Mitigation checklist
Recommended fix / mitigation
- Administrators can mitigate this issue by not configuring JaegerPropagator as the active OpenTelemetry propagator (use W3C Trace Context or B3 propagation instead), or by deploying an ingress/proxy in front of the affected service that validates or strips uber-trace-id and uberctx-* headers before they reach the application. Upgrading to @opentelemetry/propagator-jaeger >= 2.9.0 resolves the issue upstream.
