Salon booking system < 10.17 - Cross-Site Request Forgery to Arbitrary Post/Page Deletion

Description

The Salon Booking System, Appointment Scheduling for Salons, Spas & Small Businesses plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 10.16. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to delete content granted they can trick a site administrator into performing an action such as clicking on a link.
