7.5 HIGH

Published 2026-09-21 · Updated 2026-09-21

AI risk analysis

Summary: The flaw in SmallRye Fault Tolerance library causes a memory leak when using ApplyGuard or ApplyFaultTolerance annotations, leading to potential application crashes due to increased memory usage.
Exploitability: Exploitation requires the use of specific annotations and is moderately difficult as it involves understanding the internal workings of the library.
Blast radius: If exploited, this could result in service disruptions affecting microservices relying on Quarkus applications.
Prioritized remediation: Update to a patched version of SmallRye Fault Tolerance or remove unused annotations to prevent memory leaks.

NVD description

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.
