What is CVE-2026-15401?

The VikBooking Hotel Booking Engine & PMS plugin for WordPress suffers from a stored cross-site scripting vulnerability due to inadequate input sanitization and output escaping in the 'vbfX' parameter. This flaw allows unauthenticated attackers to inject malicious scripts that execute when users access compromised pages. The vulnerability arises as the vbfX custom-field can be stored without proper capability checks during the public-facing saveorder task, making it susceptible to unauthenticated exploit attempts.

Affected Version(s)

VikBooking Hotel Booking Engine & PMS 0 <= 1.8.13
