The Rox Appointment Booking WordPress plugin before 1.2.0 does not perform any capability or authorization check when saving its holiday schedule, allowing unauthenticated attackers to overwrite the dates the booking system treats as unavailable, which can block legitimate bookings or open dates the site owner intended to keep closed.
