Summary
The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'layoutstyle' parameter in all versions up to and including 1.8.12 due to insufficient input sanitization and output escaping.

An unauthenticated attacker can inject arbitrary web scripts that execute in the victim's browser upon clicking a crafted link, potentially leading to session hijacking, malicious redirects, or data theft.
Recommendation
Update the VikBooking plugin to a version newer than 1.8.12 as soon as a patch is released. Until then, temporarily disable the [vikbooking view="roomslist"] shortcode or restrict access to pages using it.

Original NVD description (English source)
The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'layoutstyle' parameter in all versions up to, and including, 1.8.12 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires the targeted page to render the [vikbooking view="roomslist"] shortcode, as the vulnerable layoutstyle parameter is only processed in that view context.
