This module allows you to configure your Drupal site as a SAML 2.0 Service Provider so that users can authenticate through an external identity provider.
The module stores sensitive authentication information in a manner that could allow disclosure to users with access to configuration or related system data.
This vulnerability is mitigated by the fact that an attacker must first obtain access to configuration or underlying storage mechanisms.
