Sensitive Data Exposure (CWE-525): Use of Web Browser Cache Containing Sensitive Information

Reachability: External · Exploitability: Moderate

Prevent cache reuse of tenant-specific proxy responses.

_upstream_response returns a new Response or JSONResponse, and the application middleware does not add cache directives. Add Cache-Control: no-store to both branches. Do not rely on private for tenant isolation.

Add narrow type hints to _run_with_otel_parent.

backend/pyproject.toml enables strict mypy checks, and this untyped helper violates the repository’s typing contract. Annotate task_instance as Task and use Callable[[], T] with a TypeVar for the callback and return value.

"""Attach extracted parent context and execute function.

When Celery auto-instrumentation is active, there is already a current
`run/...` span. Re-attaching extracted parent context here would make
service spans become siblings of `run/...` instead of children.

We only attach extracted context as a fallback when no active span exists.
"""Attach the extracted parent context and execute `fn` under it.

opentelemetry-instrumentation-celery's own extraction (CeleryGetter)
reads headers via getattr(task.request, key), but propagation headers
live in task.request.headers — so it never finds them and its `run/...`
span is always an unparented root. We extract from `.headers` ourselves
(see _extract_parent_context) and attach that as current before running
the task body, so spans created inside `fn` correctly nest under the
enqueueing request's trace instead of starting a disconnected one.

OpenTelemetry Python CeleryInstrumentor task span current context before task run implementation

💡 Result:

The OpenTelemetry Python CeleryInstrumentor manages the context of a task execution primarily through the Celery task_prerun and task_postrun signals [1][2]. The implementation details of how the current context is handled before the task runs are as follows: 1. Signal Connection: During instrumentation, the CeleryInstrumentor connects its _trace_prerun method to the Celery task_prerun signal [1][2]. 2. Context Extraction: When a task execution begins, _trace_prerun is triggered. It retrieves the task request attributes and uses an OpenTelemetry propagator (e.g., W3C TraceContext) to extract the parent trace context from the message headers via a celery_getter [1][3]. 3. Span Creation and Activation: - If a valid parent context is extracted, the tracer starts a new span as a child of that context (by default) or, if configured with use_span_links=True, creates a link to the parent span [4][3]. - The span is then activated using trace.use_span(span, end_on_exit=True), which makes it the current span in the execution context [1][3]. 4. Context Attachment: The instrumentor uses a utility helper (utils.attach_context) to store the active span, the context activation, and the token in a dictionary keyed by the task ID on the task instance itself [1][5]. This ensures that the state can be retrieved later during the task_postrun signal to correctly close the span [1][5]. By the time the actual task function body begins execution, the OpenTelemetry context has already been properly set, allowing functions like trace.get_current_span to return the correct worker span [6].

opentelemetry-instrumentation-celery 0.62b0 source CeleryGetter _trace_prerun task.request.headers

💡 Result:

In opentelemetry-instrumentation-celery version 0.62b0, the CeleryGetter class is responsible for retrieving OpenTelemetry context from the Celery request object during the _trace_prerun signal handler [1][2]. The _trace_prerun method is connected to the task_prerun signal and executes when a Celery worker starts a task [2][3]. Inside this handler, the instrumentation uses the extract function from the OpenTelemetry propagation API, passing the Celery task request object as the carrier and the celery_getter instance to retrieve distributed tracing context (such as W3C TraceContext) injected into the task headers by the producer [1][2][4]. The CeleryGetter.get method implementation retrieves values from the carrier (the task request) using getattr(carrier, key, None) [2][3]. A known technical issue (Issue #4359) in versions around 0.61b0-0.62b0 involves Celery's request context object containing non-string attributes (e.g., integers like timelimit), which can cause crashes in the propagator because the TextMapPropagator contract expects string values [5]. While CeleryGetter is intended to facilitate the extraction of headers, this discrepancy between Celery's request object structure and the expectation of the propagation API can lead to runtime errors when the propagator attempts to process these non-string attributes [5].

Preserve the active Celery task span.

setup_telemetry() activates CeleryInstrumentor before the task body runs. When _run_with_otel_parent() attaches parent_ctx, it replaces the current Celery task-span context while fn executes. Spans created by fn can therefore leave the Celery task span and create a disconnected trace subtree. Extract the parent context before Celery creates its task span, or pass it when creating that span. Add regression tests for valid task spans and valid headers.

_run_with_otel_parent to preserve the active Celery task span while applying the
extracted parent context, ensuring spans created by fn remain children of the
task span. Capture the external parent context before Celery creates its task
span or supply it during task-span creation, and add regression coverage for
valid task-span and valid-header scenarios.

Sentry Python 2.20.0 SentryPropagator OpenTelemetry propagator sentry-trace baggage traceparent

💡 Result:

In the Sentry Python SDK, the SentryPropagator is a component designed to bridge Sentry's native distributed tracing mechanisms with OpenTelemetry (OTel) [1][2]. It enables interoperability by handling the propagation of Sentry's specific tracing headers—sentry-trace and baggage—within an OpenTelemetry environment [1][2]. Key details regarding its functionality and use as of version 2.20.0: 1. Functionality: The SentryPropagator implements the OpenTelemetry TextMapPropagator interface [1][2]. - Extraction: It reads incoming sentry-trace and baggage headers from the carrier (e.g., HTTP headers) and populates the OpenTelemetry context [1]. This ensures that traces originating from other Sentry-instrumented services are correctly continued within the OTel-instrumented service [2]. - Injection: It takes the current span from the OpenTelemetry context and injects the corresponding sentry-trace and baggage headers into the outgoing request, allowing the trace to continue in downstream services [1]. 2. Usage context: - Sentry now recommends using the OTLPIntegration for most use cases, as it simplifies the ingestion of OpenTelemetry traces into Sentry by automatically configuring the exporter and required event linking [3][4]. - When using the OTLPIntegration, a SentryPropagator is often set up automatically to maintain compatibility with services using Sentry's native tracing [3][5]. - Note: The automatic setup of the SentryPropagator by the OTLP integration is deprecated and slated for removal in future major versions [3][5]. Users will be expected to configure propagation manually using the standard OpenTelemetry propagation API to avoid conflicts with other configured propagators [3][5]. 3. Relation to Traceparent: - While SentryPropagator handles sentry-trace and baggage, cross-service propagation is also supported via the standard W3C traceparent header [3][6]. Enabling propagateTraceparent in the Sentry SDK configuration allows the SDK to send the W3C traceparent header on outgoing requests, which ensures compatibility with OTel-only services [7][6]. For manual setup in an OpenTelemetry environment, you would typically add the SentryPropagator to your OpenTelemetry global text map propagator configuration [8][9]. top_results: [1][3][2][4][5]

Preserve W3C propagation at instrumented boundaries.

If any HTTP or Celery boundary uses W3C-only propagation, SentryPropagator() injects and extracts only sentry-trace and baggage, so that boundary can lose parent context. Configure a composite propagator that accepts and emits both Sentry and W3C formats.

In `@backend/app/core/telemetry.py` at line 203, Update the propagator
configuration around set_global_textmap and SentryPropagator to use a composite
propagator that injects and extracts both Sentry and W3C formats, preserving
parent context at HTTP and Celery boundaries.
