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
CVE-2026-45292 affects the Java implementation of OpenTelemetry's API and SDK, specifically the baggage propagation feature. When processing oversized baggage, the affected versions allocate memory and consume CPU resources without limits, leading to a denial of service condition. The vulnerability can be exploited remotely by sending maliciously large baggage data, and due to automatic re-injection of baggage into outgoing requests, the denial of service effect can cascade to downstream services. The issue is tracked under CWE-770 (Allocation of Resources Without Limits or Throttling) and has been addressed in opentelemetry-java version 1.62.0.
Potential Impact
The vulnerability allows a remote attacker to cause unbounded memory allocation and high CPU consumption in affected services, resulting in denial of service. The automatic re-injection of baggage into outgoing requests means the impact can extend beyond the initially targeted service to downstream services, potentially amplifying the denial of service effect. There is no impact on confidentiality or integrity, only availability is affected.
Mitigation Recommendations
An official fix is available in opentelemetry-java version 1.62.0. Users should upgrade to version 1.62.0 or later to remediate this vulnerability. No additional mitigations are specified in the vendor advisory. Since this is not a cloud service, remediation is the responsibility of the user.
