Mass Contact - Moderately Critical - Cross Site Scripting (XSS) - SA-CONTRIB-2015-144

This module allows anyone with permission to send a single message to multiple users of a site, using the site’s roles and/or taxonomy functionality.

The module doesn’t sufficiently sanitize the category labels when they are displayed.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission “administer mass contact”.
