GHSA-ch52-4w7c-c8xp: http-cache-semantics <= 4.2.0 fails to validate security-zeroed cache entries when processing client max-stale directives, allowing cross-user cached-response disclosure in shared caches. 4.3.0 (npm latest, released 2026-10-04) restructures the max-stale evaluation path and is covered by its 128-test upstream suite. Impact-verified for this repo: the only consumer chain is electron-builder -> app-builder-lib -> @electron/get -> got -> cacheable-request (dev tooling). @electron/get 3.x downloads via native fetch, and got only routes through cacheable-request when a cache option is passed (nothing in this tree passes one), so the vulnerable code was never on any active request path. A/B request comparison shows byte-identical outgoing requests across both versions.
对全部测试代码做了一轮审计（electron / server / src），修复 15 处问题： 失效或无效断言： - pluginManager: symlink 平台限制改用 t.skip，安全断言不再静默跳过 - pluginPageBridge: 边界用例改为恰好 160k 字符，真正覆盖 MAX_AI_USER_CHARS - xTweetAuthPersistence: migrate 前置条件缺失时测试显式失败（CWE-922 回归网） - webdavService: 删除从不传递的 AbortController 与恒真断言 - autoSync.repoHash: 删除与自身比较的恒真断言 - categoryLanguage: fixture 更新分支删除无意义断言 - abortUtils: 用 vi.getTimerCount() 断言定时器确被清理 - routes(mcp): 删除 typeof boolean 恒真用例，说明改为注释 不稳定与状态泄漏： - parity(mcp): beforeEach 复位 getVectorAvailability，消除用例顺序依赖 - autoSync.repoHash: two-pull describe 补 resetSyncHashes 与 store 状态恢复 - aiRequestLimiter: RPM 窗口放宽到 2s，探测 200ms，消除事件循环卡顿竞态 - ReleaseCard: 外层 beforeEach 复位模块级 store 语言，en 不再泄漏 - MarkdownRenderer: 数学门控改为直接断言导出的 MATH_PATTERN， 移除 50ms 真实定时器竞态与 cwd 相关的整文件文本扫描 - pluginMarketplace: chmod 000 用 try/finally 恢复；afterEach 清理临时目录 - RepositoryReleaseSheet: 修复注释中的损坏 UTF-8 字节

- Line 652: After calling t.skip() in the symlink-creation failure catch block,
return immediately so the test callback does not continue to plugin installation
or assertions. Locate the catch block using the t.skip call that reports
“Symlink creation unavailable.”
Review comments at @src/components/MarkdownRenderer.test.tsx:
- Line 696: Update the assertion on MATH_PATTERN.source to reject both positive
and negative lookbehind syntax, so the Safari compatibility test fails if either
form is introduced.

712-715: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win增加对纯文本动态加载路径的断言。
当前断言只检查正则结果，不检查渲染器是否调用数学插件的动态导入。若 effect 不再执行正则门控，这些测试仍可能通过。请渲染普通文本，并断言数学插件加载器未调用；同时保留对
.katex节点不存在的断言，以覆盖渲染结果。🤖 Prompt for AI Agents

timeoutMs 同时约束 Worker 启动与调用超时，真实 Worker 在高负载 CI 上 启动可能超过 50ms，导致 activate() 阶段直接抛 PLUGIN_RUNTIME_TIMEOUT。 提升到 2000ms 与同文件其他用例一致，被测的调用超时行为不变。 🤖 Generated with [Z.ai Code](https://chat.z.ai)
CodeRabbit nitpick：仅断言 MATH_PATTERN 门控结果，无法发现 effect 绕过 门控直接 import 的回归。补充 passthrough 加载计数器（vi.hoisted + vi.mock），普通文档用例排空微任务后断言加载器零调用、无 .katex 节点； 用例置于 display 用例之前并注明顺序约束（vitest 缓存已解析的 mock 模块）。 🤖 Generated with [Z.ai Code](https://chat.z.ai)

背景
修复 Dependabot 告警 #59（GHSA-ch52-4w7c-c8xp / CVE-2026-93748，High 7.5）：
http-cache-semantics <= 4.2.0在处理客户端max-stale指令时未校验出于安全考虑清零的缓存条目，共享缓存场景下可跨用户泄露缓存响应（含 Set-Cookie 会话凭据）。同时对全仓测试代码做了一轮审计并修复发现的问题。变更
1. 依赖修复（b69dac8）
http-cache-semantics4.2.0 → 4.3.0（npmlatest，2026-10-04 发布，上游 issue ci: add Docker Hub auto-publish workflow on v-tag push #56 已确认修复；仅锁文件 3 行变更）2. 升级影响验证（应用户要求重点测试）
electron-builder → app-builder-lib → @electron/get → got → cacheable-request（纯构建期工具链，不进产物、不在 server/worker 运行时）@electron/get@3.x已改用原生 fetch 下载；got 仅在显式传cache选项时才执行 cacheable-request（got/dist/source/core/index.js:1088），而全树无任何调用方传该选项 —— 漏洞代码在本仓从未处于活跃执行路径。对 got 实际调用方式做 A/B 对比：两版对外请求方法、HTTP 版本、全部头（含顺序）字节级一致npm audit中 http-cache-semantics 已清除3. 测试审计修复（f77e77c，15 处：0 high / 2 medium / 13 low）
t.skip（原安全断言在无符号链接权限平台静默跳过）；160k 字符边界用例真正触达MAX_AI_USER_CHARS；migrate缺失时显式失败（CWE-922 回归网）；删除 4 处恒真断言与死代码resetSyncHashes与 store 状态恢复；RPM 限流窗口放宽消除事件循环竞态；ReleaseCard 模块级 store 语言复位；MarkdownRenderer 数学门控改为直接断言导出的MATH_PATTERN（移除 50ms 真实定时器竞态与 cwd 依赖）；chmod 000 用 try/finally 恢复；补 marketplace 临时目录清理；修复 1 个文件的损坏 UTF-8 字节MATH_PATTERN供测试做确定性门控断言（export一处，无行为变化）验证
