## Description

The EventPrime plugin for WordPress is vulnerable to Sensitive Information Exposure via the REST API single ticket endpoint (/tickets/{id}, /get_ticket/{id} and the integration 'get_ticket' action) and the ticket list handler used by the public 'eventprime/list-tickets' ability in all versions up to, and including, 4.3.8.0, due to missing checks that the ticket's parent event is visible to the current user. This makes it possible for unauthenticated attackers to retrieve ticket names, prices, capacity and parent event IDs of tickets that belong to private or draft events.
