Access violation vulnerability in Appointment & Event Booking Calendar Plugin – Webba Booking 5.0.48

The Appointment & Event Booking Calendar Plugin for WordPress, called Webba Booking, has a security issue that could allow unauthorized changes to be made to its data. This is because the save_appearance() function does not have a proper check for user permissions in all versions up to 5.0.48. This means that users with Subscriber-level access or higher could potentially change the look of the booking form.
