CVE-2026-65583
Last modified
CVE-2026-65583 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. 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.
