DRUPAL-CONTRIB-2026-027

Details

This module enables you to use an external OpenID Connect login provider to authenticate and log in users on your site. If a user signs in with a login provider for the first time on the website, a new Drupal user will be created.

The module doesn't sufficiently validate the uniqueness of certain user fields depending on the database engine and its collation.

As a result, a user may be able to register with the same email address as another user.

This may lead to data integrity issues.
