VikBooking Hotel Booking Engine & PMS <= 1.7.2 - Cross-Site Request Forgery to Settings Update

The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.7.2. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
