Vulnerability DRUPAL-CONTRIB-2026-336

This module enables you to display users by a configurable "real name" pattern built from tokens, instead of by their username.

The module does not sufficiently sanitize user input used in name patterns.
A user can place Twig syntax in their own profile data and have it evaluated when their name is displayed.

This vulnerability is mitigated by the fact that the site must be configured with a real name pattern that includes user-supplied data, and the attacker must be able to edit that data on their own account.
