Summary

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.

Patch / fix

  • maven org.springframework.retry:spring-retry 2.0.13
  • Spring Spring Retry 1.3.5, 2.0.12.1
