Description
The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via file-type guest fields submitted through the front-end pre-check-in form in all versions up to, and including, 1.8.16, due to insufficient input sanitization and output escaping. The storeprecheckin task stores the raw guest values, and the admin booking check-in view prints them without escaping into a hidden input's value attribute. This makes it possible for unauthenticated attackers who hold a confirmed booking to inject arbitrary web scripts that execute when an administrator opens the booking check-in page.
