OpenTelemetry's Zipkin remote endpoint cache could grow without bounds and increase memory pressure

CVE-2026-41310 [MEDIUM] CWE-400 OpenTelemetry's Zipkin remote endpoint cache could grow without bounds and increase memory pressure
OpenTelemetry's Zipkin remote endpoint cache could grow without bounds and increase memory pressure
### 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.
