Summary

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. Successful exploitation of this flaw can terminate a Node.js process, resulting in a Denial of Service (DoS).

This flaw affects the @opentelemetry/propagator-jaeger package used by container images that configure the Jaeger trace-context propagator. Red Hat CVSS score (7.5, Important) is consistent with upstream and NVD scoring.

Weakness: CWE-248. Affected Red Hat products: Red Hat Developer Hub 1.10; Red Hat Developer Hub 1.9; Self-service automation portal 2.

Red Hat lists OpenShift Serverless as not affected. Red Hat fixing advisory: RHSA-2026:49642, RHSA-2026:52768.

Is CVE-2026-59892 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-59892 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.

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.
