## Technical details

A Reflected Cross-Site Scripting (XSS) vulnerability exists in the VikBooking Hotel Booking Engine & PMS plugin for WordPress due to insufficient sanitization and escaping of the 'layoutstyle' parameter. The vulnerability is specifically located within the 'roomslist' view context, triggered when the [vikbooking view="roomslist"] shortcode is rendered. An unauthenticated attacker can exploit this by crafting a malicious URL containing a script payload and persuading a user to visit it. Successful exploitation allows the execution of arbitrary JavaScript in the context of the victim's browser session. The issue is addressed in version 1.8.13.
