49th percentile - higher than 49% of all known CVEs

Summary

A flaw was found in the SmallRye Fault Tolerance library, which is used by Quarkus to provide strategies like retries and circuit breakers for microservices. The issue occurs when using the ApplyGuard or ApplyFaultTolerance annotations, where the library fails to release internal tracking objects after each request. This causes a steady increase in memory usage that eventually leads to the application slowing down and crashing due to lack of memory.

Risk Assessment

Long-running Quarkus applications may gradually consume more memory until they crash due to memory exhaustion, causing service unavailability. The risk is high for production systems using these annotations.

Recommendation

Upgrade SmallRye Fault Tolerance (and Quarkus) to a version containing the fix for releasing tracking objects. Monitor application memory usage and consider restarting services as a temporary workaround.
