Technical details
The vulnerability exists in JWT Bearer and SAML2 Bearer grant type implementations, which do not validate the enabled/disabled status of the Identity Provider before token issuance. An attacker with knowledge of a disabled IDP's configuration can request access tokens that should not be issued, bypassing authentication controls. This is an authentication bypass affecting token generation logic.
