Unauthenticated booking manipulation via client-controlled payment data
Published Sep 12, 2026 · Updated Sep 12, 2026
Improper booking validation in Wpmet Rox Appointment Booking before 1.2.0 allows remote attackers to confirm bookings at arbitrary prices. The appointment-creation flow trusts the submitted order total and payment-method selection instead of recomputing the price and enforcing server-side gateway settings. No authentication is required; a public booking form is enough to create a confirmed underpriced booking or use a payment method disabled by the site.
