CVE-2026-68481: Apache Cxf

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Apache Cxf: before 3.6.12 (fixed in 3.6.12); from 4.0.0, before 4.1.8 (fixed in 4.1.8); from 4.2.0, before 4.2.3 (fixed in 4.2.3)
