CVE-2026-105258 - The Appointment Booking Plugin WordPress plugin before 5.7.6 does not escape several booking-form step content settings
The Appointment Booking Plugin WordPress plugin before 5.7.6 does not escape several booking-form step content settings before rendering them on the public booking form, allowing high-privilege users such as administrators to inject JavaScript that executes in the browser of any visitor who loads the form; on multisite, where administrators do not hold the unfiltered_html capability, this crosses a privilege boundary to unauthenticated visitors.
