CVE-2026-41707
Spring Security DPoPProofJwtDecoderFactory vulnerable to DPoP Proof Replay
Authentication Bypass by Capture-replay vulnerability in Spring Spring Security allows 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.
This issue affects Spring Security: 7.1.0, from 7.0.0 through 7.0.6, and from 6.5.0 through 6.5.11.
