Description

The Paid Membership, Online Courses (LMS), Ecommerce, User Registration & Login Form, User Profile & Restrict Content plugin for WordPress is vulnerable to Sensitive Information Exposure via the member directory in all versions up to, and including, 4.18.0. This is due to the directory search running a substring LIKE match against user email addresses, the search conditions being OR-ed with the directory's role restriction, and the 'sortby' parameter accepting arbitrary user meta keys. This makes it possible for unauthenticated attackers to work out members' email addresses one character at a time, list users outside the roles the directory is set to show, and infer hidden user meta by sorting on it.
