Vendor and ecosystem advisories describing this.

WID-SEC-W-2026-0599Drupal Extensions: Mehrere SchwachstellenDeutsch2026-03-04csaf · cert_bundDE
Ein Angreifer kann mehrere Schwachstellen in verschiedenen Drupal-Erweiterungen ausnutzen, um Sicherheitsvorkehrungen zu umgehen, Cross-Site-Scripting-Angriffe durchzuführen, Daten zu manipulieren oder vertrauliche Informationen offenzulegen.
DRUPAL-CONTRIB-2026-0272026-03-04vendor · osvUS
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.
