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. Solution: Install the latest version: * Upgrade to SAML SSO - Service Provider 3.2.0 [3].
