Severity: low Affected versions:
- Apache CXF (org.apache.cxf:cxf-rt-rs-security-sso-oidc) 4.2.0 before 4.2.3 - Apache CXF (org.apache.cxf:cxf-rt-rs-security-sso-oidc) 4.0.0 before 4.1.8 - Apache CXF (org.apache.cxf:cxf-rt-rs-security-sso-oidc) before 3.6.12 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.
