TL;DR

spring-security-oauth2-jose stores processed DPoP proof jti values in a bounded cache to prevent replay. An attacker who intercepts a valid proof can flood the server with dummy requests until the legitimate jti is evicted. After eviction, the intercepted proof can be replayed, impersonating the victim. The patch keeps replay protection effective when the cache is under pressure.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and you use DPoPProofJwtDecoderFactory for DPoP proof validation.
