Description

Apache 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.
