Description OSIDB Bzimport 2026-08-25 22:42:13 UTC

Spring Security's DPoPProofJwtDecoderFactory contains a cache-based replay attack vulnerability. The internal cache storing JWT ID claims has a strict size limit, allowing attackers to evict legitimate entries by flooding the server with dummy requests, then replay intercepted valid DPoP proofs.
Spring Security 7.1.0
Spring Security 7.0.0 - 7.0.6
