## Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in the e4jvikwp VikBooking Hotel Booking Engine & PMS plugin for WordPress (versions up to 1.8.12). The flaw stems from a lack of proper nonce validation, which, when combined with a path traversal weakness, allows an unauthenticated attacker to trick a logged-in administrator into performing unintended actions. Specifically, an attacker can leverage this to delete arbitrary files on the server by providing manipulated file paths. Successful exploitation requires the victim to interact with a malicious link or form. The issue is resolved in version 1.8.13.
