## Description

The Events Made Easy plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'event[event_author]' parameter of the frontend event submission form in all versions up to, and including, 3.3.7, due to the submit handler removing the 'event_author' field only for guests and accepting an arbitrary user ID from logged-in submitters. This makes it possible for authenticated attackers with contributor-level access and above (the default frontend submit permission) to create events attributed to other users, such as administrators, who then also become the default contact person for the event.
