CVE-2026-2603
Red Hat Red Hat build of Keycloak 26.2, Red Hat build of Keycloak 26.2.14, Red Hat build of Keycloak 26.4 취약점
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.
