GHSA-88hf-wf7h-7w4mMediumCVSS 5.3
OpenTelemetry's Zipkin remote endpoint cache could grow without bounds and increase memory pressure
🔗 CVE IDs covered (1)
📋 Description
Summary
The Zipkin exporter remote endpoint cache accepted unbounded key growth derived from span attributes. In high-cardinality scenarios, this could increase process memory usage over time and degrade availability.
Details
- Introduce a bounded, thread-safe LRU cache for remote endpoints.
- Enforce fixed maximum size to prevent unbounded growth.
Impact
- A process using Zipkin export for client/producer spans could experience avoidable memory growth under sustained unique remote endpoint values.
