## Overview

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.

## Affected packages

- `org.keycloak:keycloak-services <= 26.2.5`
- `org.keycloak:keycloak-services >= 26.3.0, <= 26.4.7`
- `org.keycloak:keycloak-services >= 26.5.0, < 26.5.5`

## Remediation

Refer to the advisory for the patched release.
