The Appointment & Event Booking Calendar Plugin – Webba Booking plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_appearance() function in all versions up to, and including, 5.0.48. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the booking form's CSS.
