CVE-2026-65583
Full vulnerability record from the local CVENow database.
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.

"value": "La validación de tokens de parte confiable OIDC de Apache CXF podría aceptar tokens de ID autoemitidos sin aplicar las comprobaciones de reclamaciones requeridas (emisor/sujeto/audiencia/tiempo y enlace sub_jwk), lo que permitiría la omisión de autenticación con tokens manipulados. Sin embargo, tenga en cuenta que los tokens de ID autoemitidos no se aceptan por defecto en el validador. Se recomienda a los usuarios actualizar a las versiones 4.2.3 o 4.1.8 o 3.6.12, que corrige este problema."
