CVE-2026-68481: CWE-672 Operation on a Resource after Expiration or Release in Apache Software Foundation Apache CXF
In Apache CXF's DefaultEncryptingOAuthDataProvider, revoked access tokens still decrypt successfully, and TokenIntrospectionService reports active:true. The same applies to refresh tokens. This violates the RFC stipulations that 'The authorization server MUST invalidate the token.' and 'introspection of a revoked token MUST return {"active":false}'. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
AI Analysis
Technical Summary
The vulnerability in Apache CXF's DefaultEncryptingOAuthDataProvider causes revoked access and refresh tokens to remain decryptable and reported as active by the TokenIntrospectionService. This violates OAuth RFC stipulations requiring that revoked tokens be invalidated and introspection responses for revoked tokens return active:false. The flaw is classified under CWE-672 (Operation on a Resource after Expiration or Release). Affected versions include 4.0.0, 4.2.0, and versions prior to 4.1.8, 4.2.3, and 3.6.12. Users are advised to upgrade to fixed versions 4.2.3, 4.1.8, or 3.6.12.
Potential Impact
Because revoked tokens are still accepted as valid and decryptable, this vulnerability can lead to unauthorized access by allowing use of tokens that should have been invalidated. This undermines token revocation mechanisms and could allow attackers or unauthorized users to maintain access beyond intended expiration or revocation.
Mitigation Recommendations
Users should upgrade Apache CXF to versions 4.2.3, 4.1.8, or 3.6.12 where this issue is fixed. No other mitigations are specified. Patch status is confirmed by vendor advisory information embedded in the description.
