BIT-KEYCLOAK-2026-3047 Org.keycloak.broker.saml: keycloak saml broker: authentication bypass due to disabled saml client completing idp-initiated login

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...

BIT-KEYCLOAK-2026-2603 Keycloak: keycloak: unauthorized authentication via disabled saml identity provider

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...

BIT-KEYCLOAK-2026-2575 Keycloak: keycloak: denial of service due to excessive samlrequest decompression

A flaw was found in Keycloak. An unauthenticated remote attacker can trigger an application level Denial of Service DoS by sending a highly compressed SAMLRequest through the SAML Redirect Binding. The server fails to enforce size limits during DEFLATE decompression, leading to an OutOfMemoryErro...

BIT-KEYCLOAK-2026-2092 Keycloak-services: keycloak: unauthorized access via improper validation of encrypted saml assertions

A flaw was found in Keycloak. Keycloak's Security Assertion Markup Language SAML broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response. Thi...

A flaw was found in the SAML metadata import functionality of the keycloak-services component, which is the core engine for identity brokering in Red Hat Build of Keycloak. When importing identity provider metadata that lacks specific usage attributes for keys, the system incorrectly disables...

BIT-KEYCLOAK-2026-16442 Keycloak-services: keycloak-services: saml idp-initiated broker login bypasses link-only restriction

A flaw was found in the SAML broker component of Keycloak, which is used to manage identity federation and user authentication. The issue occurs because the IdP-initiated Single Sign-On endpoint fails to check if a provider is restricted to account linking only. This allows an attacker with contr...

BIT-KEYCLOAK-2024-7341 Wildfly-elytron: org.keycloak/keycloak-services: session fixation in elytron saml adapters

A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authenticati...
