CVE-2026-11887Public exploitNetwork attack vector

Booking approval bypass via unchecked AJAX action

Published Jul 1, 2026 · Updated Jul 1, 2026

Missing authorization in Salon Booking System before 10.30.20 allows remote authenticated users to bypass manual booking approval. The salon AJAX action dispatches the SetDefaultBookingStatus method and accepts status=confirmed without a capability check. Subscriber-level access is sufficient to change the default booking status, causing new bookings to be confirmed without manual review.
