Description
The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.8.17 due to missing nonce validation when the booking edit view applies submitted changes and in the sendcustomsms and sendcustomemail tasks. This makes it possible for unauthenticated attackers to modify booking details such as amounts paid, refunds, payable amounts, cancellation fees, discounts, taxes, payment method, language, room units, customer email, phone and notes, to remove stored card details, or to send arbitrary SMS and email messages, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
