BookingPress < 1.0.82 - Authenticated (Customer+) Insecure Direct Object Reference

Description The BookingPress – Appointment Booking Calendar Plugin and Online Scheduling Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.0.81 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with customer-level access and above, to access or perform an action on an object they should not have access to.
