Title
Keycloak: keycloak: unauthorized authentication via disabled saml identity provider
Summary
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.
Severity ?

Title
Keycloak-services: keycloak: unauthorized access via improper validation of encrypted saml assertions
Summary
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. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.
Severity ?

Title
Org.keycloak.broker.saml: keycloak saml broker: authentication bypass due to disabled saml client completing idp-initiated login
Summary
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.
Severity ?
8.8 (High)

Title
Keycloak: keycloak: unauthorized authentication via disabled saml identity provider
Summary
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.
Severity ?
8.1 (High)

Title
Keycloak-services: keycloak: unauthorized access via improper validation of encrypted saml assertions
Summary
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. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.
Severity ?
7.7 (High)

CVE-2026-3047 (GCVE-0-2026-3047)
Vulnerability from cvelistv5 – Published: 2026-03-05 18:28 – Updated: 2026-03-06 18:13

Title
Org.keycloak.broker.saml: keycloak saml broker: authentication bypass due to disabled saml client completing idp-initiated login
Summary
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.
Severity ?
8.8 (High)
CWE
- CWE-305 - Authentication Bypass by Primary Weakness
