Advisory details

Keycloak's 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, injecting an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.
