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 uses cryptographic constructions that do not align with current security best practices. The module performs certain signature comparisons using non constant-time comparison logic and generates SAML request identifiers using predictable values derived from non-cryptographic random number generation. While no practical authentication bypass has been demonstrated as a result of these weaknesses alone, they may reduce the overall security margin of SAML authentication workflows.
