**Name of the Vulnerable Software and Affected Versions** Restrict Usernames Emails Characters WordPress plugin versions prior to 3.1.4 **Description** The issue allows high privilege users, such as admins, to perform Cross-Site Scripting attacks, even when unfiltered html is disallowed, due to the plugin not sanitizing and escaping some of its settings. **Recommendations** For versions prior to 3.1.4, update to version 3.1.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's settings for high privilege users until the update is applied.
