Keycloak-services: keycloak: unauthorized access via improper validation of encrypted saml assertions

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. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.
