Unbounded Memory Allocation via Baggage Prop in OpenTelemetry Java <1.62.0
CVE-2026-45292 Published on May 28, 2026

opentelemetry-java: Unbounded Memory Allocation in W3C Baggage Propagation
opentelemetry-java is the Java implementation of the OpenTelemetry API for recording telemetry, and SDK for managing telemetry recorded by the API. Prior to 1.62.0, a vulnerability affects the baggage propagation implementation in opentelemetry-api and opentelemetry-extension-trace-propagators. Parsing oversized baggage causes unbounded memory allocation and CPU consumption. Because baggage is automatically re-injected into every outgoing request, the effect can fan out to downstream services that never received the original malicious request. This vulnerability is fixed in 1.62.0.
