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.

Affected versions:
Spring Retry 2.0.0 through 2.0.12; 1.3.0 through 1.3.4.
