## Description

The LearnPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions 4.3.2 up to, and including, 4.4.11, due to a flawed ownership check in the profile order details callback of the load_content_via_ajax handler, which compares the order's user ID with the current user ID even though both are 0 for guest orders and unauthenticated visitors. This makes it possible for unauthenticated attackers to view the items, totals, status and order key of guest orders placed by other customers.
