CVE-2026-45292

MEDIUM CVSS 3.1: 5.3 EPSS 1.10%
Updated Sep 10, 2026
Java
Parameter Value
CVSS 5.3 (MEDIUM)
Fixed In 1.62.0
Type CWE-770 (Allocation Without Limits)
Vendor Java
Public PoC No

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.
