CVE-2026-68079 PUBLISHED

Apache CXF: DefaultEncryptingCodeDataProvider allows unlimited authorization code replay

Assigner: apache
Reserved: 30.07.2026 Published: 06.08.2026 Updated: 06.08.2026

In Apache CXF's DefaultEncryptingCodeDataProvider, a captured authorization code can be redeemed an unlimited number of times due to a flaw in the implementation of the removeCodeGrant functionality. This violates the RFC requirement that "The authorization code MUST NOT be used more than once." Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
