"text": "The Mendix SAML module insufficiently verifies the SAML assertions. This could allow unauthenticated remote attackers to bypass authentication and get access to the application.\n\nMendix has provided fix releases for the Mendix SAML module and recommends to update to the latest version.\n\nNote: For compatibility reasons, fixes for several versions of the Mendix SAML module were introduced in two release steps:\n\n- \nThe first fix versions address CVE-2023-25957. It removes the vulnerability, except when the recommended, default configuration option \n'Use Encryption' is disabled.\n\n- \nThe second fix versions address CVE-2023-29129, which removes the issue for the non default configuration as well.",
