CWE-1287

Description

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.

Affected configurations

• redhat build of keycloak (>= 26.2 < 26.2.14) • redhat build of keycloak (>= 26.4 < 26.4.10)
