WP Time Slots Booking Form < 1.2.31 - Cross-Site Request Forgery

Description

The WP Time Slots Booking Form plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.30. This is due to missing or incorrect nonce validation on the 'wp_timeslotsbooking' page. This makes it possible for unauthenticated attackers to perform an unauthorized action granted they can trick a site administrator into performing an action such as clicking on a link.
