Technical details
A DOM-based Cross-Site Scripting (XSS) vulnerability exists in the VikBooking Hotel Booking Engine & PMS plugin (versions up to and including 1.8.9). The flaw stems from improper neutralization of user-supplied input during web page generation, specifically within the Document Object Model (DOM) environment. An unauthenticated remote attacker can exploit this by tricking a user into clicking a specially crafted link. Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the victim's browser session, potentially leading to credential theft or unauthorized administrative actions.
