Spring Security 6.5.x < 6.5.12 / 7.0.x < 7.0.6.1 / 7.1.x < 7.1.0.1 DPoP Proof Replay

Synopsis

The Spring Security install on the remote host is affected by an authentication bypass vulnerability.

Description

The version of Spring Security installed on the remote host is 6.5.x prior to 6.5.12, 7.0.x prior to 7.0.6.1, or 7.1.x 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.

Solution

Upgrade to Spring Security version 6.5.12 / 7.0.6.1 / 7.0.7 / 7.1.0.1 / 7.1.1 or later. Note that some fixed releases are available to Enterprise Support customers only; refer to the vendor advisory for details.
