 "title": "ProfilePress – Paid Membership, Online Courses (LMS), Ecommerce, User Registration & Login Form, User Profile & Restrict Content <= 4.18.0 - Unauthenticated Arbitrary Shortcode Execution via Member Directory Search Term",
 "description": "The Paid Membership, Online Courses (LMS), Ecommerce, User Registration & Login Form, User Profile & Restrict Content plugin for WordPress is vulnerable to arbitrary shortcode execution via the drag-and-drop member directory search term in all versions up to, and including, 4.18.0. This is due to the search term from the 'filter<ID>' query parameter being reflected into the directory's search field, which is HTML-escaped but does not have its shortcode brackets neutralized, before the assembled directory markup is passed through do_shortcode(). This makes it possible for unauthenticated attackers to execute arbitrary shortcodes on the site.",
