WPFront User Role Editor <= 3.2.1.11184 - Limited Information Exposure

The WPFront User Role Editor plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.1.11184 via the wpfront_user_role_editor_assign_roles_user_autocomplete AJAX action. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract retrieve a list of all user email addresses who are registered on the site.
