Keycloak: Unauthorized authentication via disabled SAML Identity Provider

發布日:2026/3/18修改日:2026/5/20

描述

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.
