CVE-2026-15401Network attack vector

Unauthenticated stored XSS via vbfX custom field

Published Jul 24, 2026 · Updated Jul 24, 2026

Stored XSS in E4J s.r.l. Vik Booking 1.8.13 and earlier allows remote attackers to inject scripts through the vbfX parameter. The public saveorder task stores the custom-field value without sufficient sanitization, and the order-edit view renders it without adequate output escaping. No authentication or capability check protects submission by default, so the stored payload executes when a user opens the affected order page.
