As an impact it is known to affect integrity. CVE summarizes:

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.

The weakness was published by PRISM. The advisory is available at wordfence.com. This vulnerability was named CVE-2026-12754 since 06/19/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059.007 by the MITRE ATT&CK project.
