prior to 7.1.0.1. It is, therefore, affected by a vulnerability:

  - Spring Security's DPoPProofJwtDecoderFactory uses an internal cache to store the processed jti (JWT ID) claims,
    which is intended to protect against replay attacks by ensuring that each DPoP proof is only used once. However,
    this cache has a strict maximum size limit of entries. If the attacker is able to intercept a legitimate user's
    valid DPoP proof, they can flood the server with dummy requests to forcefully evict the legitimate jti from the
    cache. Once the jti is evicted, the attacker can successfully replay the intercepted valid DPoP proof, leading to
    unauthorized access and impersonation of the victim. (CVE-2026-41707)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
