## Overview

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 contain an improper authentication vulnerability in SAML processing. In deployments that use SAML authentication, an unauthenticated remote attacker could cause the affected server to accept an assertion that should be rejected, potentially resulting in unauthorized access.
