Name of the Vulnerable Software and Affected Versions Drupal SAML SSO - Service Provider versions 0.0.0 through 3.2.0

Description An authentication bypass issue exists where the module does not sufficiently prevent the reuse of previously accepted SAML assertions. This allows a valid assertion to be replayed within its validity period, potentially enabling remote services to perform repeated authentication attempts using stolen credentials.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
