 "title": "Event Tickets and Registration <= 5.30.1 - Authenticated (Contributor+) Insecure Direct Object Reference to Arbitrary Ticket and Attendee Deletion",
 "description": "The Event Tickets and Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'tribe-ticket-delete' AJAX action and the ticket DELETE REST endpoint in all versions up to, and including, 5.30.1, due to the permission check being performed against the user-supplied 'post_id' parameter instead of the post the ticket or attendee actually belongs to. This makes it possible for authenticated attackers, with contributor-level access and above, to delete tickets and attendees attached to posts they are not permitted to edit by supplying the ID of a post they can edit along with another post's ticket or attendee ID.",
