NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-25 package and not the keycloak-25 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

A flaw was found in Keycloak. A remote attacker could bypass security controls by sending a valid SAML response from an external Identity Provider (IdP) to the Keycloak SAML endpoint for IdP-initiated broker logins. This allows the attacker to complete broker logins even when the SAML Identity Provider is disabled, leading to unauthorized authentication.
