| Doc Text: |
A flaw was found in Apache CXF. The `JwtAccessTokenValidator` class fails to properly validate the 'aud' (Audience) claims within incoming JSON Web Token (JWT) access tokens. This vulnerability allows an attacker to reuse a JWT, originally intended for one resource server, against a different resource server. This can lead to token confusion and routing attacks, potentially granting unauthorized access or information disclosure.
