CVE-2026-41710 Spring CVE debrief

CVE-2026-41710 is a medium-severity vulnerability affecting Spring Retry versions 2.0.0 through 2.0.12 and 1.3.0 through 1.3.4. An attacker can craft a large number of unique requests that trigger a failure, exhausting the capacity of the application-wide stateful retry cache. Once the cache is full, it permanently rejects any further updates, causing all later stateful retries and circuit breakers in the application to fail.
