CVE-2026-65583
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedApache CXF’s OIDC relying-party token validation could accept self-issued ID tokens without enforcing required claim checks (issuer/subject/audience/time and sub_jwk binding), enabling authentication bypass with crafted tokens. However, note that self-issued ID tokens are not accepted by default in the validator. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fixes this issue.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.6.124.1.84.2.3
4.2.3 (for 4.2.x), 4.1.8 (for 4.0.x-4.1.x), or 3.6.12 (for 3.x)
- Identify your current CXF version by checking your project's dependency management (Maven pom.xml, Gradle build file, or JAR manifest)
- Upgrade CXF to version 3.6.12 if using the 3.x branch
- OR upgrade CXF to version 4.1.8 if using the 4.0.x-4.1.x branch
- OR upgrade CXF to version 4.2.3 if using the 4.2.x branch
- Update the dependency in your build configuration (e.g., <version>org.apache.cxf:cxf-core:3.6.12</version> in Maven)
- Rebuild and test your application to verify the OIDC relying-party functionality still works correctly
