CVE-2026-45292: CWE-770: Allocation of Resources Without Limits or Throttling in open-telemetry opentelemetry-java
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.
AI Analysis
Technical Summary
The vulnerability CVE-2026-45292 affects opentelemetry-java versions before 1.62.0. It involves the baggage propagation feature in the opentelemetry-api and opentelemetry-extension-trace-propagators modules. When oversized baggage is parsed, it triggers unbounded memory allocation and CPU usage, potentially causing denial of service. Because baggage is automatically re-injected into every outgoing request, the impact can propagate to downstream services that did not receive the original malicious request. The issue is resolved in version 1.62.0.
Potential Impact
This vulnerability can cause denial of service due to excessive memory and CPU consumption when processing oversized baggage in telemetry data. The effect can cascade to downstream services because the baggage is re-injected into outgoing requests, potentially amplifying the denial of service impact beyond the initially targeted service. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
A fix is available in opentelemetry-java version 1.62.0. Users should upgrade to version 1.62.0 or later to remediate this vulnerability. Patch status is confirmed by the vendor advisory. No additional mitigations are specified in the advisory.
