The Booking X plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the export_now() function in versions 1.0 to 1.1.2. This makes it possible for unauthenticated attackers to download all plugin data, including user accounts, user meta, and PayPal credentials, by issuing a crafted POST request.
