Technical description
The Course Booking System plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check in the csv-export.php file in all versions up to, and including, 6.1.5. This makes it possible for unauthenticated attackers to directly access the file and obtain an export of all booking data.
