CVE-2026-68481: CWE-672 Operation on a Resource after Expiration or Release in Apache Software Foundation Apache CXF
Apache CXF's DefaultEncryptingOAuthDataProvider improperly handles revoked access and refresh tokens, allowing them to decrypt successfully and report as active via TokenIntrospectionService. This behavior violates RFC requirements that revoked tokens must be invalidated and introspection must return active:false. The issue affects multiple versions prior to fixed releases. Users are advised to upgrade to versions 4.2.3, 4.1.8, or 3.6.12 where the problem is resolved.
AI Analysis
Technical Summary
CVE-2026-68481 is a vulnerability in Apache CXF's DefaultEncryptingOAuthDataProvider where revoked access and refresh tokens continue to decrypt successfully and are reported as active by the TokenIntrospectionService. This violates OAuth RFC stipulations that revoked tokens must be invalidated and introspection must indicate inactive status. The flaw corresponds to CWE-672 (Operation on a Resource after Expiration or Release). The vulnerability affects Apache CXF versions 4.0.0, 4.2.0, and versions prior to 4.1.8, 4.2.3, and 3.6.12. Upgrading to 4.2.3, 4.1.8, or 3.6.12 mitigates the issue.
Potential Impact
The vulnerability allows revoked OAuth tokens to remain valid for decryption and appear active during introspection, potentially enabling unauthorized access or token misuse. The confidentiality of protected resources could be compromised as the system fails to properly invalidate tokens as required by the OAuth specification. There is no indication of impact to integrity or availability. No known exploits in the wild have been reported.
Mitigation Recommendations
A fix is available. Users should upgrade Apache CXF to versions 4.2.3, 4.1.8, or 3.6.12 to resolve this vulnerability. No other mitigations are specified or required once the upgrade is applied.
