Kerentanan Authentication Bypass by Primary Weakness pada redhat build of keycloak, redhat keycloak. Skor CVSS 3.1 8.8 (High) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in org.keycloak.broker.saml. When a disabled Security Assertion Markup Language (SAML) client is configured as an Identity Provider (IdP)-initiated broker landing target, it can still complete the login process and establish a Single Sign-On (SSO) session. This allows a remote attacker to gain unauthorized access to other enabled clients without re-authentication, effectively bypassing security restrictions.
