Official Description

The WP Booking Calendar plugin for WordPress is vulnerable to Unauthenticated Post-Confirmation Booking Manipulation in all versions up to, and including, 10.10.

This makes it possible for unauthenticated attackers to manipulate their confirmed bookings, even after they have been approved.
