Description
The EventPrime plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'em_ticket_category_delete_ids' and 'em_ticket_individual_delete_ids' parameters of the frontend event submission (ep_save_frontend_event_submission AJAX action) and event save routines in all versions up to, and including, 4.3.6.0, due to missing validation that the ticket or ticket category IDs requested for deletion belong to the event being saved. This makes it possible for authenticated attackers, with subscriber-level access and above who are permitted to submit events (or unauthenticated attackers when anonymous event submission is enabled), to delete the tickets and ticket categories of any other event.
