Vulnerability DRUPAL-CONTRIB-2026-116

This module enables you to create one or more multisites with highly granular page permissions.

The module doesn't sufficiently sanitize HTML code contained in the page name when displayed in the built-in tree browser. This results in a cross-site scripting vulnerability that may allow attackers to execute arbitrary JavaScript in the context of the user’s session.

This vulnerability is mitigated by the fact that an attacker must have the ability to create pages whose page title supports HTML.
