Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary JavaScript in an administrator's browser session.
The vulnerability exists due to cross-site scripting in src/admin/views/users.php and src/skin/js/users.js when processing a user-controlled Person name inside inline JavaScript and HTML-rendered confirmation messages. A remote user can supply a specially crafted Person name to execute arbitrary JavaScript in an administrator's browser session.
User interaction is required when an administrator opens Admin → Users and clicks one of the affected account-management actions for a user linked to the poisoned Person record.
