Summary
A vulnerability in the baggage propagation implementation in opentelemetry-java before version 1.62.0 causes unbounded memory allocation and CPU consumption when parsing oversized baggage. Since baggage is automatically re-injected into every outgoing request, the effect can fan out to downstream services that never received the original malicious request.
Risk Assessment
An attacker can send a malicious request with excessively large baggage, leading to resource exhaustion (memory and CPU) in the target service and subsequent services processing that baggage, potentially causing a denial of service (DoS) across the entire infrastructure.
Recommendation
Immediately update the opentelemetry-java library to version 1.62.0 or later, which contains the fix for this vulnerability.
Original NVD description (English source)
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.
