OpenTelemetry JavaScript is the OpenTelemetry JavaScript client. Prior to 2.9.0, @opentelemetry/propagator-jaeger decodes incoming uber-trace-id and uberctx-* HTTP header values with decodeURIComponent() without handling decode errors, allowing an unauthenticated remote attacker to send a malformed percent-encoded value that throws an uncaught URIError and terminates a Node.js process using JaegerPropagator as the active propagator. This issue is fixed in version 2.9.0.

GHSA-45rx-2jwx-cxfr — OpenTelemetry JavaScript: Denial of service in `JaegerPropagator` via unhandled exception on a malformed header

Affected: npm: @opentelemetry/propagator-jaeger

## Summary

`@opentelemetry/propagator-jaeger` decodes incoming HTTP header values with `decodeURIComponent()` without handling decode errors. A single request carrying a malformed percent-encoded value (for example a bare `%`) in an `uber-trace-id` or `uberctx-*` header throws an uncaught `URIError`, terminating any Node.js process that uses `JaegerPropagator` as its active propagator.

## Impact

**Denial of Service:** Any unauthenticated remote attacker who can send an HTTP request to a service that has `JaegerPropagator` registered as the global propagator (e.g. via `OTEL_PROPAGATORS=jaeger` or `propagation.setGlobalPropagator(new JaegerPropagator())`) can terminate the process with a single request. Confidentiality and integrity are not affected.

## Am I affected?

This issue affects only a specific, opt-in configuration. If you use OpenTelemetry's default propagators (W3C TraceContext and Baggage), you are **not** affected.

You are affected only if you have registered `JaegerPropagator` as the active propagator. Check for:

- `@opentelemetry/propagator-jaeger` in your dependency tree, **and** - `OTEL_PROPAGATORS` set to `jaeger` (Jaeger only), **or** a direct `propagation.setGlobalPropagator(new JaegerPropagator())` call in your code.

Note: if `JaegerPropagator` is combined with other propagators through a `CompositePropagator` (for example `OTEL_PROPAGATORS=jaeger,tracecontext`), the process does not terminate - the composite propagator catches the error…
