NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-services package and not the keycloak-services package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in Keycloak. A remote, unauthenticated attacker can send a specially crafted XML input to the Security Assertion Markup Language (SAML) endpoint. This malicious input can cause high CPU usage and worker thread starvation, leading to a Denial of Service (DoS) where the server becomes unavailable.
