicious events by this method. Sentry itself has acknowledged the underlying issue as 'technically not defensible' given the DSN's intentionally public-write design, and has activated a narrow content filter blocking one specific payload string rather than a structural fix. The attack bypasses EDR, WAF, IAM, VPN, Cloudflare, and firewall defenses entirely, because no conventionally malicious artifact, no malware signature, no anomalous network behavior, exists anywhere in the chain: every request is a legitimately formatted, protocol-valid event submitted to an endpoint explicitly designed to accept unauthenticated writes. Distinct from AVE-2026-00044 (Async Task Result Poisoning): that record's own stated distinguishing property, explicitly named in its description, is a temporal gap between task dispatch and a later, separate turn's result consumption, which is what it identifies as bypassing synchronous safety checks. This record's mechanism is a synchronous MCP tool call and response within a single interaction, a developer asks the agent to investigate an error and the poisoned response returns immediately, with no temporal gap, no task dispatch, and no later-turn consumption pattern anywhere in the mechanism. Distinct from AVE-2026-00043 (MCP App UI Payload Injection): that record's mechanism is instructions hidden in non-rendered elements, hidden divs, alt attributes, SVG metadata, invisible to the user while still processed by the model. This record's malicious content is fully rendered and visible, exactly as the legitimate system's own output would be; its evasion technique is visual mimicry of an authentic template, the structurally opposite concealment strategy from hiding content the user cannot see. Distinct from AVE-2026-00042 (REPL Code Mode Payload Injection): that record's mechanism is tool-result content containing escape sequences or string terminators that break out of a data context directly into a dynamically constructed eval() or exec() code string, a syntactic code-injection technique. This record requires no code-context breakout of any kind; the agent reads the content as natural-language diagnostic guidance within its own normal reasoning process and is persuaded to act on it, not tricked via a parsing or escaping vulnerability. Distinct from AVE-2026-00018 (Tool Result Manipulation): that record's mechanism is the agent itself being instructed by some other component to falsify, alter, or suppress a tool result before reporting it to a user or downstream system.

scored at maximum (1): the entire technique is centered on visually mimicking the integration's own authentic, system-generated template so precisely that no formatting or structural cue distinguishes the compromise, genuine template-identity mimicry rather than a missing re-validation step on an honest, unchanged identity. natural_language_input scored at maximum (1): unlike the structural, syntactic mechanisms in AVE-2026-00084 and AVE-2026-00086 from the same sourcing pass, this mechanism's entire exploitation step is the agent reading natural-language, markdown-formatted content and being persuaded, as a reasoning act, that it represents legitimate guidance, a natural-language-input mechanism in the most direct sense. data_access and external_dependencies scored at maximum (1): demonstrated impact is arbitrary command execution with full developer privileges, and the mechanism is specific to integrations whose own ingest architecture accepts unauthenticated or

precondition requiring the attacker to obtain the target's own ingest credential (AT:P, though the source's own finding that 2,388 organizations have publicly exposed credentials means this precondition is often trivially satisfied in practice), no additional privilege or unusual user interaction beyond the agent's own normal diagnostic workflow (PR:N/UI:N), full confidentiality/integrity impact given arbitrary command execution (VC:H/VI:H, SC:H/SI:H), and low availability impact at either layer (VA:L/SA:L) since this is not primarily a denial-of-service-shaped class. thm set to 1 (mechanism real and demonstrated): a real, disclosed, reproduced attack against a specific, named, widely-deployed production integration, with a measured 85% success rate across three current production coding agents and a real, acknowledged response from the affected vendor, not a theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): the affected vendor's own response was a narrow, single-payload-string content filter rather than a structural fix, and the vendor itself states the underlying

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "read_date": "2026-09-05" + }, + "nist_ai_rmf": { + "pin_status": "unknown", + "read_date": "2026-10-15" + } + } + }, + { + "ave_id": "AVE-2026-00081", + "schema_version": "1.2.0", + "status": "active", + "title": "Lingering authority: a task-scoped capability outlives the episode that justified it", + "attack_class": "Persistence - Lingering Authority", + "severity": "MEDIUM", + "description": "An agent is granted a temporary resource or effect capability -- a tool permission, credential, or access token -- scoped to a specific task, subgoal, or episode.

This record involves no bypass of any check -- the grant was legitimately issued and nothing re-checks it when its own justifying condition ends. Distinct from AVE-2026-00045 (Cross-App-Access Escalation): that record's grant is legitimately used, unexpired, for a purpose outside its scope, within a single session with no elapsed time or external event required.

MCP07 (Insufficient Authentication & Authorization) was also checked and rejected: its own text is about authentication/identity verification and cross-agent token reuse, not episode-closure-triggered revocation specifically. owasp_asi mapped to ASI03 (Identity and Privilege Abuse) after reading the actual 2026 PDF directly (genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026, pages 15-16): Common Example of the Vulnerability #4 is literally 'Time-of-Check to Time-of-Use (TOCTOU) in Agent Workflows...

An agent's skill router typically discovers skills across several local roots of differing trust (e.g. a user-level directory the operator controls directly, and a workspace-level directory any collaborator with repository write access can also write to), then flattens all discovered skills into one name-keyed lookup with no per-root namespace separation. When two skills collide on the same resolved name, whichever the router resolves last silently shadows the other, with no content-level warning, conflict indicator, or operator-visible signal that a collision occurred at all.

MCP09 (Shadow MCP Servers) was considered and rejected after reading its real text: that category describes unregistered/ungoverned server deployments as an infrastructure-visibility problem, not a client-side skill-namespace collision -- a worse fit than MCP03 despite 'shadow' resonating with 'shadowing' at the label level, exactly the kind of same-word-different-mechanism trap OWASP/www-project-mcp-top-10#52 already documents elsewhere in this corpus. No category in the current 2025/ Top 10 cleanly describes a local name-collision-driven silent substitution; flagging this as a real gap worth raising with that project rather than forcing a second stretch tag. owasp_asi left empty after checking all ten categories' real primary-source text directly (genai.owasp.org, 'OWASP Top 10 for Agentic Applications 2026', download/52117): ASI03 (Identity and Privilege Abuse) was the closest candidate but its real mechanism is agent-to-agent delegation-chain and credential-cache exploitation, not a local file-resolution collision with no identity claim involved; ASI02, ASI06, ASI09, and ASI10 were also read directly and ruled out on the same basis. nist_ai_rmf left empty rather than copying this corpus's own dominant (MAP-1.5, MEASURE-2.5, MANAGE-1.3) pattern, which appears on 25 of roughly 56 tagged records: checked all three subcategories against the real NIST AI 100-1 text (Tables 2-4) directly, and all three are generic organizational-process subcategories (documented risk tolerance, model validity/reliability testing, documented risk-response planning) that don't describe this record's specific mechanism any more than they'd describe nearly any other AI risk finding -- a strong signal this corpus-wide pattern is unverified boilerplate rather than a genuine per-record mapping, worth a dedicated nist_ai_rmf audit mirroring the earlier owasp_asi audit (issue #196), not something this one record's drafting should silently perpetuate." + }, + "evidence_kind_default": "config_schema", + "detection_stage": "static_detection", + "detection_layer": "registry_metadata", + "confidence_baseline": 0.9, + "evidence_vantage": "artifact", + "evidence_basis_engines": [ + "pattern" + ], + "derivable_into": [ + "rug-pull-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/tree/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025", + "read_date": "2026-09-09" + }, + "mitre_atlas": { + "version": "5.6.0", + "commit": "41d4f5ca4112f0e492ffaa3ebff07dc80a75afa5", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/41d4f5ca4112f0e492ffaa3ebff07dc80a75afa5/dist/ATLAS.yaml", + "read_date": "2026-09-09" + } + } + }, + { + "ave_id": "AVE-2026-00083", + "schema_version": "1.2.0", + "status": "active", + "title": "Silent guardrail comparison failure: a protection mechanism that executes but never evaluates its verdict", + "attack_class": "Trust Boundary - Silent Guardrail Comparison Failure", + "severity": "MEDIUM", + "description": "A protection mechanism -- a guardrail, an approval gate, a judge or eval scorer, a policy check -- is present in a component's own code (or in the agent framework, SDK, or proxy library implementing it), is invoked on every request that reaches it, and its logs, code coverage, and test suite all show it executing normally. Despite this, the mechanism's own comparison, branch, or aggregation logic never genuinely evaluates the real input against its intended deny condition, so it returns the result read downstream as 'permitted' or 'no violation' regardless of, or for a wide class of, the actual input. Five structural forms produce this behavior, each independently reproduced against shipped, real-world code by arian-gogani (github.com/arian-gogani/failopen): (1) an elif intended to catch a global or catch-all verdict is bound to the wrong enclosing conditional, making it unreachable once an unrelated, narrower branch is taken; (2) a verdict or classification value is declared as a bare, loosely-typed string -- often arriving from a model completion, json.loads, or a subprocess -- and compared with an exact == against a single expected literal, so any other phrasing (a full sentence, different casing, a synonym, an empty string) falls through to the permissive branch, reproduced in deepeval's role-violation, prompt-alignment, and conversation-completeness metrics scoring a judge verdict of 'Yes, the model violated its assigned role' as full compliance (confident-ai/deepeval#3283), litellm's Aporia guardrail hook forwarding content marked 'modify' or 'rephrase' unmodified because only the literal 'block' is handled (BerriAI/litellm#41097), and a microsoft/autogen governance sample executing on any verdict string it does not recognize as 'deny' (microsoft/autogen#7960); (3) the same approval or validation helper is invoked from two or more call sites with opposite defaults for identical, malformed input -- raising on one path, silently returning a permissive default on the other -- reproduced in openai-agents-python's needs_approval evaluator diverging between its core runner (raises UserError) and its realtime session (returns False, read as approval granted) for the same unrecognized configuration value (openai/openai-agents-python#5024), and guardrails-ai's on_fail default diverging between its Python API (raises) and its RAIL config path (silently becomes a no-op) for the same validator (guardrails-ai/guardrails#1656); (4) an error-handling or absent-dependency path omits, or an unparseable value silently coerces into, the specific state the downstream verdict logic reads, so an errored or unreachable check counts as passing -- reproduced in AutoGPT classic's Agent Protocol server path constructing an agent with no permission_manager (the CLI entry point in the same codebase always supplies one), so Agent.execute()'s own 'if self.permission_manager:' guard silently skips the entire deny-list check only on the network-facing path, and in protectai/rebuff's LLM detection tactic, where an unparseable model completion parses to NaN and 'NaN > threshold' is always false; and (5) a security verdict is computed with all() or any() over a collection that a reachable configuration or caller-supplied path can leave empty, so the aggregate reports a full pass having evaluated zero checks -- all([]) is True by definition, with a live, confirmed instance in a guardrail-orchestration product's own verdict aggregation currently under coordinated disclosure and deliberately unnamed by the source pending vendor response. The same measurement found zero instances of one detectable shape of this defect across 1,128,865 lines of mature, heavily reviewed Python (certbot, bandit, pyjwt, sigstore-python, python-tuf, detect-secrets) and fifteen confirmed instances across thirty-six projects whose enforcement code is roughly eighteen months old or newer (twenty-one read and found clean), indicating this concentrates in newly-written enforcement layers rather than software broadly. The common, externally observable behavior across all five forms -- and the reason this is drafted as one behavioral class rather than five separate ones -- is that the mechanism's own telemetry is indistinguishable from a genuine pass: the check appears in logs and traces, the deciding line is marked covered because it executes, and a project's own test suite can stay green with the defect present, because tests are typically written from the same understanding of the input space as the code being tested. Distinct from AVE-2026-00063 (Approval Gate Bypassed via Declarative Configuration): that record's mechanism is a config flag that visibly and legibly disables a check, discoverable by a reviewer reading the config file itself. This record's check is never disabled or bypassed; it is invoked and executes, and is unreachable, mistyped, divergent, or blind to real state at the code level -- invisible to a config or instruction-text review and requiring source-level or behavioral analysis to surface. Distinct from AVE-2026-00076 (Natural-Language Steering of an Approval Classifier Subagent): that record's classifier genuinely evaluates its real input and is merely biased toward a looser decision by adversarial natural-language steering text reaching it. This record's mechanism produces the permissive result independent of any steering content at all -- the comparison itself is structurally incapable of reaching its deny branch, or is blind to the real input, regardless of what that input says. Distinct from AVE-2026-00078 (Unverified Multi-Agent Consensus) and AVE-2026-00079 (Plan-to-Execution Binding Bypass): both describe an orchestrator's own total absence of a verification step (no quorum check exists; no plan-to-trace binding exists anywhere in the architecture). This record's mechanism is the inverse -- a verification step does exist, is invoked, and is intended to run, but its own internal logic never reaches or genuinely evaluates the comparison that would make it work. Distinct from AVE-2026-00038 (Unbounded Tool Use or Sub-Agent Spawning): that record is a component instructing an agent to ignore scope boundaries entirely, with no gating mechanism present in the architecture at all. This record requires a real gating mechanism to be present, configured, and invoked, whose own internal comparison then fails silently.

non_determinism because forms 1/3/4/5 are deterministic control-flow or aggregation defects that fire identically every run, while form 2's failure rate depends on how an LLM judge happens to phrase its verdict on a given call; natural_language_input because form 2 is centrally about natural-language verdict phrasing defeating an exact-match comparison, while forms 1/3/4/5 are pure structural/syntactic defects (an elif's scope, a divergent default, an emptied collection) that would occur identically for a boolean or enum verdict; data_access because the actual reach of a defeated guardrail varies by which action it was gating, from an eval score (low) to unrestricted shell execution (AutoGPT, high). multi_agent, self_modification, and dynamic_identity scored 0: the mechanism is single-component, does not require the component to alter its own instructions, and involves no impersonation or identity claim of any kind. persistent_memory scored 0: the underlying code defect is a static, load-bearing property of the shipped software rather than an effect that persists in the agent's own session or memory store, and a single bypass event does not itself write a lasting belief or credential into agent state the way AVE-2026-00019 or AVE-2026-00081 describe. thm set to 1 (mechanism real and demonstrated): all five forms are reproduced with an executable, one-command script against the actual shipped package or sample (not a retyped approximation) across seven independent, unrelated codebases, plus a published static detector with measured real-world yield -- this is a working exploit description across multiple, independently-confirmed targets, not a single theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): unlike a known fix such as re-enabling TLS verification or pinning a dependency, there is currently no standard, widely-adopted practice for this defect class -- the primary source's own stated goal is establishing an identifier and vocabulary precisely because none exists yet, and the source's own detector implements only one of five forms. cvss_base_vector reflects a network-reachable check (AV:N) requiring no special attacker positioning, privilege, or user interaction (AT:N/PR:N/UI:N) to encounter, full confidentiality/integrity compromise at the mechanism's own decision boundary and at whatever it gates (VC:H/VI:H, SC:H/SI:H) since the defect grants exactly the access or action the guardrail existed to withhold, and no availability impact at either layer (VA:N/SA:N) since this is not a denial-of-service-shaped class. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states the category covers cases where 'MCP servers, tools, or agents fail to properly verify identities or enforce access controls during interactions' and where 'authorization flaws occur when... Agents or users can perform actions beyond their intended privileges' -- the consequence this record produces exactly. Flagged honestly as an imperfect fit: MCP07's own worked checklist (hard-coded secrets, client-side-only enforcement, unverified caller-identity metadata, missing scope validation) is entirely about identity/token-based authorization being absent or weak, not about a present, invoked authorization check whose own comparison logic is structurally defective -- the closer framing is CWE-693/Protection Mechanism Failure at the code-weakness level, which OWASP's MCP Top 10 has no direct analogue of. MCP03 (Tool Poisoning), MCP06 (Intent Flow Subversion), MCP08 (Lack of Audit and Telemetry), and MCP09 (Shadow MCP Servers) were also read in full and rejected: MCP03 and MCP06 require a compromised or adversarial tool description/context altering agent behavior, which this record's mechanism does not need (four of five forms fire on entirely benign input); MCP08 is the near-opposite of this record's mechanism, since the defective check still produces normal-looking logs and telemetry rather than an absence of them; MCP09 concerns unregistered server deployments, an infrastructure-governance problem unrelated to a code-level comparison defect. owasp_asi confirmed empty after reading the full primary-source PDF directly (genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026, 'OWASP Top 10 for Agentic Applications 2026', December 2025, all ten ASI01-ASI10 category descriptions read in full, not just titles): ASI03 (Identity and Privilege Abuse)'s own TOCTOU example concerns permissions validated once at workflow start and never re-checked as they change, a lifecycle/timing gap distinct from a same-request comparison that never evaluates at all; ASI02 (Tool Misuse and Exploitation) requires an agent applying an otherwise-legitimate tool unsafely, not a defect in the enforcement code itself; ASI09 (Human-Agent Trust Exploitation) is specifically about human over-reliance on an agent's own persuasive output, not a code-level guardrail defect with no human judgment involved. No category cleanly describes a present, invoked protection mechanism whose own comparison is structurally incapable of reaching its deny branch; a genuine gap, matching the primary source's own independent finding that this is also absent from CSA's named March 2026 gap list. mitre_atlas confirmed empty after fetching and searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly for guardrail/verdict/bypass/evasion/defense-evasion language: AML.T0054 (LLM Jailbreak) requires adversarial prompting to induce a model to override its own guardrails, a fundamentally different mechanism from a code-level comparison defect that fires independent of any adversarial input; AML.T0107 (Exploitation for Defense Evasion) was the closest candidate, and its second sentence ('vulnerabilities may exist in defensive security software that can be used to disable or circumvent them') is a real textual echo, but the technique's controlling definition requires 'a programming error... to execute adversary-controlled code', which is not required by four of this record's five forms (no code execution or active exploitation is needed; the defect misfires on ordinary, even benign, requests) -- a real gap rather than a stretch worth forcing. nist_ai_rmf confirmed empty after reading the actual NIST AI 100-1 text (Tables 1-4) directly: MEASURE 1.2 ('effectiveness of existing controls are regularly assessed and updated') was the closest candidate, but per this project's own prior audit (issue #196) this is exactly the kind of generic organizational-process subcategory that could describe nearly any AI risk finding and was flagged as likely unverified boilerplate elsewhere in this corpus -- not a mapping specific to this record's mechanism, so left empty with this note rather than perpetuated." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.45, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP07-2025%E2%80%93Insufficient-Authentication%26Authorization.md", + "read_date": "2026-09-21" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00088", + "schema_version": "1.2.0", + "status": "active", + "component_type": "agent", + "title": "Sandbox side-effect trust handoff: an agent-written workspace file is run by a trusted component outside the sandbox", + "attack_class": "Sandbox Escape - Side-Effect Trust Handoff", + "severity": "MEDIUM", + "description": "A coding agent runs inside a sandbox that lets it create and modify files in the workspace but not run arbitrary commands on the host. Content the agent processes (a README, a project note, a dependency's documentation) steers it into writing a file the sandbox allows: a hook definition, an editor task, Git metadata, the agent tool's own project configuration, or an interpreter inside a virtualenv. A more-privileged component outside the sandbox later reads that file and executes it as trusted configuration or code: the agent harness's own hook engine or startup configuration loader, the editor's task runner, or an editor extension that runs Git or discovers Python interpreters. That component does not distinguish agent-written files from user-authored ones and does not run what it consumes under the sandbox's execution policy, so the agent's side effect executes on the host with the user's privileges even though the agent process itself never left the sandbox. Demonstrated across vendors: Cursor ran a Stop hook from an agent-written .claude/settings.local.json at the end of the turn (CVE-2026-48124), ran Git hooks the agent planted in improperly protected .git settings (CVE-2026-26268), ran a core.fsmonitor helper the agent placed in a repository created with --separate-git-dir past a literal .git/config deny rule (patched in 3.0.0), and ran a virtualenv interpreter the agent replaced when the Python extension invoked it outside the sandbox (CVE-2026-73217). Claude Code loaded SessionStart hooks from a .claude/settings.json the sandbox let the agent create because the file was absent at startup (CVE-2026-25725). Antigravity's write tools let the agent drop a runOn: folderOpen task into .vscode/tasks.json, which VS Code's task runner executed on the host on the next open. Codex CLI let apply_patch create .codex/config.toml, whose notify command runs outside the sandbox, and Gemini CLI mounted the user's settings.json writable into its container.

The overlap is real for one vector of CVE-2026-48124, whose advisory names both 'a malicious workspace' and 'an agent-created file'; it is cited here for the agent-written PoC Pillar published. Also compared field by field with AVE-2026-00054 (runtime: the sandbox itself is broken by a prototype-chain payload; here the sandbox works as designed), AVE-2026-00050 (runtime: hook registration beyond a component manifest at session init; no manifest is involved here), AVE-2026-00084 (registry_metadata: a vetted plugin's update rebinds a hook; here the change is the agent's own write), AVE-2026-00071 (registry_metadata: daemon redirect to remote infrastructure), AVE-2026-00075 (skill_file: bytecode diverging from reviewed source) and AVE-2026-00063 (an approval flag in config; overlaps only where an agent-written config also sets one, as in Cymulate's Codex approval_policy, and the executing step there is still notify run outside the sandbox). entry_class model_generated reused rather than forked: as in AVE-2026-00056, the payload is something the agent itself produces (a file it writes), not something it reads. Q6 (replace the LLM with a deterministic program with the same workspace write access): the flaw partly survives, since any sandboxed process whose output a privileged consumer trusts can escape the same way. What remains agentic: the sandbox exists to contain a model steered by untrusted content, and the attacker needs only text the model reads rather than code execution inside the sandbox, because writing arbitrary workspace files is the agent's normal capability; the decision to write comes from model reasoning over injected content (the CVE-2026-26268 advisory's own words: 'A malicious agent (ie prompt injection)'); and in most instances the trusted consumer is the agent harness itself (hooks, notify, startup config) treating its own agent's writes as the user's configuration. Classified A rather than E for that reason, with the partial survival stated. autonomy scored 1: once the file is written, the trusted component executes it on its own trigger with no further attacker interaction and no approval prompt. tool_use scored 1: the mechanism is the agent's own file-write or shell tool producing the artifact. non_determinism scored 0.5: exploitation depends on the model following injected content, which varies run to run (OpenAI's own closure of Cymulate's Codex report cited prompt injection). self_modification scored 0.5: in the hook, notify and settings instances the agent writes its own harness's configuration and so changes the agent runtime's later behavior; the Git, editor-task and virtualenv instances change a different component, so not 1. dynamic_identity scored 0.5: the consumer extends user-authored trust to an agent-written file, a trust-anchor confusion over authorship, scored as AVE-2026-00084 scored inherited vetting trust. persistent_memory scored 1: the written file stays on disk and re-executes on every later trigger (the CVE-2026-25725 advisory calls them 'persistent hooks'; Cymulate's Gemini settings persist across directories). natural_language_input scored 0: the delivery is natural language, but the exploit step at the boundary is structural (a configuration file executed by a component), which the scoring reference scores 0. data_access scored 1: execution runs as the user on the host, with the user's keys, tokens and files. external_dependencies scored 1: severity depends entirely on which host-side consumer trusts which file (a hook engine, a task runner, a Python or Git extension). multi_agent scored 0. cvss_base_vector follows the CVE-2026-25725 advisory's own vector: network-borne delivery through content the agent reads (AV:N), low complexity (AC:L), a precondition on sandbox or auto-run mode and on the agent following the content (AT:P), no privileges (PR:N), passive user interaction such as continuing the session or restarting the tool (UI:P), and full host impact (VC:H/VI:H/VA:H). The Cursor advisory scored its instance higher (8.5, AV:L/AT:N) and CVE-2026-26268 was scored 8.0 under CVSS 3.1; 7.7 is the most conservative vendor reading of the same handoff. thm set to 0.90 (PoC exists, not exploited in the wild): every instance cited has a working PoC and most have a vendor-confirmed fix, but no in-the-wild exploitation is reported. mitigation_factor set to 1: fixes are per path and per product (Antigravity's blocklist missed tasks.json, Cursor's rule missed .git-alt), Google downgraded one instance, OpenAI closed another as informational and Gemini CLI's was unresolved at disclosure; no ecosystem-wide standard mitigation exists. MEDIUM despite host code execution, honestly, as with AVE-2026-00064: a narrow handoff mechanism with no multi-agent component. owasp_mcp mapped to MCP05 (Command Injection & Execution) after reading the category text at commit 165fe0f78ef104459237b4a8e0f6e78db9b02391: its description covers instructions hidden in context causing the agent to generate malicious commands, and its checklist names 'No runtime sandboxing isolates tool execution from the host system' and 'Execution occurs across different contexts (e.g., generating commands on one server that execute on another without re-validation)'. MCP02 was read and rejected (it is permission scope drifting over time). owasp_asi mapped to ASI05 (Unexpected Code Execution) after reading the 2026 document: it covers execution 'that leads to host or container compromise, persistence, or sandbox escape', and its Example 4 is an agent-generated object passed to another component and executed without validation; the ASI02 text routes code-execution outcomes to ASI05, and ASI03 (identity and delegation abuse) was read and rejected. mitre_atlas mapped to AML.T0105 (Escape to Host) and AML.T0081 (Modify AI Agent Configuration) after reading both in the live ATLAS.yaml (v5.6.0): T0105's own text names 'modifying an AI Agent's configuration to disable safety features or user confirmations could allow the adversary to invoke tools to be run on host environments rather than in the sandbox'; T0081 covers the subset where the written file is the agent harness's own configuration (Claude Code and Cursor hook settings, Codex config.toml, Gemini settings.json), not the Git, editor-task or virtualenv instances.

The harness, however, computes that scope from a value the model supplies in the tool call itself, such as the command's working directory, rather than from the session's own root. Content the model reads (an MCP tool response, a web search result, a README) steers it to set that value to a location outside the workspace, and the sandbox grants write access there. The agent can then write the sandbox's own helper binary, the user's shell startup files or launch agents without approval, so later commands run unsandboxed. The model does not break the boundary; it sets it. Demonstrated in two products. Codex CLI 0.2.0 to 0.38.0 could treat a model-generated cwd as the sandbox's writable root, including paths outside the folder where the user started the session (CVE-2025-59532); the fix separates the command's working directory from the directory the sandbox policy is computed from. Cursor before 3.0 added the run_terminal_cmd tool's optional working_directory parameter to the sandbox's allowed write list whenever the model set a non-default value (CVE-2026-50548, part of Cato AI Labs' DuneSlide research), and the proof of concept overwrote Cursor's cursorsandbox helper.

Related but kept out of the fingerprint: CVE-2026-50549 (Cursor falls back to the in-workspace symlink path when canonicalization fails and writes without approval) and CVE-2026-34452 (the Anthropic Python SDK's async memory tool validated a model-supplied path, then used the unresolved path, a validate-then-use race exploitable by a local attacker able to write to the memory directory).

Q6 (replace the LLM with a deterministic program): the flaw, in the form that matters, does not survive. A conventional program does not take its sandbox boundary from the output of the component the sandbox exists to contain; Cato AI Labs' own write-up: 'Traditionally, a remote attacker cannot control the working directory of a sandboxed operation.' Strongest counterargument: this is an ordinary input-validation bug (the Advisory Database files CVE-2025-59532 as CWE-20), and a deterministic sandbox that derived its root from an untrusted request would have the same flaw. Answer: the structural error can exist without a model, but the input only becomes attacker-reachable because a model generates it, so the constrained party, a model steerable by any content it reads, is the party choosing the boundary; both vendor fixes confirm the framing by separating model-supplied execution parameters from user-established policy (Codex's fix commit splits command_cwd from sandbox_policy_cwd). Classified A rather than E. autonomy scored 1: once the model sets the parameter, the sandbox grants the scope and writes proceed with no approval in auto-run mode. tool_use scored 1: the mechanism is a tool-call parameter. non_determinism scored 0.5: exploitation depends on the model following injected content (Cursor initially rejected the report on threat-model grounds about MCP misuse, not reproducibility, but model compliance still varies). self_modification scored 0.5: the demonstrated chain overwrites the agent's own sandbox helper so later commands run unsandboxed, a change to the agent runtime, though the class itself is the widened scope, not the helper overwrite. dynamic_identity scored 0.5: the policy layer gives a model-supplied value the authority of the user-established session root, a trust-anchor confusion over who sets policy, scored as AVE-2026-00088 and AVE-2026-00084 scored theirs. persistent_memory scored 0.5: the escape happens within a session, but its demonstrated payloads persist (an overwritten sandbox helper, ~/.zshrc, ~/Library/LaunchAgents). natural_language_input scored 0: the delivery is natural language but the boundary step is a structured parameter value, which the scoring reference scores 0. data_access scored 1: arbitrary writes anywhere the process can write, leading to host command execution. external_dependencies scored 1: severity depends entirely on whether a specific harness derives its policy from the parameter (Codex CLI before 0.39.0, Cursor before 3.0). multi_agent scored 0. cvss_base_vector is the Codex advisory's own vector for CVE-2025-59532, the most conservative vendor reading (Cato scores both DuneSlide findings CVSS 9.8 under 3.1, Cursor rates CVE-2026-50548 Critical): network-borne injected content (AV:N), low complexity (AC:L), no attack-time precondition beyond the default auto-run sandbox (AT:N), low privileges as the vendor scored it (PR:L), passive user interaction (an innocuous prompt, UI:P), full impact (VC:H/VI:H/VA:H). thm set to 0.90 (PoC exists, not exploited in the wild): both instances have working PoCs and vendor fixes, with no reported in-the-wild exploitation. mitigation_factor set to 1: the fixes are per product, Cursor first rejected the report as outside its threat model, and Cato states it is disclosing further issues in other coding agents; no ecosystem-wide standard mitigation exists. owasp_mcp mapped to MCP05 (Command Injection & Execution) after reading the category text at commit 165fe0f78ef104459237b4a8e0f6e78db9b02391: its checklist names 'Agent outputs are not constrained to allowlists of permitted commands, arguments, or file paths' and 'No runtime sandboxing isolates tool execution from the host system'.

A record that leaves `active` stays in the published files with +its full content. Treat any status other than `active` as not active, and do +not assume the list of statuses is complete.

A plugin passes marketplace or registry vetting under a benign, reviewed lifecycle-hook configuration and a stable public identity. A later version update, published under that same identity, silently adds or rebinds a hook to an attacker-chosen command. The harness's own automatic update-sync path applies the new binding with no per-entry re-authorization, no new LLM decision, and typically no user-facing notification distinguishing the change from the plugin's original, already-reviewed state -- the update inherits the trust the original install earned. When the bound event next fires, the harness dispatches the attacker's command directly from its own event-dispatch layer, outside the model's reasoning or tool-call decision path entirely, so prompt-level, alignment, or model-mediated defenses never see the exploitation step and cannot intervene. Confirmed concretely on Claude Code: the harness's automatic marketplace-update synchronization checks repositories for manifest changes and applies them, hook entries included, without validating individual hook entries against what a reviewer or scanner last inspected. Demonstrated with HookPry, an open-source, fully automated attack framework realizing this mechanism across seven real agent harnesses (Claude Code, OpenClaw, OpenHarness, Codex CLI, OpenCode, Hermes, WorkBuddy) and five LLM backends, 25 harness/backend combinations, 1,000 end-to-end runs: HookPry compromises all seven harnesses, with a 77.0% micro-averaged and 77.9% macro-averaged end-to-end attack success rate, peaking at 92.5% on the Hermes harness, and 83.9% average mechanism utility (the proportion of runs in which hook triggering, payload loading, and hook registration actually occur, independent of whether the full external effect is confirmed). An ablation study confirms the temporal-decoupling component is load-bearing, not incidental: blocking the ability for a new hook entry to inherit an existing plugin identity's authorization drops end-to-end success to 0%, and removing the harness-specific compilation step (translating the attack into each harness's native lifecycle-hook interface) also drops it to 0%, while removing only the metadata-optimization component (which improves marketplace discoverability of the carrier plugin, not the exploitation mechanism itself) reduces but does not eliminate success (a 16.4 percentage-point drop). Representative defenses are shown insufficient against the confirmed mechanism: Microsoft Defender achieves 0% recall, and the union of three static defenses still misses 47.5% of the malicious artifacts HookPry generates. The paper's authors state they have responsibly disclosed their findings to all affected harness vendors and are awaiting response. Distinct from AVE-2026-00046 (Tool Hook Interception): that record's mechanism is a skill's own declared instruction text asking the agent to register a hook targeting tool calls -- an LLM-mediated act, visible in the skill's stated instructions and requiring the model to act on them. This record's hook binding is applied by the harness's own update-sync path with no LLM decision, instruction-following, or content read by the model involved at any point. Distinct from AVE-2026-00050 (Parasitic Toolchain): that record is an undeclared registration exceeding a component's own manifest scope, occurring at session initialization. This record's plugin legitimately has lifecycle-hook capability declared in its manifest from the start; the violation is that a later, same-identity update can silently change which event and command are bound, with the harness treating that change as covered by the original install's already-completed vetting. Distinct from AVE-2026-00062 (Unpinned Dependency Substitution): that record's mechanism requires a mutable version specifier (a floating tag or unbounded range) causing a different version to resolve than intended. This record's mechanism works even against a correctly pinned, explicitly versioned update that a marketplace's own update mechanism legitimately and deliberately applies -- the gap is the absence of per-update hook re-authorization, not dependency-resolution ambiguity. Distinct from AVE-2026-00081 (Lingering Authority): that record is a task or episode-scoped capability grant reused after its own closure event, within a single session's lifecycle.

"HIGH", + "spec_version": "0.8", + "notes": "autonomy scored at maximum (1): once the malicious update is published and accepted by the harness's own update-sync path, the hook fires on the next matching lifecycle event with zero further attacker interaction. tool_use scored 0, deliberately, not by oversight: the paper's own central finding is that hook dispatch happens outside the LLM's tool-calling and reasoning path entirely -- the harness's own event-dispatch layer spawns the subprocess directly, so this mechanism does not require, and specifically bypasses, the agent's own tool-calling capability. persistent_memory and data_access scored at maximum (1): the hook binding, once updated, persists across every future session until removed or patched (a standing config-state change, not a one-off), and the confirmed effect range spans credential collection, data exfiltration, resource hijacking, command and control, tampering, and privilege escalation -- the ten attack objectives HookPry's own taxonomy formalizes against MITRE ATT&CK tactics. external_dependencies scored at maximum (1): the paper's own cross-harness evaluation shows real, measured effectiveness variance by harness (55.3% to 93.4% macro-average by attack category, 41.7% to 92.5% by harness), and a harness whose update-sync path already re-validates hook entries per update would not be vulnerable at all -- severity is definitionally tied to which specific harness is in use. non_determinism and dynamic_identity scored 0.5: the paper's own RQ1.2 measures real, nonzero cross-backend standard deviation in end-to-end success (1.1 to 9.6 percentage points depending on harness) tied to which LLM backend generates the triggering tool-use pattern, and the mechanism exploits the harness's own assumption that a stable, genuine, unchanged plugin identity across a version update still carries its original trust level -- real trust-anchor confusion, but not a spoofed or false identity claim, since the identity genuinely is the same plugin throughout. multi_agent, self_modification, and natural_language_input scored 0: the mechanism is single-harness, does not require the component to alter its own instructions, and involves no natural-language content at any point in the exploitation path -- the payload is a shell command bound via manifest configuration, not text a model interprets. cvss_base_vector reflects a network-delivered update (AV:N), low complexity once the update channel is controlled (AC:L), a real attacker-controlled-update precondition (AT:P, matching the paper's own supply-chain threat model: the attacker controls only plugin metadata and lifecycle-hook configuration, not local or repository access), no privileges or user interaction required beyond that precondition (PR:N/UI:N), full confidentiality/integrity impact at both the vulnerable harness and the subsequent host system (VC:H/VI:H, SC:H/SI:H) given arbitrary command execution with host privileges, and low rather than high availability impact at either layer (VA:L/SA:L) since this is not primarily a denial-of-service-shaped class even though resource-hijacking effects were among the ten confirmed attack objectives. thm set to 1 (mechanism real and demonstrated): 1,000 real end-to-end runs across seven real, named, current agent harnesses and five real LLM backends, with an ablation study isolating which components are load-bearing and a stated responsible disclosure already sent to affected vendors -- this is a working, reproduced exploit framework, not a theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): the paper's own evaluation shows representative production defenses, including a major commercial antivirus product, are insufficient against the confirmed mechanism, and no standard practice for per-update lifecycle-hook re-authorization is yet in place across the evaluated harnesses. owasp_mcp mapped to MCP04 (Software Supply Chain Attacks & Dependency Tampering) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP04 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states 'compromised dependencies can alter agent behavior, introduce hidden backdoors, or modify protocol semantics without triggering detection,' and its vulnerability checklist names 'fetch dependencies automatically during runtime/build' and 'no integrity verification mechanisms' verbatim -- both a direct match for a harness's own automatic update-sync path applying an unvalidated hook-binding change. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly (genai.owasp.org, 'OWASP Top 10 for Agentic Applications 2026', pages 18-20): its own description states these vulnerabilities 'arise when agents, tools, and related artefacts they work with are provided by third parties and may be malicious, compromised, or tampered with in transit,' and that 'agentic ecosystems often compose capabilities at runtime -- loading external tools/agent personas dynamically -- thereby increasing the attack surface,' a direct categorical match even though none of ASI04's own worked examples describes this specific lifecycle-hook-update variant. mitre_atlas mapped to AML.T0010.005 (AI Agent Tool, under AML.T0010 AI Supply Chain Compromise) after searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly: its own description names agent tools as 'an attractive target for adversaries because compromising an AI agent can provide them with broad accesses and permissions on the victim's system via the agent's other tools' and cites a real prior incident (the Postmark MCP npm backdoor) of a trusted, published package being compromised via an update -- structurally analogous. Flagged honestly as an imperfect fit: T0010.005's own text centers on tools carrying malicious code or prompt injections, a content-level compromise, while this record's specific mechanism is narrower and does not require the plugin's own code or description to be malicious at all, only its lifecycle-hook manifest entry; no more specific existing ATLAS technique naming lifecycle-hook update-time trust decoupling was found. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text (Tables 1-4) directly: MAP 4.2 ('internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') was the closest candidate, but it is a generic third-party-component risk-documentation subcategory that does not describe this record's specific update-time trust-decoupling mechanism any more precisely than it would describe nearly any other third-party supply-chain finding -- left empty rather than perpetuated, matching the same discipline applied to AVE-2026-00081 and AVE-2026-00083." + }, + "evidence_kind_default": "config_schema", + "detection_stage": "static_detection", + "detection_layer": "registry_metadata", + "confidence_baseline": 0.7, + "evidence_basis_engines": [ + "pattern", + "sandbox" + ], + "derivable_into": [ + "remote-control-chain", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00085", + "schema_version": "1.3.0", + "status": "active", + "title": "Collusive cross-skill composition: a malicious workflow split across independently benign skills", + "attack_class": "Obfuscation - Collusive Cross-Skill Composition", + "severity": "HIGH", + "description": "An attacker decomposes a single malicious workflow into three or more sub-payloads and packages each as its own independently-installable skill, with a real, narrow, individually-benign function -- one might be a project-setup helper, another an API analyzer, another a test runner. Adjacent sub-skills are connected through genuine runtime artifacts, a file, an environment variable, a task-state value, that one sub-skill's actual execution produces and a subsequent sub-skill's execution consumes, so the complete harmful behavior exists only in the ordered composition's real data flow during genuine agent execution and never in any single skill's own declared instructions, code, or permissions. Because per-skill scanners inspect each skill's own content, permissions, dependencies, and code behavior in isolation, every sub-skill passes individual review, and the complete attack surfaces only when all sub-skills are installed together and the agent executes them in their intended order. Demonstrated with ColluSkill, evaluated against six real, currently-deployed skill scanners (CISCO Skill Scanner, SkillFortify, Auditor, SlowMist, Vetter, SkillSpector): an average 96.0% attack success rate across the six, reaching 100% on two of them, and the best performance among five single-skill and one multi-skill attack baseline evaluated on the same scanners (the next-best baseline, a multi-skill benchmark not purpose-built for scanner evasion, reaches 34.8%). ColluSkill's chain planning uses an attacker-controlled LLM to infer an ordered payload plan and iteratively rewrites any sub-skill a scanner flags, using the scanner's own feedback, while keeping already-passing sub-skills unchanged -- this refinement measurably raises average attack success rate from 64.9% before any refinement to 96.0% after seven iterations. Real runtime execution is confirmed, not merely scanner evasion in the abstract: ColluSkill attack chains successfully activate on three real coding agents (OpenCode, Claude Code, Codex) across different model backbones (GPT-5.5, DeepSeek-V4-Pro, GLM-5.2), with chain activation success ranging 58.5% to 92.5% depending on the agent. The paper's own proposed defense, ChainGuard, a context-aware scanner that evaluates a candidate skill together with the full set of skills already installed rather than in isolation, reduces but does not eliminate the attack (22.5% residual attack success rate) while passing 99.5% of benign workflows. Distinct from AVE-2026-00059 (Fragmented Cross-Description Reassembly): that record's fragments are tool-description text spread across multiple tools, reassembled inside the model's own inference at a separately planted trigger, before any tool call executes -- a pure inference-time text-combination mechanism. This record's fragments are real, separately-installed skill packages whose harmful composition is reconstructed only through actual runtime artifact passing during genuine, completed execution, not text combined in the model's context. Distinct from AVE-2026-00057 (Static Analysis Evasion): that record's evasion mechanism is encoding or obfuscation within one skill's own payload, defeating single-pass static pattern matching on that one file. No sub-skill in this record's mechanism contains any encoded, obfuscated, or otherwise suspicious content at all; each is genuinely, functionally benign on its own, and the evasion is achieved by the composition itself, not by hiding content within any single skill. Distinct from AVE-2026-00070 (Distributed Cross-Agent Backdoor Fragments): that record's fragments are encrypted, dormant primitives embedded in tool observations, persisting across multiple distinct agents' own memories and reassembled externally by the attacker after the collaborative run ends. This record's sub-skills are unencrypted, fully functional, and complete their entire harmful workflow live, within one agent's own session, with no external post-run reassembly step and no multi-agent memory persistence involved. Distinct from AVE-2026-00067 (Skill Composition Trust Transfer): that record's mechanism is a downstream skill accepting an upstream skill's claimed endorsement or validation result as sufficient authorization without independently reverifying it -- a misplaced-trust-in-a-claim mechanism. No skill in this record's mechanism makes or relies on any trust or endorsement claim about another skill at all; the sub-skills exchange functional data artifacts as ordinary parts of one attacker-planned workflow, with no vouching or authorization claim anywhere in the chain. Distinct from AVE-2026-00068 (CLI Command Composition): that record is shell-state composition of already-trusted commands within one session, with no installation-time security-scanning-evasion property in its mechanism at all.

Also proposes ChainGuard, a context-aware cross-skill scanner reducing but not eliminating the attack (22.5% residual ASR, 99.5% benign-workflow pass rate).", + "url": "https://arxiv.org/abs/2608.09732" + }, + { + "tag": "AVE issue #290", + "text": "ave_id AVE-2026-00085 confirmed via the id-confirmation issue, including the distinctness comparison against AVE-2026-00057, AVE-2026-00059, AVE-2026-00067, AVE-2026-00068, and AVE-2026-00070.", + "url": "https://github.com/aveproject/ave/issues/290" + } + ], + "aivss": { + "cvss_base": 8.7, + "aarf": { + "autonomy": 1, + "tool_use": 1, + "multi_agent": 0, + "non_determinism": 0.5, + "self_modification": 0, + "dynamic_identity": 0, + "persistent_memory": 0.5, + "natural_language_input": 0.5, + "data_access": 1, + "external_dependencies": 1 + }, + "aars": 5.5, + "thm": 1, + "mitigation_factor": 1, + "aivss_score": 7.1, + "aivss_severity": "HIGH", + "spec_version": "0.8", + "notes": "autonomy and tool_use scored at maximum (1): once all sub-skills are installed, the chain executes during ordinary agent operation with no further attacker interaction, and the mechanism is definitionally about the agent's own skill/tool-invocation capability chaining multiple installed capabilities together. data_access and external_dependencies scored at maximum (1): the demonstrated effect range spans sensitive-data discovery with external transmission through backdoor activation, and severity is directly tied to which specific scanners and which specific agent/model backbone are in use -- the paper's own measured per-scanner ASR ranges from 91.5% to 100%, and per-agent chain activation from 58.5% to 92.5%, real, substantial variance by external dependency. non_determinism and natural_language_input scored 0.5, not higher: chain activation success is measurably backbone-dependent (a real, nonzero spread across GPT-5.5/DeepSeek-V4-Pro/GLM-5.2), and constructing the attack itself is LLM-driven (chain planning and iterative scanner-feedback rewriting), but the exploitation step once sub-skills are installed is governed by real data-artifact flow rather than natural-language steering of the target agent at call time, so neither factor reaches its maximum. persistent_memory scored 0.5: the sub-skills remain installed as a standing capability after the attack completes, but the harmful workflow itself completes within one normal session's execution rather than depending on cross-session dormancy the way a fragment-persistence mechanism would. multi_agent, self_modification, and dynamic_identity scored 0: the mechanism is single-agent, does not involve the component altering its own instructions, and no sub-skill makes any false or claimed identity, each is honestly whatever its narrow, benign function actually is. cvss_base_vector mirrors AVE-2026-00084's reasoning: network-delivered skill packages (AV:N), low complexity once the specific multi-skill precondition is met (AC:L), a real attacker-controlled precondition requiring three or more specific skills to be installed together (AT:P), no additional privilege or user interaction beyond ordinary skill installation and use (PR:N/UI:N), full confidentiality/integrity impact at both the agent and downstream systems given the paper's own demonstrated effects (VC:H/VI:H, SC:H/SI:H), and low rather than high availability impact at either layer (VA:L/SA:L) since this is not primarily a denial-of-service-shaped class. thm set to 1 (mechanism real and demonstrated): evaluated against six real, currently-deployed, named skill scanners with measured, reproducible results, and real chain execution confirmed on three real coding agents across three model backbones, not a theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): even the paper's own purpose-built defense, ChainGuard, leaves a real 22.5% residual attack success rate, and no evaluated production scanner defends against the mechanism at all today. owasp_mcp mapped to MCP04 (Software Supply Chain Attacks & Dependency Tampering) after reading the category's full primary-source text directly (same commit as AVE-2026-00084's citation, 165fe0f78ef104459237b4a8e0f6e78db9b02391): flagged honestly as an imperfect fit -- MCP04's own checklist centers on compromised or tampered third-party components, while every sub-skill in this mechanism is genuinely, individually benign and uncompromised; the fit is at the level of third-party-component-composition risk broadly, the best available category among the ten, not a precise mechanism match. MCP03 (Tool Poisoning) was also read in full and rejected: its real text is specifically about schema or contract tampering causing benign operations to map to destructive ones, a different mechanism from composing multiple genuinely-unmodified, individually-correct skills. owasp_asi mapped to ASI04 (Agentic Supply Chain Vulnerabilities) after reading the full 2026 PDF text directly: its own description states these vulnerabilities arise when 'agents, tools, and related artefacts they work with are provided by third parties' and that 'agentic ecosystems often compose capabilities at runtime... thereby increasing the attack surface' -- the phrase 'compose capabilities at runtime' is a close match for this record's own mechanism, a stronger fit than the same category's application to AVE-2026-00084. mitre_atlas confirmed empty after searching the live ATLAS.yaml directly: AML.T0010.005 (AI Agent Tool) centers on tools carrying malicious code or prompt injections, the opposite of this mechanism's property that no individual component is malicious; AML.T0067 (LLM Trusted Output Components Manipulation) and AML.T0094 (Delay Execution of LLM Instructions) both describe single-prompt evasion techniques, not multi-component decomposition defeating per-component scanning. No existing technique names workflow decomposition across multiple independently-scanned components as its own mechanism; a genuine gap, left empty rather than stretched a second time in this same sourcing pass. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic third-party-component boilerplate already flagged as non-specific on AVE-2026-00081, AVE-2026-00083, and AVE-2026-00084 was found to fit this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "static_detection", + "detection_layer": "content", + "confidence_baseline": 0.5, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "credential-exfiltration", + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP04-2025%E2%80%93Software-Supply-Chain-Attacks%26Dependency-Tampering.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00086", + "schema_version": "1.3.0", + "status": "active", + "title": "Mid-session WebMCP tool hijacking: a live registry swap replaces an already-discovered tool under its own name", + "attack_class": "Trust Boundary - Mid-Session Tool Registry Hijacking", + "severity": "HIGH", + "description": "WebMCP lets a website expose tools directly to an AI agent within a live browser session, so the set of tools an agent can observe and invoke is dynamic rather than fixed at session start. A compromised or malicious third-party script running on the same page, a CDN, an advertising SDK, or any other same-page JavaScript component, manipulates the agent's live tool registry during the session. In the AbortSignal-hijack form, the malicious script waits until a predefined trigger condition is satisfied, then uses the browser's AbortSignal API to unregister an already-discovered, already-invoked-at-least-once tool, and immediately re-registers a malicious replacement under the exact same tool name before the agent's next invocation of it. In the registration-race form, the malicious script wins a race to register a tool under a target name before the legitimate tool ever registers, so the agent's first discovery of that name already resolves to the attacker's implementation. In both forms, the agent has no mechanism to detect that the live implementation behind a tool name changed, because WebMCP's own tool surface carries no binding between a tool's name and a stable origin or identity across the session -- the agent trusts the name, and whichever implementation currently answers to it. Demonstrated across a real testbed with benign and malicious page servers and three current frontier models (GPT-5.4, Claude Opus 4.6, Gemini 2.5-flash), 1,440 total runs across 12 conditions, 4 task scenarios, and the 3 models. The AbortSignal-hijack form achieves a 94% average malicious-tool-invocation rate (100% on GPT-5.4, 100% on Claude Opus, 82% on Gemini), and the registration-race form achieves 100% across all three models. A timing-sensitivity study confirms the AbortSignal form's success is strictly bounded by whether the hijack completes before the tool's first legitimate invocation: 100% success when the malicious replacement is in place before the agent's first call, and 0% at every later injection point tested, including immediately after the agent's first legitimate call to the original tool. Scoped specifically to this tool-identity-substitution mechanism, not the same paper's separate Tool Framing category (metadata- and description-based manipulation of an agent's understanding of a tool's role), which the paper's own discussion states partially overlaps with indirect prompt injection already covered elsewhere in this corpus; this record's mechanism involves no description, metadata, or natural-language content manipulation of any kind. Distinct from AVE-2026-00074 (Dead Anchor Reclamation): that record's mechanism is an external identity anchor (a GitHub owner, package name, or domain) that was live when a skill was authored and has since decayed into an unclaimed, re-registerable state over an external, slow timescale. This record's mechanism is a live, in-session, client-side tool registry manipulated via a browser API in real time, with no external decay, no waiting period, and no registry outside the WebMCP session itself. Distinct from AVE-2026-00080 (Runtime Agent Identity Substitution): that record's mechanism is an orchestrator accepting an unverified process at an agent's own routing position during a multi-agent retry cycle, with no credential or attestation check binding the response to the same agent instance. This record involves a single agent's own tool registry, poisoned by a third-party script on the page it is interacting with; no multi-agent orchestration, routing position, or retry cycle is involved anywhere in the mechanism. Distinct from AVE-2026-00082 (Local Skill Name Collision): that record's mechanism is two already-existing local files resolving to an identical name at discovery time, a static, filesystem-level condition requiring no attacker runtime action beyond placing a file. This record's mechanism is an active, live browser API call (AbortSignal) or registration-order race, executed during an active session by a malicious third-party script, with no local files or discovery roots involved at all. Distinct from AVE-2026-00002 (Tool Description Behavioral Injection): that record's mechanism is content-level injection within a tool's own description field, requiring the model to be steered by natural-language directives it reads. This record requires no description, schema, or natural-language content manipulation whatsoever; the malicious tool's own description can be entirely accurate, the substitution happens purely at the registry-identity level, invisible to any defense that only inspects tool-description text.", + "aivss_score": 7, + "cvss_base_vector": "CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:H/SI:H/SA:L", + "owasp_mcp": [ + "MCP03" + ], + "owasp_asi": [ + "ASI03" + ], + "mitre_atlas": [ + "AML.T0074" + ], + "nist_ai_rmf": [], + "behavioral_fingerprint": "A tool an agent has already discovered, and in some cases already invoked, within a live WebMCP session is unregistered (via a browser lifecycle API such as AbortSignal, or by losing a registration-order race before it ever registers) and a malicious replacement is registered under the exact same tool name, by a third-party script executing on the same page rather than by the tool's own origin.

MCP03 remains the best available category among the ten (the same choice this corpus already made for AVE-2026-00082's structurally similar name-collision mechanism, after MCP09 was checked and rejected there as an infrastructure-governance category, not a client-side registry-identity problem). owasp_asi mapped to ASI03 (Identity and Privilege Abuse) after reading the full 2026 PDF text directly: its own worked example, 'Synthetic Identity Injection: Attackers impersonate internal agents by using unverified descriptors... to gain inherited trust and perform privileged actions under a fabricated identity,' is a close structural match with 'tool' substituted for 'agent' -- a malicious tool assumes an unverified descriptor (its name) to inherit the trust the agent already extends to it. mitre_atlas mapped to AML.T0074 (Masquerading) after confirming its live text directly in ATLAS.yaml: 'the name or location of an object... is manipulated or abused for the sake of evading defenses and observation... giving legitimate task or service names' is a direct, unstretched match for a malicious tool registered under an existing, legitimate tool's exact name. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly: no subcategory beyond the same generic security-evaluation or third-party-risk boilerplate already found non-specific for the other records in this sourcing pass fits this mechanism any more precisely." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "sandbox", + "llm" + ], + "derivable_into": [ + "credential-exfiltration" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP03-2025%E2%80%93Tool-Poisoning.md", + "read_date": "2026-09-27" + }, + "owasp_asi": { + "version": "2026", + "read_date": "2026-09-27", + "source_url": "https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/" + }, + "mitre_atlas": { + "version": "5.6.0", + "read_date": "2026-09-27", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/main/dist/ATLAS.yaml" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00087", + "schema_version": "1.3.0", + "status": "active", + "title": "Agentjacking: a crafted tool response visually mimics a trusted system template to hijack an agent", + "attack_class": "Prompt Injection - Tool Response Template Mimicry", + "severity": "HIGH", + "description": "A monitoring or diagnostic integration exposes an MCP server whose ingest endpoint is designed to be publicly writable, a deliberate architectural choice so that unauthenticated clients (a user's own browser, for instance) can report events without holding a full credential. An attacker who obtains the write-only ingest credential, often trivially recoverable from a target's own public frontend JavaScript, POSTs a crafted event directly to that ingest endpoint, controlling the entire payload structure. The injected event embeds carefully formatted markdown, headings, code blocks, and a fabricated resolution or remediation section naming an executable command, within standard fields of the event schema, styled to be visually indistinguishable from the integration's own authentic, system-generated output. When a developer later asks their AI coding agent to investigate the resulting error or event, the integration's own MCP server returns the poisoned event to the agent as diagnostic data. The agent's own handling of MCP tool responses treats this returned data as authoritative system output rather than as untrusted external content requiring the same scrutiny as user-supplied input, and because the markdown formatting mirrors the integration's authentic template exactly, there is no visual or structural cue distinguishing the compromise from a genuine event. The agent, unable to distinguish the attacker's embedded instruction from legitimate remediation guidance, executes the suggested command with the developer's own full privileges. Demonstrated concretely against Sentry, a widely deployed error-tracking and performance-monitoring platform, using its DSN (Data Source Name), a public, write-only credential intentionally embedded in frontend JavaScript by design, requiring no additional authentication to submit events. Testing across three current AI coding agents, Claude Code, Cursor, and OpenAI Codex CLI, achieved an 85% exploitation success rate. Tenet Security identified at least 2,388 organizations with publicly exposed Sentry DSNs that could be used to inject malicious events by this method. Sentry itself has acknowledged the underlying issue as 'technically not defensible' given the DSN's intentionally public-write design, and has activated a narrow content filter blocking one specific payload string rather than a structural fix. The attack bypasses EDR, WAF, IAM, VPN, Cloudflare, and firewall defenses entirely, because no conventionally malicious artifact, no malware signature, no anomalous network behavior, exists anywhere in the chain: every request is a legitimately formatted, protocol-valid event submitted to an endpoint explicitly designed to accept unauthenticated writes. Distinct from AVE-2026-00044 (Async Task Result Poisoning): that record's own stated distinguishing property, explicitly named in its description, is a temporal gap between task dispatch and a later, separate turn's result consumption, which is what it identifies as bypassing synchronous safety checks. This record's mechanism is a synchronous MCP tool call and response within a single interaction, a developer asks the agent to investigate an error and the poisoned response returns immediately, with no temporal gap, no task dispatch, and no later-turn consumption pattern anywhere in the mechanism. Distinct from AVE-2026-00043 (MCP App UI Payload Injection): that record's mechanism is instructions hidden in non-rendered elements, hidden divs, alt attributes, SVG metadata, invisible to the user while still processed by the model. This record's malicious content is fully rendered and visible, exactly as the legitimate system's own output would be; its evasion technique is visual mimicry of an authentic template, the structurally opposite concealment strategy from hiding content the user cannot see. Distinct from AVE-2026-00042 (REPL Code Mode Payload Injection): that record's mechanism is tool-result content containing escape sequences or string terminators that break out of a data context directly into a dynamically constructed eval() or exec() code string, a syntactic code-injection technique.

the integration is naturally queried in the course of the agent's own normal diagnostic work, and the mechanism is definitionally about the agent's own MCP tool-calling capability. dynamic_identity scored at maximum (1): the entire technique is centered on visually mimicking the integration's own authentic, system-generated template so precisely that no formatting or structural cue distinguishes the compromise, genuine template-identity mimicry rather than a missing re-validation step on an honest, unchanged identity. natural_language_input scored at maximum (1): unlike the structural, syntactic mechanisms in AVE-2026-00084 and AVE-2026-00086 from the same sourcing pass, this mechanism's entire exploitation step is the agent reading natural-language, markdown-formatted content and being persuaded, as a reasoning act, that it represents legitimate guidance, a natural-language-input mechanism in the most direct sense. data_access and external_dependencies scored at maximum (1): demonstrated impact is arbitrary command execution with full developer privileges, and the mechanism is specific to integrations whose own ingest architecture accepts unauthenticated or partially-authenticated writes, a real, measured, integration-specific dependency. non_determinism scored 0.5: the 85% success rate reflects real, non-total variance across the three tested agents rather than a uniform result. persistent_memory scored 0.5: the malicious event persists in the integration's own event store and can be re-triggered whenever the same error is investigated again, a real but partial persistence property, distinct from a full cross-session standing capability change. multi_agent and self_modification scored 0: the mechanism is single-agent and does not involve the component altering its own instructions or runtime. cvss_base_vector mirrors the reasoning already applied across this sourcing pass: network-delivered (AV:N), low complexity (AC:L), a real precondition requiring the attacker to obtain the target's own ingest credential (AT:P, though the source's own finding that 2,388 organizations have publicly exposed credentials means this precondition is often trivially satisfied in practice), no additional privilege or unusual user interaction beyond the agent's own normal diagnostic workflow (PR:N/UI:N), full confidentiality/integrity impact given arbitrary command execution (VC:H/VI:H, SC:H/SI:H), and low availability impact at either layer (VA:L/SA:L) since this is not primarily a denial-of-service-shaped class. thm set to 1 (mechanism real and demonstrated): a real, disclosed, reproduced attack against a specific, named, widely-deployed production integration, with a measured 85% success rate across three current production coding agents and a real, acknowledged response from the affected vendor, not a theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): the affected vendor's own response was a narrow, single-payload-string content filter rather than a structural fix, and the vendor itself states the underlying architecture is 'technically not defensible' given the credential's intentional public-write design -- no standard practice for provenance-verifying tool response content exists yet across the evaluated agents. owasp_mcp mapped to MCP06 (Intent Flow Subversion) after reading the category's full primary-source text directly (same commit as prior records in this sourcing pass, 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own vulnerability checklist names 'Agent treats MCP resource text or tool outputs as potential instructions rather than passive data' verbatim, a precise, unstretched match for this record's own core failure, the strongest MCP Top 10 fit found across this entire sourcing pass. owasp_asi mapped to ASI01 (Agent Goal Hijack) after reading the full 2026 PDF text directly: its own description names 'deceptive tool outputs' explicitly among the techniques by which 'attackers can manipulate an agent's objectives, task selection, or decision pathways,' and its own first Example Attack Scenario, EchoLeak, a zero-click indirect prompt injection silently triggering hidden instructions via content an agent processes as trusted, is structurally analogous. mitre_atlas mapped to AML.T0051.001 (Indirect, a child of LLM Prompt Injection) after confirming its live text in ATLAS.yaml directly: 'an adversary may inject prompts indirectly via a separate data channel ingested by the LLM' is a precise, unstretched match, and the same technique already grounds AVE-2026-00044's mapping for a structurally similar external-data-channel injection mechanism, reused here because the role genuinely matches, not forked unnecessarily. nist_ai_rmf confirmed empty after checking the actual NIST AI 100-1 text directly:

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "read_date": "2026-09-05" + }, + "nist_ai_rmf": { + "pin_status": "unknown", + "read_date": "2026-10-15" + } + } + }, + { + "ave_id": "AVE-2026-00081", + "schema_version": "1.3.0", + "status": "active", + "title": "Lingering authority: a task-scoped capability outlives the episode that justified it", + "attack_class": "Persistence - Lingering Authority", + "severity": "MEDIUM", + "description": "An agent is granted a temporary resource or effect capability -- a tool permission, credential, or access token -- scoped to a specific task, subgoal, or episode.

An agent's skill router typically discovers skills across several local roots of differing trust (e.g. a user-level directory the operator controls directly, and a workspace-level directory any collaborator with repository write access can also write to), then flattens all discovered skills into one name-keyed lookup with no per-root namespace separation. When two skills collide on the same resolved name, whichever the router resolves last silently shadows the other, with no content-level warning, conflict indicator, or operator-visible signal that a collision occurred at all. An attacker who can write to a lower-trust root can therefore plant a skill sharing the exact resolved name of an existing trusted skill from a higher-trust root and have their skill invoked in the trusted skill's place.

MCP09 (Shadow MCP Servers) was considered and rejected after reading its real text: that category describes unregistered/ungoverned server deployments as an infrastructure-visibility problem, not a client-side skill-namespace collision -- a worse fit than MCP03 despite 'shadow' resonating with 'shadowing' at the label level, exactly the kind of same-word-different-mechanism trap OWASP/www-project-mcp-top-10#52 already documents elsewhere in this corpus. No category in the current 2025/ Top 10 cleanly describes a local name-collision-driven silent substitution; flagging this as a real gap worth raising with that project rather than forcing a second stretch tag. owasp_asi left empty after checking all ten categories' real primary-source text directly (genai.owasp.org, 'OWASP Top 10 for Agentic Applications 2026', download/52117): ASI03 (Identity and Privilege Abuse) was the closest candidate but its real mechanism is agent-to-agent delegation-chain and credential-cache exploitation, not a local file-resolution collision with no identity claim involved; ASI02, ASI06, ASI09, and ASI10 were also read directly and ruled out on the same basis. nist_ai_rmf left empty rather than copying this corpus's own dominant (MAP-1.5, MEASURE-2.5, MANAGE-1.3) pattern, which appears on 25 of roughly 56 tagged records: checked all three subcategories against the real NIST AI 100-1 text (Tables 2-4) directly, and all three are generic organizational-process subcategories (documented risk tolerance, model validity/reliability testing, documented risk-response planning) that don't describe this record's specific mechanism any more than they'd describe nearly any other AI risk finding -- a strong signal this corpus-wide pattern is unverified boilerplate rather than a genuine per-record mapping, worth a dedicated nist_ai_rmf audit mirroring the earlier owasp_asi audit (issue #196), not something this one record's drafting should silently perpetuate." + }, + "evidence_kind_default": "config_schema", + "detection_stage": "static_detection", + "detection_layer": "registry_metadata", + "confidence_baseline": 0.9, + "evidence_vantage": "artifact", + "evidence_basis_engines": [ + "pattern" + ], + "derivable_into": [ + "rug-pull-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/tree/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025", + "read_date": "2026-09-09" + }, + "mitre_atlas": { + "version": "5.6.0", + "commit": "41d4f5ca4112f0e492ffaa3ebff07dc80a75afa5", + "source_url": "https://raw.githubusercontent.com/mitre-atlas/atlas-data/41d4f5ca4112f0e492ffaa3ebff07dc80a75afa5/dist/ATLAS.yaml", + "read_date": "2026-09-09" + } + } + }, + { + "ave_id": "AVE-2026-00083", + "schema_version": "1.3.0", + "status": "active", + "title": "Silent guardrail comparison failure: a protection mechanism that executes but never evaluates its verdict", + "attack_class": "Trust Boundary - Silent Guardrail Comparison Failure", + "severity": "MEDIUM", + "description": "A protection mechanism -- a guardrail, an approval gate, a judge or eval scorer, a policy check -- is present in a component's own code (or in the agent framework, SDK, or proxy library implementing it), is invoked on every request that reaches it, and its logs, code coverage, and test suite all show it executing normally. Despite this, the mechanism's own comparison, branch, or aggregation logic never genuinely evaluates the real input against its intended deny condition, so it returns the result read downstream as 'permitted' or 'no violation' regardless of, or for a wide class of, the actual input. Five structural forms produce this behavior, each independently reproduced against shipped, real-world code by arian-gogani (github.com/arian-gogani/failopen): (1) an elif intended to catch a global or catch-all verdict is bound to the wrong enclosing conditional, making it unreachable once an unrelated, narrower branch is taken; (2) a verdict or classification value is declared as a bare, loosely-typed string -- often arriving from a model completion, json.loads, or a subprocess -- and compared with an exact == against a single expected literal, so any other phrasing (a full sentence, different casing, a synonym, an empty string) falls through to the permissive branch, reproduced in deepeval's role-violation, prompt-alignment, and conversation-completeness metrics scoring a judge verdict of 'Yes, the model violated its assigned role' as full compliance (confident-ai/deepeval#3283), litellm's Aporia guardrail hook forwarding content marked 'modify' or 'rephrase' unmodified because only the literal 'block' is handled (BerriAI/litellm#41097), and a microsoft/autogen governance sample executing on any verdict string it does not recognize as 'deny' (microsoft/autogen#7960); (3) the same approval or validation helper is invoked from two or more call sites with opposite defaults for identical, malformed input -- raising on one path, silently returning a permissive default on the other -- reproduced in openai-agents-python's needs_approval evaluator diverging between its core runner (raises UserError) and its realtime session (returns False, read as approval granted) for the same unrecognized configuration value (openai/openai-agents-python#5024), and guardrails-ai's on_fail default diverging between its Python API (raises) and its RAIL config path (silently becomes a no-op) for the same validator (guardrails-ai/guardrails#1656); (4) an error-handling or absent-dependency path omits, or an unparseable value silently coerces into, the specific state the downstream verdict logic reads, so an errored or unreachable check counts as passing -- reproduced in AutoGPT classic's Agent Protocol server path constructing an agent with no permission_manager (the CLI entry point in the same codebase always supplies one), so Agent.execute()'s own 'if self.permission_manager:' guard silently skips the entire deny-list check only on the network-facing path, and in protectai/rebuff's LLM detection tactic, where an unparseable model completion parses to NaN and 'NaN > threshold' is always false; and (5) a security verdict is computed with all() or any() over a collection that a reachable configuration or caller-supplied path can leave empty, so the aggregate reports a full pass having evaluated zero checks -- all([]) is True by definition, with a live, confirmed instance in a guardrail-orchestration product's own verdict aggregation currently under coordinated disclosure and deliberately unnamed by the source pending vendor response. The same measurement found zero instances of one detectable shape of this defect across 1,128,865 lines of mature, heavily reviewed Python (certbot, bandit, pyjwt, sigstore-python, python-tuf, detect-secrets) and fifteen confirmed instances across thirty-six projects whose enforcement code is roughly eighteen months old or newer (twenty-one read and found clean), indicating this concentrates in newly-written enforcement layers rather than software broadly. The common, externally observable behavior across all five forms -- and the reason this is drafted as one behavioral class rather than five separate ones -- is that the mechanism's own telemetry is indistinguishable from a genuine pass: the check appears in logs and traces, the deciding line is marked covered because it executes, and a project's own test suite can stay green with the defect present, because tests are typically written from the same understanding of the input space as the code being tested. Distinct from AVE-2026-00063 (Approval Gate Bypassed via Declarative Configuration): that record's mechanism is a config flag that visibly and legibly disables a check, discoverable by a reviewer reading the config file itself. This record's check is never disabled or bypassed; it is invoked and executes, and is unreachable, mistyped, divergent, or blind to real state at the code level -- invisible to a config or instruction-text review and requiring source-level or behavioral analysis to surface. Distinct from AVE-2026-00076 (Natural-Language Steering of an Approval Classifier Subagent): that record's classifier genuinely evaluates its real input and is merely biased toward a looser decision by adversarial natural-language steering text reaching it. This record's mechanism produces the permissive result independent of any steering content at all -- the comparison itself is structurally incapable of reaching its deny branch, or is blind to the real input, regardless of what that input says. Distinct from AVE-2026-00078 (Unverified Multi-Agent Consensus) and AVE-2026-00079 (Plan-to-Execution Binding Bypass): both describe an orchestrator's own total absence of a verification step (no quorum check exists; no plan-to-trace binding exists anywhere in the architecture). This record's mechanism is the inverse -- a verification step does exist, is invoked, and is intended to run, but its own internal logic never reaches or genuinely evaluates the comparison that would make it work. Distinct from AVE-2026-00038 (Unbounded Tool Use or Sub-Agent Spawning): that record is a component instructing an agent to ignore scope boundaries entirely, with no gating mechanism present in the architecture at all. This record requires a real gating mechanism to be present, configured, and invoked, whose own internal comparison then fails silently.

non_determinism because forms 1/3/4/5 are deterministic control-flow or aggregation defects that fire identically every run, while form 2's failure rate depends on how an LLM judge happens to phrase its verdict on a given call; natural_language_input because form 2 is centrally about natural-language verdict phrasing defeating an exact-match comparison, while forms 1/3/4/5 are pure structural/syntactic defects (an elif's scope, a divergent default, an emptied collection) that would occur identically for a boolean or enum verdict; data_access because the actual reach of a defeated guardrail varies by which action it was gating, from an eval score (low) to unrestricted shell execution (AutoGPT, high). multi_agent, self_modification, and dynamic_identity scored 0: the mechanism is single-component, does not require the component to alter its own instructions, and involves no impersonation or identity claim of any kind. persistent_memory scored 0: the underlying code defect is a static, load-bearing property of the shipped software rather than an effect that persists in the agent's own session or memory store, and a single bypass event does not itself write a lasting belief or credential into agent state the way AVE-2026-00019 or AVE-2026-00081 describe. thm set to 1 (mechanism real and demonstrated): all five forms are reproduced with an executable, one-command script against the actual shipped package or sample (not a retyped approximation) across seven independent, unrelated codebases, plus a published static detector with measured real-world yield -- this is a working exploit description across multiple, independently-confirmed targets, not a single theoretical scenario. mitigation_factor set to 1 (no broadly effective, ecosystem-wide mitigation exists yet): unlike a known fix such as re-enabling TLS verification or pinning a dependency, there is currently no standard, widely-adopted practice for this defect class -- the primary source's own stated goal is establishing an identifier and vocabulary precisely because none exists yet, and the source's own detector implements only one of five forms. cvss_base_vector reflects a network-reachable check (AV:N) requiring no special attacker positioning, privilege, or user interaction (AT:N/PR:N/UI:N) to encounter, full confidentiality/integrity compromise at the mechanism's own decision boundary and at whatever it gates (VC:H/VI:H, SC:H/SI:H) since the defect grants exactly the access or action the guardrail existed to withhold, and no availability impact at either layer (VA:N/SA:N) since this is not a denial-of-service-shaped class. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text directly (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document, commit 165fe0f78ef104459237b4a8e0f6e78db9b02391): its own description states the category covers cases where 'MCP servers, tools, or agents fail to properly verify identities or enforce access controls during interactions' and where 'authorization flaws occur when... Agents or users can perform actions beyond their intended privileges' -- the consequence this record produces exactly. Flagged honestly as an imperfect fit: MCP07's own worked checklist (hard-coded secrets, client-side-only enforcement, unverified caller-identity metadata, missing scope validation) is entirely about identity/token-based authorization being absent or weak, not about a present, invoked authorization check whose own comparison logic is structurally defective -- the closer framing is CWE-693/Protection Mechanism Failure at the code-weakness level, which OWASP's MCP Top 10 has no direct analogue of. MCP03 (Tool Poisoning), MCP06 (Intent Flow Subversion), MCP08 (Lack of Audit and Telemetry), and MCP09 (Shadow MCP Servers) were also read in full and rejected: MCP03 and MCP06 require a compromised or adversarial tool description/context altering agent behavior, which this record's mechanism does not need (four of five forms fire on entirely benign input); MCP08 is the near-opposite of this record's mechanism, since the defective check still produces normal-looking logs and telemetry rather than an absence of them; MCP09 concerns unregistered server deployments, an infrastructure-governance problem unrelated to a code-level comparison defect. owasp_asi confirmed empty after reading the full primary-source PDF directly (genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026, 'OWASP Top 10 for Agentic Applications 2026', December 2025, all ten ASI01-ASI10 category descriptions read in full, not just titles): ASI03 (Identity and Privilege Abuse)'s own TOCTOU example concerns permissions validated once at workflow start and never re-checked as they change, a lifecycle/timing gap distinct from a same-request comparison that never evaluates at all; ASI02 (Tool Misuse and Exploitation) requires an agent applying an otherwise-legitimate tool unsafely, not a defect in the enforcement code itself; ASI09 (Human-Agent Trust Exploitation) is specifically about human over-reliance on an agent's own persuasive output, not a code-level guardrail defect with no human judgment involved. No category cleanly describes a present, invoked protection mechanism whose own comparison is structurally incapable of reaching its deny branch; a genuine gap, matching the primary source's own independent finding that this is also absent from CSA's named March 2026 gap list. mitre_atlas confirmed empty after fetching and searching the live ATLAS.yaml (mitre-atlas/atlas-data, main branch) directly for guardrail/verdict/bypass/evasion/defense-evasion language: AML.T0054 (LLM Jailbreak) requires adversarial prompting to induce a model to override its own guardrails, a fundamentally different mechanism from a code-level comparison defect that fires independent of any adversarial input; AML.T0107 (Exploitation for Defense Evasion) was the closest candidate, and its second sentence ('vulnerabilities may exist in defensive security software that can be used to disable or circumvent them') is a real textual echo, but the technique's controlling definition requires 'a programming error... to execute adversary-controlled code', which is not required by four of this record's five forms (no code execution or active exploitation is needed; the defect misfires on ordinary, even benign, requests) -- a real gap rather than a stretch worth forcing. nist_ai_rmf confirmed empty after reading the actual NIST AI 100-1 text (Tables 1-4) directly: MEASURE 1.2 ('effectiveness of existing controls are regularly assessed and updated') was the closest candidate, but per this project's own prior audit (issue #196) this is exactly the kind of generic organizational-process subcategory that could describe nearly any AI risk finding and was flagged as likely unverified boilerplate elsewhere in this corpus -- not a mapping specific to this record's mechanism, so left empty with this note rather than perpetuated." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.45, + "evidence_basis_engines": [ + "pattern", + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ], + "framework_sources": { + "owasp_mcp": { + "commit": "165fe0f78ef104459237b4a8e0f6e78db9b02391", + "source_url": "https://github.com/OWASP/www-project-mcp-top-10/blob/165fe0f78ef104459237b4a8e0f6e78db9b02391/2025/MCP07-2025%E2%80%93Insufficient-Authentication%26Authorization.md", + "read_date": "2026-09-21" + } + }, + "verification_basis": "artifact_reconstructed" + }, + { + "ave_id": "AVE-2026-00088", + "schema_version": "1.3.0", + "status": "active", + "component_type": "agent", + "title": "Sandbox side-effect trust handoff: an agent-written workspace file is run by a trusted component outside the sandbox", + "attack_class": "Sandbox Escape - Side-Effect Trust Handoff", + "severity": "MEDIUM", + "description": "A coding agent runs inside a sandbox that lets it create and modify files in the workspace but not run arbitrary commands on the host. Content the agent processes (a README, a project note, a dependency's documentation) steers it into writing a file the sandbox allows: a hook definition, an editor task, Git metadata, the agent tool's own project configuration, or an interpreter inside a virtualenv. A more-privileged component outside the sandbox later reads that file and executes it as trusted configuration or code: the agent harness's own hook engine or startup configuration loader, the editor's task runner, or an editor extension that runs Git or discovers Python interpreters. That component does not distinguish agent-written files from user-authored ones and does not run what it consumes under the sandbox's execution policy, so the agent's side effect executes on the host with the user's privileges even though the agent process itself never left the sandbox. Demonstrated across vendors: Cursor ran a Stop hook from an agent-written .claude/settings.local.json at the end of the turn (CVE-2026-48124), ran Git hooks the agent planted in improperly protected .git settings (CVE-2026-26268), ran a core.fsmonitor helper the agent placed in a repository created with --separate-git-dir past a literal .git/config deny rule (patched in 3.0.0), and ran a virtualenv interpreter the agent replaced when the Python extension invoked it outside the sandbox (CVE-2026-73217). Claude Code loaded SessionStart hooks from a .claude/settings.json the sandbox let the agent create because the file was absent at startup (CVE-2026-25725). Antigravity's write tools let the agent drop a runOn: folderOpen task into .vscode/tasks.json, which VS Code's task runner executed on the host on the next open. Codex CLI let apply_patch create .codex/config.toml, whose notify command runs outside the sandbox, and Gemini CLI mounted the user's settings.json writable into its container. Distinct from AVE-2026-00064 (Zero-click code execution via project-load auto-run configuration): that record covers attacker-supplied project configuration that auto-runs on project load, a pre-consent boundary; here the writer is the sandboxed agent, the file usually does not exist in the repository at all, and the trigger is usually not project load, so confirming before project-load auto-run does not close it. Distinct from AVE-2026-00054 (Code-execution sandbox escape via JavaScript prototype-chain traversal): there a payload breaks the sandbox itself; here the sandbox works as designed and a component it does not govern does the executing.

The overlap is real for one vector of CVE-2026-48124, whose advisory names both 'a malicious workspace' and 'an agent-created file'; it is cited here for the agent-written PoC Pillar published. Also compared field by field with AVE-2026-00054 (runtime: the sandbox itself is broken by a prototype-chain payload; here the sandbox works as designed), AVE-2026-00050 (runtime: hook registration beyond a component manifest at session init; no manifest is involved here), AVE-2026-00084 (registry_metadata: a vetted plugin's update rebinds a hook; here the change is the agent's own write), AVE-2026-00071 (registry_metadata: daemon redirect to remote infrastructure), AVE-2026-00075 (skill_file: bytecode diverging from reviewed source) and AVE-2026-00063 (an approval flag in config; overlaps only where an agent-written config also sets one, as in Cymulate's Codex approval_policy, and the executing step there is still notify run outside the sandbox). entry_class model_generated reused rather than forked: as in AVE-2026-00056, the payload is something the agent itself produces (a file it writes), not something it reads. Q6 (replace the LLM with a deterministic program with the same workspace write access): the flaw partly survives, since any sandboxed process whose output a privileged consumer trusts can escape the same way. What remains agentic: the sandbox exists to contain a model steered by untrusted content, and the attacker needs only text the model reads rather than code execution inside the sandbox, because writing arbitrary workspace files is the agent's normal capability; the decision to write comes from model reasoning over injected content (the CVE-2026-26268 advisory's own words: 'A malicious agent (ie prompt injection)'); and in most instances the trusted consumer is the agent harness itself (hooks, notify, startup config) treating its own agent's writes as the user's configuration. Classified A rather than E for that reason, with the partial survival stated. autonomy scored 1: once the file is written, the trusted component executes it on its own trigger with no further attacker interaction and no approval prompt. tool_use scored 1: the mechanism is the agent's own file-write or shell tool producing the artifact. non_determinism scored 0.5: exploitation depends on the model following injected content, which varies run to run (OpenAI's own closure of Cymulate's Codex report cited prompt injection). self_modification scored 0.5: in the hook, notify and settings instances the agent writes its own harness's configuration and so changes the agent runtime's later behavior; the Git, editor-task and virtualenv instances change a different component, so not 1. dynamic_identity scored 0.5: the consumer extends user-authored trust to an agent-written file, a trust-anchor confusion over authorship, scored as AVE-2026-00084 scored inherited vetting trust. persistent_memory scored 1: the written file stays on disk and re-executes on every later trigger (the CVE-2026-25725 advisory calls them 'persistent hooks'; Cymulate's Gemini settings persist across directories). natural_language_input scored 0: the delivery is natural language, but the exploit step at the boundary is structural (a configuration file executed by a component), which the scoring reference scores 0. data_access scored 1: execution runs as the user on the host, with the user's keys, tokens and files. external_dependencies scored 1: severity depends entirely on which host-side consumer trusts which file (a hook engine, a task runner, a Python or Git extension). multi_agent scored 0. cvss_base_vector follows the CVE-2026-25725 advisory's own vector: network-borne delivery through content the agent reads (AV:N), low complexity (AC:L), a precondition on sandbox or auto-run mode and on the agent following the content (AT:P), no privileges (PR:N), passive user interaction such as continuing the session or restarting the tool (UI:P), and full host impact (VC:H/VI:H/VA:H). The Cursor advisory scored its instance higher (8.5, AV:L/AT:N) and CVE-2026-26268 was scored 8.0 under CVSS 3.1; 7.7 is the most conservative vendor reading of the same handoff. thm set to 0.90 (PoC exists, not exploited in the wild): every instance cited has a working PoC and most have a vendor-confirmed fix, but no in-the-wild exploitation is reported. mitigation_factor set to 1: fixes are per path and per product (Antigravity's blocklist missed tasks.json, Cursor's rule missed .git-alt), Google downgraded one instance, OpenAI closed another as informational and Gemini CLI's was unresolved at disclosure; no ecosystem-wide standard mitigation exists. MEDIUM despite host code execution, honestly, as with AVE-2026-00064: a narrow handoff mechanism with no multi-agent component. owasp_mcp mapped to MCP05 (Command Injection & Execution) after reading the category text at commit 165fe0f78ef104459237b4a8e0f6e78db9b02391: its description covers instructions hidden in context causing the agent to generate malicious commands, and its checklist names 'No runtime sandboxing isolates tool execution from the host system' and 'Execution occurs across different contexts (e.g., generating commands on one server that execute on another without re-validation)'. MCP02 was read and rejected (it is permission scope drifting over time). owasp_asi mapped to ASI05 (Unexpected Code Execution) after reading the 2026 document: it covers execution 'that leads to host or container compromise, persistence, or sandbox escape', and its Example 4 is an agent-generated object passed to another component and executed without validation; the ASI02 text routes code-execution outcomes to ASI05, and ASI03 (identity and delegation abuse) was read and rejected. mitre_atlas mapped to AML.T0105 (Escape to Host) and AML.T0081 (Modify AI Agent Configuration) after reading both in the live ATLAS.yaml (v5.6.0): T0105's own text names 'modifying an AI Agent's configuration to disable safety features or user confirmations could allow the adversary to invoke tools to be run on host environments rather than in the sandbox'; T0081 covers the subset where the written file is the agent harness's own configuration (Claude Code and Cursor hook settings, Codex config.toml, Gemini settings.json), not the Git, editor-task or virtualenv instances.

The harness, however, computes that scope from a value the model supplies in the tool call itself, such as the command's working directory, rather than from the session's own root. Content the model reads (an MCP tool response, a web search result, a README) steers it to set that value to a location outside the workspace, and the sandbox grants write access there. The agent can then write the sandbox's own helper binary, the user's shell startup files or launch agents without approval, so later commands run unsandboxed. The model does not break the boundary; it sets it. Demonstrated in two products. Codex CLI 0.2.0 to 0.38.0 could treat a model-generated cwd as the sandbox's writable root, including paths outside the folder where the user started the session (CVE-2025-59532); the fix separates the command's working directory from the directory the sandbox policy is computed from. Cursor before 3.0 added the run_terminal_cmd tool's optional working_directory parameter to the sandbox's allowed write list whenever the model set a non-default value (CVE-2026-50548, part of Cato AI Labs' DuneSlide research), and the proof of concept overwrote Cursor's cursorsandbox helper. Distinct from AVE-2026-00053 (Path traversal via unsanitized path parameter in an MCP file handler): there a handler fails to contain a caller-supplied path against its own fixed scope; here the value is honored exactly and the policy layer derives the boundary from it. Distinct from AVE-2026-00054 (Code-execution sandbox escape via JavaScript prototype-chain traversal): there a payload breaks the runtime's isolation; here the isolation works as configured, and the configuration came from the model.

Q6 (replace the LLM with a deterministic program): the flaw, in the form that matters, does not survive. A conventional program does not take its sandbox boundary from the output of the component the sandbox exists to contain; Cato AI Labs' own write-up: 'Traditionally, a remote attacker cannot control the working directory of a sandboxed operation.' Strongest counterargument: this is an ordinary input-validation bug (the Advisory Database files CVE-2025-59532 as CWE-20), and a deterministic sandbox that derived its root from an untrusted request would have the same flaw. Answer: the structural error can exist without a model, but the input only becomes attacker-reachable because a model generates it, so the constrained party, a model steerable by any content it reads, is the party choosing the boundary; both vendor fixes confirm the framing by separating model-supplied execution parameters from user-established policy (Codex's fix commit splits command_cwd from sandbox_policy_cwd). Classified A rather than E. autonomy scored 1: once the model sets the parameter, the sandbox grants the scope and writes proceed with no approval in auto-run mode. tool_use scored 1: the mechanism is a tool-call parameter. non_determinism scored 0.5: exploitation depends on the model following injected content (Cursor initially rejected the report on threat-model grounds about MCP misuse, not reproducibility, but model compliance still varies). self_modification scored 0.5: the demonstrated chain overwrites the agent's own sandbox helper so later commands run unsandboxed, a change to the agent runtime, though the class itself is the widened scope, not the helper overwrite. dynamic_identity scored 0.5: the policy layer gives a model-supplied value the authority of the user-established session root, a trust-anchor confusion over who sets policy, scored as AVE-2026-00088 and AVE-2026-00084 scored theirs. persistent_memory scored 0.5: the escape happens within a session, but its demonstrated payloads persist (an overwritten sandbox helper, ~/.zshrc, ~/Library/LaunchAgents). natural_language_input scored 0: the delivery is natural language but the boundary step is a structured parameter value, which the scoring reference scores 0. data_access scored 1: arbitrary writes anywhere the process can write, leading to host command execution. external_dependencies scored 1: severity depends entirely on whether a specific harness derives its policy from the parameter (Codex CLI before 0.39.0, Cursor before 3.0). multi_agent scored 0. cvss_base_vector is the Codex advisory's own vector for CVE-2025-59532, the most conservative vendor reading (Cato scores both DuneSlide findings CVSS 9.8 under 3.1, Cursor rates CVE-2026-50548 Critical): network-borne injected content (AV:N), low complexity (AC:L), no attack-time precondition beyond the default auto-run sandbox (AT:N), low privileges as the vendor scored it (PR:L), passive user interaction (an innocuous prompt, UI:P), full impact (VC:H/VI:H/VA:H). thm set to 0.90 (PoC exists, not exploited in the wild): both instances have working PoCs and vendor fixes, with no reported in-the-wild exploitation. mitigation_factor set to 1: the fixes are per product, Cursor first rejected the report as outside its threat model, and Cato states it is disclosing further issues in other coding agents; no ecosystem-wide standard mitigation exists. owasp_mcp mapped to MCP05 (Command Injection & Execution) after reading the category text at commit 165fe0f78ef104459237b4a8e0f6e78db9b02391: its checklist names 'Agent outputs are not constrained to allowlists of permitted commands, arguments, or file paths' and 'No runtime sandboxing isolates tool execution from the host system'.

Report only: no record, schema file or script was changed, and none is proposed here. + +**Date:** 2026-10-31. **Records:** 89 (all `active`, schema 1.3.0, `aveproject/ave` `develop` at `dfb920f`). + +## Summary + +- 3 records have a stored `cvss_base` equal to the score their vector computes to (AVE-2026-00046, AVE-2026-00088, AVE-2026-00089). +- 85 records differ: 78 computed higher than stored (mean +1.03, up to +2.7) and 7 computed lower (mean -1.33, down to -4.2). Over the 85, computed minus stored has a mean of +0.84 and a mean absolute value of 1.06. +- 1 vector is not a valid CVSS v4.0 vector: AVE-2026-00066 uses `UI:R`, a CVSS 3.1 value. Both implementations reject it. +- Two independent implementations of the CVSS v4.0 equations agree on all 88 valid vectors. +- Neither explanation tested for the differences fits. The record notes say where the base came from for only 7 of the 85 differing records. + +## Why it matters + +OWASP AIVSS v0.8 takes a CVSS v4.0 base score as its baseline and warns against CVSS 3.1 inputs (section 3.1.1). Its equation adds the agentic uplift to the base (`AIVSS = (CVSS_Base + AARS) x Mitigation_Factor`, sections 3.3 and 3.4), so the base is the floor of the score: a record never scores below its `cvss_base` times its mitigation factor. Whatever AVE scores under v0.8 inherits this input whole. AVE's own equation (`((CVSS_Base + AARS) / 2) x ThM x Mitigation_Factor`) also counts it, as half of the average. See #395 for why the equation matters. + +## Method + +1. For each record, the CVSS v4.0 base score of `cvss_base_vector`, computed by two implementations: + - **`cvss` 3.6**, the Python library from Red Hat Product Security (`pip install cvss`), `CVSS4(vector).base_score`. + - **FIRST's own calculator source**, `FIRSTdotorg/cvss-v4-calculator` at commit `c5b0d409ae9f57c44264c6ce5f27d89298e1d32a` (a browser application, BSD-2-Clause). Its scoring files (`cvss_score.js`, `cvss_lookup.js`, `max_severity.js`, `max_composed.js`, `metrics.js`) were read first: they touch no network, file system or DOM. They were then run unchanged in a bare Node 20 `vm` context with only the globals they define, by the driver in the appendix, with each vector parsed and validated against the calculator's own `expectedMetricOrder`. The two codebases are written in different languages; the Red Hat group also contributes to FIRST's calculator, so they are independent implementations, not independent authors. +2. Sanity check of both on published reference vectors: `AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N` gives 9.3, the same with `SC:H/SI:H/SA:H` gives 10.0, and all impacts `N` gives 0.0, in both. +3. A stored base and a computed base are equal when they differ by less than 0.05. + +## Results + +| | Records | +|---|---| +| Vector valid, both implementations agree | 88 | +| Stored equals computed | 3 | +| Stored differs from computed | 85 | +| Vector invalid (both implementations reject it) | 1 | + +Size and direction of the 85 differences (computed minus stored): + +| Size of difference | Computed higher | Computed lower | +|---|---|---| +| 0.5 or less | 21 | 2 | +| over 0.5 to 1.0 | 24 | 2 | +| over 1.0 to 2.0 | 30 | 2 | +| over 2.0 | 3 | 1 | + +Where the stored values sit: 24 distinct values between 6.2 and 10, all to one decimal. The computed scores take 18 distinct values between 2.3 and 10; 67 of 88 are 9.0 or more, against 18 of 89 stored. 20 vectors set all three Subsequent System impacts (`SC`, `SI`, `SA`) to `H`. + +### The invalid vector + +`CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:R/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`: `UI:R` ("required") is a CVSS 3.1 user-interaction value. CVSS v4.0 has `UI:N`, `UI:P` (passive) and `UI:A` (active). Its stored base is 9. + +## Explanations tested + +**A. The stored numbers are CVSS 3.1 scores of the same metrics.** A v4.0 vector has no exact 3.1 equivalent, so twelve mappings were tried (Scope unchanged, or changed when any Subsequent impact is not `N`, or when any is `H`; `AT:P` ignored or read as `AC:H`; `UI:P` read as `R` or `N`), each scored with the `cvss` library's `CVSS3`. The most favourable mapping reproduces the stored base for 12 of 88 records (45 within 0.5); the other eleven do no better. Choosing the best of twelve overstates the fit, and it is still a small minority. **This does not explain the differences.** + +**B. The stored numbers were estimated by hand and have no fixed relation to the vector.** Over the 88 valid records the correlation between stored and computed is r = 0.46: a weak relation, with the stored values in a narrower, higher range. This is consistent with hand estimation and does not prove it. The record notes do not settle it: only 7 of the 85 differing records say in `aivss.notes` that `cvss_base` reflects a CVE or an NVD score; the other 78 say nothing about where the base came from. Whether a CVE-derived base is a CVSS 3.1 or 4.0 score is not stated either, and was not checked against NVD here. + +**Conclusion.** Neither explanation fits, and no cause is asserted. What is established is that the stored `cvss_base` cannot be derived from the stored vector for 85 of 88 valid vectors, and that the vector set itself has a problem (one invalid vector, and 20 with all Subsequent impacts `H`, which was not examined against each class). + +## Recommendation for the 2.0.0 migration + +1. **The CVSS vector is the authoritative input; the base is computed from it.** For each record, re-derive the v4.0 vector from the class's impact (the Subsequent System metrics deserve the most care: v0.8 says to assess them from what a compromised agent can reach through its tools, delegation and inter-agent paths, section 3.1.1), compute the base with a named implementation, and store both. +2. **Add a validator rule** that `cvss_base` equals the base score of `cvss_base_vector`, with the implementation and its exact version pinned in the development requirements, and a test that fails if the two implementations used here disagree on any record's vector. +3. **Do this inside the 2.0.0 migration, once.** Changing `cvss_base` before then would silently rescore the corpus under the 1.x equation; changing it during the migration changes it together with everything else that moves, and `revisions` records it. +4. Treat the invalid vector as a defect to correct in the same pass, not as an input. + +## What this audit did not do + +- It did not change any record, and does not say which of the stored base or the computed base is nearer the truth for any class. That is a judgement about each class's impact, and belongs to the re-assessment. +- It did not check any base against NVD, or any vector's metric choices against the class it describes. +- It tested two explanations, not every possible one. + +## Full table + +| Record | Stored `cvss_base` | Computed | Computed minus stored | Class | Vector | +|---|---|---|---|---|---| +| AVE-2026-00001 | 8.5 |

Additive changes (new optional `result.properties.*` fields) are non-breaking and do not increment the version. A change that widens what a conforming output may contain, such as a second accepted form for the AVE id, is non-breaking for emitters but can need more of a consumer, so it increments the minor version. **Revision note (2026-10-01):** the worked example, `taxonomies` block, and properties tables had gone stale against the live schema and corpus without the version number moving, which is itself the failure mode this section exists to prevent. Checked and corrected: `downloadUri`/`organization` were pointing at Bawbel-branded infrastructure (`api.piranha.bawbel.io`, "Bawbel Security Research") rather than AVE's own real, independent API and identity; the worked example cited `AVE-2026-00001` with `owasp_mcp`/`mitre_atlas` values that no longer matched the live record; `owasp_asi` and `nist_ai_rmf` existed on records with no documented SARIF representation at all. All of that is corrected above. None of it was a breaking change under this section's own rule, so the version stays v1.0; what changed is this document matching reality again, not the convention's own shape. **Revision note (2026-10-29):** added the recommended run properties `ave_catalog`, `ave_schema_version` and `ave_records_sha256`, which name the catalog release a scan used, now that releases are published with a manifest (`v1.2.0` onwards). Also stated what `taxonomies[].version`, `releaseDateUtc` and `downloadUri` hold, which this document had left unspecified: that same release's version, date and `ave-records.json`. Both examples moved from `1.1.0` to the `v1.2.0` release. The run properties are optional and no existing field was removed or changed, so the version stays v1.0. + +**Revision note (2026-10-31):** added form B, a second way to carry the AVE id (a tool's own `ruleId`, with `properties.ave_id` on the rule and on each result), because a tool that emits AVE ids in SARIF today does exactly that. Form A is unchanged. No field changed meaning and every output that was conformant still is, so this is a minor version, v1.1, not a major one; a consumer that read only `result.ruleId` must now also read `properties.ave_id` to see form B's ids.

here for issue #410. No record is changed by this document: it states what was decided and why, so that the pull requests that apply each decision can point at it. + +## What this covers + +The capability-vulnerability audit ([`docs/audits/capability-vulnerability-audit.md`](../audits/capability-vulnerability-audit.md)) classified 16 of 80 records as generic vulnerabilities (classification E): an existing CWE already names the weakness, so a record's claim to be a distinct AVE class rests on an agentic-specific distinction. The audit's own summary lists the 16 (line 2058). Thirteen are full seven-question sections; 00040, 00053 and 00060 are in the audit's compact section, a single line marked `**E**`, so a parser that reads only the full sections finds 13 and misses them. + +Discussion [#234](https://github.com/orgs/aveproject/discussions/234) has been open since 2026-08-29 on 00052, 00053 and 00060. On 2026-10-08 the maintainer proposed deprecating them, checked against the records (00052 and 00060 cite CWE-78, 00053 cites CWE-22, each says in its own text that it is an implementation flaw), and left it open for objections until 15 October. The cfgaudit crosswalk's author replied that none of the three is mapped to a cfgaudit rule, so nothing changes for them. The discussion had not been decided. + +| Record | Title | Audit decision, confidence | Decision | +|---|---|---|---| +| 00004 | Arbitrary code execution via shell pipe injection in agentic component | JUSTIFY, HIGH | JUSTIFY | +| 00005 | Recursive file system destruction via destructive command injection in agentic component | JUSTIFY, HIGH | JUSTIFY | +| 00033 | Unsafe Deserialization or Eval Instruction | JUSTIFY, HIGH | JUSTIFY | +| 00035 | Environment or Sensor Data Manipulation | JUSTIFY, MEDIUM | JUSTIFY-IF-WRITTEN | +| 00040 | Insecure Output - Unescaped Injection into Downstream System | JUSTIFY, no confidence stated | JUSTIFY | +| 00047 | Hardcoded credentials in agent component - API keys and secrets exposed in skill files | JUSTIFY, HIGH | JUSTIFY | +| 00049 | HTTP Host Header Injection via Agent-Initiated Request (BadHost) | JUSTIFY, LOW | DEFER | +| 00052 | Command injection via unsanitized tool-call parameter in MCP server implementation | JUSTIFY, LOW | REJECT | +| 00053 | Path traversal via unsanitized path parameter in MCP resource/file-handler implementation | JUSTIFY, LOW | REJECT | +| 00054 | Code-execution sandbox escape via JavaScript prototype-chain traversal | JUSTIFY, LOW | DEFER | +| 00060 | STDIO transport shell injection via unsanitized tool call parameters | JUSTIFY, MEDIUM | REJECT | +| 00061 | TLS certificate verification disabled in agent component configuration | DEPRECATE-OR-JUSTIFY, LOW | REJECT | +| 00062 | Unpinned dependency version allowing supply chain substitution | JUSTIFY-OR-MERGE, LOW | DEFER | +| 00072 | MCP server bound to all network interfaces with no authentication step (NeighborJack) | JUSTIFY, MEDIUM | JUSTIFY-IF-WRITTEN | +| 00073 | Telemetry or API endpoint redirect via static configuration value | JUSTIFY, HIGH | JUSTIFY | +| 00075 | Bytecode poisoning: compiled .pyc cache diverges from its own reviewed .py source | JUSTIFY, HIGH | JUSTIFY | + +- **JUSTIFY** (7): the record stays and its `vulnerability_rationale` states the agentic-specific distinction. 00004, 00005, 00033 and 00040 also need a primary source found. +- **JUSTIFY if written** (2): 00035 and 00072 stay only if their records state the agentic distinction and answer the audit's Q6 (would a deterministic program with the same flaw have essentially the same vulnerability?). If they are not written, they are rejected. +- **DEFER** (3): 00049, 00054 and 00062 stay as they are, deferred on 2026-10-31. Before the 2.0.0 release each either states the distinction or is rejected (00062 may instead be merged into an active record). +- **REJECT** (4): 00052, 00053, 00060 and 00061 get `status: rejected`, through one public decision on #234. The pull request that changes their status opens a week after that decision is posted. + +## The shared rationale + +The weakness these records name is conventional, and the audit says so: its Q6 answer for 00004 is that a deterministic program which pipes untrusted configuration into a shell has the same flaw. What makes them AVE classes is the channel the weakness arrives through. The attacker's input is not code that a program runs. It is natural-language content, such as a skill body, a manifest or a configuration value, that an agent reads and treats as an instruction or as context. Tools built to find the same weakness in code, such as SAST and secret scanners, do not read that channel, so the flaw stays invisible to them until the agent has acted on it. + +A record on this footing says that the mechanism is conventional, names the channel, and says what a code-oriented tool misses. This text is meant to be copied into each record's `vulnerability_rationale` and extended with the record's own point. + +It fits 00004, 00005 and 00033 in full. 00047 and 00075 use its second half (tools built for code do not look where the weakness sits) but each rests mainly on a stated argument of its own, given under the record. 00040 and 00073 rest on their own arguments and use the shared text only for the framing. + +## The records + +### AVE-2026-00004: Arbitrary code execution via shell pipe injection in agentic component + +> Component instructs the agent to pipe remote content into a shell interpreter (curl|bash, wget|sh, eval(requests.get(...))). + +- **Audit:** lines 679 to 717, classification E, decision JUSTIFY, confidence HIGH. +- **Weakness it names:** Command injection (CWE-78 territory; the record also cites CWE-77) delivered as `curl | bash` style directives in natural-language instructions. +- **The audit's agentic-specific distinction:** Stated in the record and held up by the audit: SAST finds command injection in code, not in natural-language instructions that produce the same effect once an agent follows them. The mechanism is conventional; the channel that evades conventional tooling is the agentic part. +- **Concrete or only asserted:** Concrete, and already in the record. +- **Decision:** JUSTIFY. The audit's Q6 answer cuts against novelty, but the record already names its real distinction, so it stays as a separate class and is not merged into generic CWE-78. The shared rationale applies in full. +- **Next step:** Add the shared rationale to `vulnerability_rationale`. The references are CWE-78, CWE-77, an OWASP Top 10 page and the record's own file, so a primary source has to be found (`find_primary_source`). +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-owasp-mcp.md`, `cfgaudit-to-ave.md`, `clawscan-to-ave.md`, `skillspector-to-ave.md`. + +### AVE-2026-00005: Recursive file system destruction via destructive command injection in agentic component + +> Component instructs the agent to execute recursive deletion commands on broad filesystem paths or system directories. + +- **Audit:** lines 718 to 752, classification E, decision JUSTIFY, confidence HIGH. +- **Weakness it names:** Destructive command patterns (`rm -rf /` class) in natural-language setup or cleanup instructions. +- **The audit's agentic-specific distinction:** The same natural-language-delivery argument as 00004, already stated. The audit also keeps it apart from 00004 because the impact differs: irrecoverable data loss with no code-execution requirement, a severity and detection distinction and not only a label. +- **Concrete or only asserted:** Concrete, inherited from 00004 with one added distinction. +- **Decision:** JUSTIFY. Structurally near-identical to 00004, which the audit flagged for a cross-record pass to confirm the two are worth keeping apart. The audit leaned yes on the impact difference, and so does this decision. If that pass later finds them redundant, the route is a merge into 00004, not a rejection. +- **Next step:** Shared rationale plus the impact distinction. A primary source is needed: the references are CWE-78, CWE-20, an OWASP LLM Top 10 project page and the record's own file. +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-owasp-mcp.md`, `cfgaudit-to-ave.md`, `clawscan-to-ave.md`, `skillspector-to-ave.md`. + +### AVE-2026-00033: Unsafe Deserialization or Eval Instruction + +> Component instructs the agent to deserialize untrusted data using insecure methods (pickle, yaml.load, eval) or to evaluate dynamic code strings received from external or user-controlled sources, enab (cut off at 200 characters in the record itself, see "Not in the audit" below) + +- **Audit:** lines 753 to 783, classification E, decision JUSTIFY, confidence HIGH. +- **Weakness it names:** Unsafe deserialization or eval (CWE-502 and CWE-94) instructed in natural language: `pickle.loads`, unguarded `yaml.load`, `eval` or `exec` on untrusted strings. +- **The audit's agentic-specific distinction:** The same argument and standard of evidence as 00004 and 00005; it is the third member of the family. +- **Concrete or only asserted:** Concrete, inherited. +- **Decision:** JUSTIFY. Consistent treatment with the family: it stays, on the same justification. +- **Next step:** Shared rationale. A primary source is needed: the references are CWE-502, CWE-94, an OWASP Top 10 page and the record's own file. +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-opencre-pilot-DRAFT.md`, `ave-to-opencre-pilot-mapping-READABLE.md`, `ave-to-owasp-mcp.md`, `clawscan-to-ave.md`, `skillspector-to-ave.md`. + +### AVE-2026-00035: Environment or Sensor Data Manipulation + +> Component instructs the agent to fabricate, alter, or suppress sensor readings, environment observations, or system state reports to deceive operators or downstream agents. + +- **Audit:** lines 118 to 161, classification E, decision JUSTIFY, confidence MEDIUM. +- **Weakness it names:** Telemetry and sensor integrity (CWE and ICS territory): no provenance or integrity check between a tool's real output and what is reported to a decision-maker. +- **The audit's agentic-specific distinction:** Real but not written down. The audit says the Q6 test cuts against the record as it stands, because a deterministic reporting pipeline with the same integrity gap has essentially the same vulnerability. What is agentic is narrower: a natural-language-driven relay can be told, in plain English, to misreport, without the hardware or firmware compromise that conventional telemetry spoofing needs. +- **Concrete or only asserted:** Real but unwritten: nothing in the record's text states it. +- **Decision:** JUSTIFY-IF-WRITTEN. It stays only if the record states that distinction and answers Q6 in its own words. As written it cannot be told apart from the generic telemetry-integrity class that CWE already covers. +- **Next step:** In its batch, write the instructable-fabrication distinction and the Q6 answer into `vulnerability_rationale`. If they cannot be written honestly, reject it. +- **Cited in crosswalks:** `ave-to-owasp-mcp.md`. + +### AVE-2026-00040: Insecure Output - Unescaped Injection into Downstream System + +> Component instructs the agent to produce output that will be directly interpreted by a downstream system (SQL database, HTML renderer, shell) without escaping or sanitisation, enabling classic injecti (cut off at 200 characters in the record itself, see "Not in the audit" below) + +- **Audit:** lines 1659 to 1669, classification E, decision JUSTIFY, confidence not stated (compact entry). +- **Weakness it names:** Classic injection (CWE-79, CWE-89, CWE-116 territory) through agent output passed unescaped to a downstream interpreter (SQL, HTML, shell). +- **The audit's agentic-specific distinction:** The audit's compact entry gives one line: the agentic amplification is the trust elevation that backend systems grant an agent compared with raw user input, which draws less scrutiny. +- **Concrete or only asserted:** Concrete in the audit's line, but a compact verdict is not a seven-question pass, and the record's own text (an instruction to produce output that is interpreted without escaping) does not say it. +- **Decision:** JUSTIFY. The trust-elevation point is a distinction a deterministic program does not have, and it is specific to an agent acting as a trusted intermediary. It stays. +- **Next step:** In its batch, write the full seven-question pass, put the trust-elevation distinction in `vulnerability_rationale`, and find a primary source: its references are CWE-79, CWE-116, an OWASP LLM Top 10 page and the record's own file. +- **Cited in crosswalks:** `ave-to-owasp-mcp.md`, `skillspector-to-ave.md`. + +### AVE-2026-00047: Hardcoded credentials in agent component - API keys and secrets exposed in skill files + +> Skill file contains a high-entropy string adjacent to a credential keyword such as api_key, secret, token, password, or a known key format prefix such as sk- or Bearer. The credential is a literal value, not an environment variable reference or secrets manager path. + +- **Audit:** lines 784 to 823, classification E, decision JUSTIFY, confidence HIGH. +- **Weakness it names:** Hardcoded secrets in source (CWE-798). +- **The audit's agentic-specific distinction:** Stated in the record and held up by the audit: a credential in a skill file sits in the same context window an LLM reads, so a prompt-injection payload elsewhere in that context can instruct the agent to read and exfiltrate it. A deterministic program reading the same file has no such boundary. +- **Concrete or only asserted:** Concrete, and already in the record. +- **Decision:** JUSTIFY. A conventional root cause with a real, stated amplification that a secrets-scanner finding would not capture. It stays, and it rests on this argument more than on the shared one. +- **Next step:** Add the amplification to `vulnerability_rationale`; the shared text supplies only the framing. It already has references beyond taxonomy pages. +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-opencre-pilot-DRAFT.md`, `ave-to-opencre-pilot-mapping-READABLE.md`, `ave-to-owasp-ai-exchange.md`, `ave-to-owasp-mcp.md`, `cfgaudit-to-ave.md`, `clawscan-to-ave.md`. + +### AVE-2026-00049: HTTP Host Header Injection via Agent-Initiated Request (BadHost) + +> Component sets or overwrites the HTTP Host header on outbound requests to a value that does not match the declared target endpoint's natural host. The injected host points to attacker infrastructure. Pattern also manifests as X-Forwarded-Host, X-Original-URL, or Forwarded header manipulation that causes server-side request routing to an unintended destination. + +- **Audit:** lines 824 to 867, classification E, decision JUSTIFY, confidence LOW. +- **Weakness it names:** HTTP Host-header attack, a well-documented web-security class (the audit cites PortSwigger's research). +- **The audit's agentic-specific distinction:** None stated. The audit calls it the weakest-justified record of its group. It names a plausible distinction that is not written down: an agent often builds request parameters, headers included, from content it has just processed, so an attacker-controlled header value is reachable through indirect prompt injection and does not need direct access to the client. +- **Concrete or only asserted:** Unwritten, plausible. +- **Decision:** DEFER. Without that argument the record reads as a port of a known web class, and the audit named merge or deprecate as the reasonable alternative. It is deferred, not rejected, so that the argument can be written if it holds. +- **Next step:** Deferred on 2026-10-31. Before the 2.0.0 release either the record states the injection-reachability argument, with evidence, or it is rejected. +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-owasp-mcp.md`, `clawscan-to-ave.md`, `skillspector-to-ave.md`. + +### AVE-2026-00052: Command injection via unsanitized tool-call parameter in MCP server implementation + +> MCP tool handler code passes a caller-supplied tool-call parameter value directly into a shell or system-command execution function without sanitization, executing arbitrary OS commands under the server process's privileges -- independent of any agent instruction or prompt content. + +- **Audit:** lines 868 to 912, classification E, decision JUSTIFY, confidence LOW. +- **Weakness it names:** OS command injection (CWE-78) in an MCP server's own tool handler. +- **The audit's agentic-specific distinction:** None at the mechanism level. The audit says it is not an agentic vulnerability in any behavioral sense, and the record itself says the attack is independent of any agent instruction or prompt content. The only argument is a coverage one: prompt-injection scanners, which dominate this space, cannot find it, because there is no instruction text to match. +- **Concrete or only asserted:** Asserted only, and as a coverage argument, not a mechanism. +- **Decision:** REJECT. The audit called this its hardest call and asked whether the coverage argument is enough for a distinct record, or whether the record belongs with general AppSec tooling that cross-references AVE. The decision is that it is not enough: swap the model for a deterministic program and the mechanism is unchanged, and CWE-78 names it. +- **Next step:** Rejected through the decision on #234; `rejection_reason` is that comment's URL. Its references (a ZDI advisory, an NVD entry and a Snyk advisory) stay on the record. +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-owasp-ai-exchange.md`, `ave-to-owasp-mcp.md`, `cfgaudit-to-ave.md`, `skillspector-to-ave.md`. SkillSpector's crosswalk notes it as pending deprecation and records no mapping; cfgaudit has it only in its gaps section. + +### AVE-2026-00053: Path traversal via unsanitized path parameter in MCP resource/file-handler implementation + +> MCP resource or file-handler tool's own path-validation code fails to canonicalize and contain a caller-supplied path or URL parameter, allowing directory-traversal sequences to read or write files and resources outside the tool's declared scope. + +- **Audit:** lines 1741 to 1752, classification E, decision JUSTIFY, confidence LOW. +- **Weakness it names:** Path traversal (CWE-22) in an MCP resource or file handler. +- **The audit's agentic-specific distinction:** None beyond the coverage argument. The audit's compact entry poses the same open question as for 00052 (coverage argument against genuine behavioral distinction) and gives the same verdict, JUSTIFY at low confidence. +- **Concrete or only asserted:** Asserted only. +- **Decision:** REJECT. The same class of mechanism as 00052, a caller-supplied value reaching a sensitive sink in the tool's own code independent of any agent instruction, and the same answer. +- **Next step:** Rejected with 00052 through #234. Its references (three NVD entries) stay on the record. +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-opencre-pilot-DRAFT.md`, `ave-to-opencre-pilot-mapping-READABLE.md`, `ave-to-owasp-ai-exchange.md`, `ave-to-owasp-mcp.md`, `cfgaudit-to-ave.md`. cfgaudit has it only in its gaps section. + +### AVE-2026-00054: Code-execution sandbox escape via JavaScript prototype-chain traversal + +> A code-execution tool's sandbox fails to contain a submitted payload that uses prototype-chain traversal to reach the host JavaScript or Python runtime, achieving code execution with host-level privileges outside the tool's declared execution boundary. + +- **Audit:** lines 913 to 952, classification E, decision JUSTIFY, confidence LOW. +- **Weakness it names:** Sandbox escape through JavaScript prototype-chain traversal, a pre-LLM, well-studied containment-failure class. +- **The audit's agentic-specific distinction:** Not strongly stated. The record separates itself from 00042 (how malicious code gets in) by scope (what happens once code is running) but does not argue why an agent-execution sandbox is more exposed than any other. The audit names a plausible angle that is not in the record: LLM-generated code can trigger prototype-chain patterns without adversarial intent more often than human-written code, widening the practical trigger surface. +- **Concrete or only asserted:** Unwritten, plausible. +- **Decision:** DEFER. The angle is statable but unevidenced. It is deferred so that it can be written, with evidence, or the record rejected. +- **Next step:** Deferred on 2026-10-31. Before the 2.0.0 release the record states the distinction or is rejected. +- **Cited in crosswalks:** `ave-to-ast10.md`, `ave-to-owasp-mcp.md`. + +### AVE-2026-00060: STDIO transport shell injection via unsanitized tool call parameters + +> Tool call parameters containing shell metacharacters (backticks, pipes, semicolons, command substitution syntax) are passed to a host shell without escaping or parameterization, resulting in execution of attacker-controlled shell commands rather than the parameter being treated as inert string data. + +- **Audit:** lines 1796 to 1808, classification E, decision JUSTIFY, confidence MEDIUM. +- **Weakness it names:** OS command injection (CWE-78) in shared MCP SDK STDIO transport code. +- **The audit's agentic-specific distinction:** A stronger argument than for 00052 and 00053, in the audit's words: the flaw lives in shared SDK code, so the blast radius spans every server built on an affected SDK. It remains a flaw independent of any agent instruction, and the audit gave only medium confidence. +- **Concrete or only asserted:** Stated, but it is an argument about reach, not about mechanism. +- **Decision:** REJECT. Reach is a severity argument. The mechanism test (swap the model for a deterministic program) gives the same flaw. 00060 is the strongest of the four rejections and the one most easily argued the other way, and the decision is to treat it with its two siblings, as #234 does. Its references are a vendor homepage, a CWE-78 page and its own file, so even on its merits it lacks a citable primary source. +- **Next step:** Rejected through #234. The record's credit (`researcher`) is part of the record and stays with it. +- **Cited in crosswalks:** `cfgaudit-to-ave.md`. cfgaudit has it only in its gaps section, where its note says the flaw needs analysis of the server's source and not a read of its launch configuration. + +### AVE-2026-00061: TLS certificate verification disabled in agent component configuration + +> Configuration explicitly sets a TLS verification bypass flag (verify=False, rejectUnauthorized: false, or equivalent) for the component's own outbound network calls, rather than relying on default, enforced certificate validation. + +- **Audit:** lines 953 to 991, classification E, decision DEPRECATE-OR-JUSTIFY, confidence LOW. +- **Weakness it names:** TLS certificate verification disabled in a component's configuration (CWE-295, an insecure-configuration weakness). +- **The audit's agentic-specific distinction:** None stated, and the audit found none obvious: it calls this the weakest agentic-distinction candidate it saw. It names a plausible one that the record does not state: a tampered response over an unverified connection often becomes direct agent context that the model acts on, where a traditional application might only render it for a human to judge. +- **Concrete or only asserted:** Absent from the record; the plausible argument is unwritten. +- **Decision:** REJECT. The audit recommended either writing that argument or treating this as a CWE-295 crosswalk entry, not a standalone record. The decision is the second. It is the closest call of the four, but the record states no mechanism that CWE-295 does not already cover. +- **Next step:** Rejected through #234, which pings cfgaudit's author first, because 00061 is the one of the four that a crosswalk maps. +- **Cited in crosswalks:** `ave-to-opencre-pilot-DRAFT.md`, `ave-to-opencre-pilot-mapping-READABLE.md`, `ave-to-owasp-ai-exchange.md`, `cfgaudit-to-ave.md`, `skillspector-to-ave.md`. cfgaudit maps CFG075 to it and emits the id. SkillSpector's crosswalk cites it in rows SC7, TM1 and TM3. + +### AVE-2026-00062: Unpinned dependency version allowing supply chain substitution + +> A component's declared dependency references a mutable version specifier (a floating tag, a version range with no upper bound, an unpinned package name with no hash or lockfile entry) rather than a specific, content-addressed or exact-version reference. + +- **Audit:** lines 992 to 1036, classification E, decision JUSTIFY-OR-MERGE, confidence LOW. +- **Weakness it names:** Unpinned dependency versions allowing supply-chain substitution (dependency-confusion territory). +- **The audit's agentic-specific distinction:** Not stated, and weaker than its neighbours 00074 (dead-anchor reclamation: the pin was correct when written) and 00066 (hallucinated-name squatting: the attack surface is the model's own hallucination), which cover the interesting edges. The audit's candidates are a merge into a broader agentic-supply-chain umbrella (with 00074, 00075, 00034 and 00066) or an explicit argument, such as agent-approved dependency changes moving faster and with less review than conventional ones. +- **Concrete or only asserted:** Unwritten, and weaker than its siblings. +- **Decision:** DEFER. The audit decision was JUSTIFY-OR-MERGE at low confidence. It is deferred so that the choice between an argument, a merge into an active record and a rejection is made once. +- **Next step:** Deferred on 2026-10-31. Before the 2.0.0 release it states the distinction, is merged (`merged_into` an active record) or is rejected. Its references are only taxonomy pages and its own file. +- **Cited in crosswalks:** `ave-to-maestro.md`, `cfgaudit-to-ave.md`, `skillspector-to-ave.md`. cfgaudit's crosswalk says this record closes the supply-chain pinning surface, so any outcome other than keeping it reaches cfgaudit. + +### AVE-2026-00072: MCP server bound to all network interfaces with no authentication step (NeighborJack) + +> An MCP server's declared args or env set its bind address to the wildcard 0.0.0.0 or [::] rather than a loopback address or an explicitly scoped, narrower interface, with no accompanying authentication requirement for incoming connections. + +- **Audit:** lines 1037 to 1077, classification E, decision JUSTIFY, confidence MEDIUM. +- **Weakness it names:** Binding a server to all network interfaces with no authentication (CWE-284 territory), documented as the pattern called NeighborJack. +- **The audit's agentic-specific distinction:** Better justified than 00061 and 00062, and prevalence-based: MCP servers commonly ship with no authentication on the assumption that only a local, already-trusted caller can reach them, an assumption that binding to 0.0.0.0 silently breaks. The audit calls it an ecosystem argument and not a mechanism one, but a real and citable one. +- **Concrete or only asserted:** Stated, and prevalence-based. +- **Decision:** JUSTIFY-IF-WRITTEN. It stays only if the record states the prevalence argument and answers Q6 in its own words: it should say that the design assumption, and not the misconfiguration alone, is what makes this an AVE class. +- **Next step:** In its batch, write the argument and the Q6 answer into `vulnerability_rationale`, or reject it. Its references are only taxonomy pages and its own file, so a primary source is needed (`find_primary_source`). +- **Cited in crosswalks:** `cfgaudit-to-ave.md`, `skillspector-to-ave.md`. + +### AVE-2026-00073: Telemetry or API endpoint redirect via static configuration value + +> A component's committed configuration sets a telemetry exporter endpoint, a model/provider base URL, an MCP server URL, an agent_card_url, or an equivalent traffic-destination value to a host other than the component's own declared or default provider, or to a host reachable only over cleartext http://, with no accompanying instruction text and no content injected into the model's context. + +- **Audit:** lines 1078 to 1117, classification E, decision JUSTIFY, confidence HIGH. +- **Weakness it names:** Configuration-based traffic redirection of endpoints specific to agentic systems: LLM provider base URLs, MCP server URLs and A2A agent-card URLs. +- **The audit's agentic-specific distinction:** Strong and well sourced: the record cites a real CVE (CVE-2026-21852) in which a redirected `ANTHROPIC_BASE_URL` leaked a user's API key, and the endpoint types exist only because the component is agentic. +- **Concrete or only asserted:** Concrete and cited. The audit calls it the best-justified record of its group. +- **Decision:** JUSTIFY. It stays as is. It rests on its own cited argument and not on the shared natural-language text. +- **Next step:** Add the argument to `vulnerability_rationale`, so that it is stated in the record and not only in the audit. +- **Cited in crosswalks:** `cfgaudit-to-ave.md`, `skillspector-to-ave.md`. + +### AVE-2026-00075: Bytecode poisoning: compiled .pyc cache diverges from its own reviewed .py source + +> A skill package contains a .pyc (or .pyo) file whose disassembled bytecode references dangerous primitives (os.system, subprocess, eval, exec, socket, urlopen, credential file paths such as .aws/credentials or .ssh/id_) that do not appear anywhere in its sibling .py source's own text, meaning the compiled artifact the interpreter will actually load and execute contains capability its reviewed source does not show. + +- **Audit:** lines 1118 to 1166, classification E, decision JUSTIFY, confidence HIGH. +- **Weakness it names:** Bytecode poisoning: the interpreter prefers a compiled `.pyc` that diverges from its reviewed `.py` source (a general interpreter property, not agent-specific in mechanism). +- **The audit's agentic-specific distinction:** Strong and well sourced: the record frames it, citing research from the CSA AI Safety Initiative and Trail of Bits, as a technique for evading agent-skill scanners specifically, which document their own inability to analyze binary or encrypted code. It is already differentiated from 00057. +- **Concrete or only asserted:** Concrete and cited. +- **Decision:** JUSTIFY. It stays as is.

Records being rejected do not carry it | + +**Batches.** Ten records per batch, in this order: the 64 records that need no decision (batches 1 to 7, in id order), the seven JUSTIFY records (batches 7 to 8), the two JUSTIFY-if-written records (batch 8), 00081 to 00089 (batches 8 to 9), then the three deferred records (batch 9, waiting for their deadline) and last the four rejected ones (batch 9, waiting until the decision on #234 is a week old). The last batch is therefore the one that cannot be done early. + +**Primary sources.** Twenty-two records have references that are only taxonomy pages, homepages or links back to AVE: 00003, 00004, 00005, 00006, 00012, 00013, 00014, 00017, 00022, 00024, 00026, 00030, 00032, 00033, 00034, 00039, 00040, 00060, 00061, 00062, 00071, 00072. 00060 and 00061 are among them and are being rejected, so they carry no `find_primary_source`; the other twenty do. The list is computed from the references by the rule in the table, so it can be recomputed. + +**Not in the audit: truncated fingerprints.** Eight records have a `behavioral_fingerprint` that stops mid-word at exactly 200 characters: 00023, 00026, 00029, 00030, 00033, 00038, 00039, 00040. The schema sets no length limit, and the pre-migration versions of the same records are complete sentences of 104 to 158 characters, so the cut first appears in the AIVSS migration commits of 2026-05-12 and 2026-05-13 (#17 and #18), which replaced each short sentence with a longer one that was stored cut at 200 characters. The history holds only those two versions of each record, the short original and the cut one, so the complete longer text was never committed. Restoring a fingerprint, to the original sentence or to a newly written one, is a content change that needs the maintainer's approval, like the other fingerprint actions. 00033 and 00040 are among the sixteen generic-class records. + +**Not in the queue.** `credit_correction`: the researcher-credit audit (`docs/audits/researcher-credit-audit.json`) is not in the repository yet, so no entry carries it. Score changes: none planned. Rewording a fingerprint or changing a score is a content change; each needs the maintainer's approval first. + +## For the rejection pull request + +- `rejection_reason` is the URL of the decision comment on #234, once it is posted; it is not known before then. +- cfgaudit maps CFG075 to AVE-2026-00061 (`cfgaudit-to-ave.md`, and `avemap.go` in cfgaudit), and emits that id in its JSON and SARIF output, so rejecting 00061 changes cfgaudit's output. Its author is asked on #234 how to handle the row. The crosswalk is theirs to change, and it is not changed before they answer. +- cfgaudit's crosswalk also says AVE-2026-00062 closes the supply-chain pinning surface, so a decision on 00062 reaches it too. +- `skillspector-to-ave.md` cites 00061 in rows SC7, TM1 and TM3, and 00052 in notes (TT5, AST4) that already say it is pending deprecation and record no mapping; the pull request moves those rows. +- Other crosswalk files that cite the four are listed under each record above. diff --git a/docs/decisions/quality-queue.json b/docs/decisions/quality-queue.json new file mode 100644 index

Also stated what `taxonomies[].version`, `releaseDateUtc` and `downloadUri` hold, which this document had left unspecified: that same release's version, date and `ave-records.json`. Both examples moved from `1.1.0` to the `v1.2.0` release. The run properties are optional and no existing field was removed or changed, so the version stays v1.0. **Revision note (2026-10-31):** added form B, a second way to carry the AVE id (a tool's own `ruleId`, with `properties.ave_id` on the rule and on each result), because a tool that emits AVE ids in SARIF today does exactly that. Form A is unchanged. No field changed meaning and every output that was conformant still is, so this is a minor version, v1.1, not a major one; a consumer that read only `result.ruleId` must now also read `properties.ave_id` to see form B's ids.

The embedded AVE taxonomy gains a `guid` (`5110b285-34d7-5334-94db-0308b24cfb49`), a canonical generated file (`dist/ave-taxonomy-latest.json`, built by `scripts/build_taxonomy.py`, with a subset mode for scanners) and the rule that a taxonomy is identified by that guid. The checker gained form C extraction and six checks: `taxonomy_guid_missing`, `taxonomy_guid_mismatch`, `taxon_unknown`, `taxon_name_differs`, `reference_guid_mismatch` and `supported_taxonomies_missing`. Forms A and B are unchanged and every output that was conformant still is, with a `taxonomy_guid_missing` warning if it embeds an AVE taxonomy without a guid. A consumer that read only `result.ruleId` and `properties.ave_id` must now also read `rules[].relationships` and `result.taxa` to see form C's ids.
