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.\n\n\n## Impact\n\n**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.\n\n## Am I affected?\n\nThis issue affects only a specific, opt-in configuration. If you use OpenTelemetry's default propagators (W3C TraceContext and Baggage), you are **not** affected.          \n\nYou are affected only if you have registered `JaegerPropagator` as the active propagator. Check for:\n\n- `@opentelemetry/propagator-jaeger` in your dependency tree, **and**\n- `OTEL_PROPAGATORS` set to `jaeger` (Jaeger only), **or** a direct `propagation.setGlobalPropagator(new JaegerPropagator())` call in your code.\n\nNote: 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 - but affected requests silently fail to extract context. You should still upgrade.\n\n\n## Patched versions\n\n- `@opentelemetry/propagator-jaeger` 2.9.0\n\n## Remediation\n\nUpdate `@opentelemetry/propagator-jaeger` to 2.9.0 or later. The propagator now ignores header values it cannot decode instead of throwing.\n\n**Interim mitigation (if you cannot update):** Trace-context headers should never be accepted unfiltered from untrusted callers. Until you can upgrade, strip or validate the `uber-trace-id` and `uberctx-*` headers on inbound requests at your edge - for example with a reverse proxy, API gateway, or load balancer (nginx, Envoy, etc.) - so that only trusted upstream services can set them.\n\n## Details\n\n`JaegerPropagator.extract()` calls `decodeURIComponent()` on raw header values at two unguarded call sites: the `uber-trace-id` trace header and each `uberctx-*` baggage value. `decodeURIComponent()` throws `URIError: URI malformed` on invalid percent-encoding. Because the HTTP instrumentation extracts context before its request-handler error wrapper, and a single configured propagator is not wrapped in a `CompositePropagator` (which would otherwise catch the error), the exception propagates as an `uncaughtException` and terminates the process.\n\n## Proof of concept\n\nAgainst a service using `JaegerPropagator`:\n\n```bash\ncurl -H 'uberctx-user: %' http://target/\n# or\ncurl -H 'uber-trace-id: %' http://target/\n```\n\nThe Node.js process exits with `URIError: URI malformed` and subsequent requests are refused.","state":0,"publishedAt":"2026-07-21T19:07:28+00:00","modifiedAt":"2026-09-10T03:50:51.3382203+00:00","affected":[{"ecosystem":"npm","name":"@opentelemetry/propagator-jaeger","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.9.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/open-telemetry/opentelemetry-js/security/advisories/GHSA-45rx-2jwx-cxfr","https://nvd.nist.gov/vuln/detail/CVE-2026-59892","https://github.com/open-telemetry/opentelemetry-js/commit/b1c196d49d54caae59741cca0a9d57d101d7ea88","https://github.com/open-telemetry/opentelemetry-js","https://github.com/open-telemetry/opentelemetry-js/releases/tag/v2.9.0"],"sourceUrl":"https://github.com/advisories/GHSA-45rx-2jwx-cxfr","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-45rx-2jwx-cxfr","identifiers":["GHSA-45rx-2jwx-cxfr","CVE-2026-59892"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
