Overview
org.apache.cxf:cxf-rt-rs-security-sso-oidc is an Apache CXF Runtime OpenId Connect library.
Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the OIDC relying-party token validation process. An attacker can bypass authentication by submitting crafted self-issued ID tokens that are not properly validated for required claims such as issuer, subject, audience, time, and sub_jwk binding. This is only exploitable if self-issued ID tokens are explicitly accepted in the validator configuration.
