## Description

The EventPrime plugin for WordPress is vulnerable to Sensitive Information Exposure via the all-bookings CSV export AJAX action in all versions up to, and including, 4.3.8.0 due to an insufficient capability check that only required the edit_posts capability instead of the bookings capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to export every booking on the site, including attendee names, email addresses and payment details.
