Ultimate Member Widgets for Elementor <= 2.3 - Missing Authorization to Unauthenticated Information Exposure

The Ultimate Member Widgets for Elementor – WordPress User Directory plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the handle_filter_users function in all versions up to, and including, 2.3. This makes it possible for unauthenticated attackers to extract partial metadata of all WordPress users, including their first name, last name and email addresses.
