Technical Description

A flaw was found in Keycloak. An unauthenticated remote attacker can trigger an application level Denial of Service (DoS) by sending a highly compressed SAMLRequest through the SAML Redirect Binding.

This vulnerability allows an attacker to disrupt the availability of the service.
