CVE-2026-59892 · OpenTelemetry JavaScript: Denial of service in `JaegerPropagator` via unhandled exception on a malformed header
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
