NVD Description

Note: Versions mentioned in the description apply only to the upstream langfuse-2 package and not the langfuse-2 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
