CWE-863  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:8 keycloak-services.

NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-services package and not the keycloak-services package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider.
