Overview

org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.

Affected versions of this package are vulnerable to Access Control Bypass. The SAML broker used within keycloak did not verify missing message signatures. As such, it is possible for an attacker to modify the SAML Response and remove the section and impersonate another user to gain unauthorized access. This is due to the SAML message is still accepted by the package after being tampered with.
