Revoked-token reuse via ineffective revocation state
Published Aug 6, 2026 · Updated Aug 6, 2026
Token revocation bypass in Apache CXF before 3.6.12, 4.0.0 through 4.1.7, and 4.2.0 through 4.2.2 lets remote attackers reuse revoked tokens. DefaultEncryptingOAuthDataProvider continues to decrypt revoked access and refresh tokens, so TokenIntrospectionService reports them as active after revocation. Any party holding a previously issued token can retain access to resources authorized by that token after revocation; the flaw does not grant a token that the party did not already possess.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <3.6.12
- Affected versionversion=4.0.0 <4.1.8
- Affected versionversion=4.2.0 <4.2.3
