CVE-2026-6818Public exploitNetwork attack vector

Unauthenticated stored XSS via special_requests rendering

Published Jul 8, 2026 · Updated Jul 8, 2026

Stored XSS in E4J s.r.l. Vik Booking 1.8.8 and earlier allows remote attackers to inject scripts through special_requests. The plugin stores this booking field without sufficient sanitization and later renders it without output escaping in booking-detail, edit-order, and order-list administrator views. No authentication is required to plant a payload; execution occurs when a user opens an affected administrative page, exposing that browser session to script actions in the site's origin.
