Detailsinfo

A vulnerability was found in open-telemetry opentelemetry-java, opentelemetry-api and opentelemetry-extension-trace-propagators up to 1.61.x. It has been rated as problematic. Affected by this issue is an unknown code block. The manipulation with an unknown input leads to a allocation of resources vulnerability. Using CWE to declare the problem leads to CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. Impacted is availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-45292 since 05/11/2026. The exploitation is known to be easy. The attack may be launched remotely.
