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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-400"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-94449","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537502","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"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.","remediation":"Update to a patched version of SmallRye Fault Tolerance or remove unused annotations to prevent memory leaks.","tags":["memory-leak","microservices","quarkus"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:12:28.315Z"}}
