CVE-2026-15346
VikBooking Hotel Booking Engine & PMS <= 1.8.13 - Reflected Cross-Site Scripting via 'category_id' Parameter
Description
The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'category_id' parameter in all versions up to, and including, 1.8.13 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. This is limited to browsers that support access keys as the injection is in a hidden element.
