DRUPAL-CONTRIB-2026-026

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.

A visitor who successfully logs in to their Identity Provider and is denied access to Drupal through custom code or a server error will maintain their session at the Identity Provider, possibly leading to access bypass situations, especially in a shared computing environment.
