    CVE-2026-16282 (GCVE-0-2026-16282)

    Title
    Appointment Hour Booking < 1.5.88 - Unauthenticated Booking Price Manipulation via tcost Parameter
    Summary
    The Appointment Hour Booking WordPress plugin before 1.5.88 does not validate a client-supplied booking price against the server-side configured service price, allowing unauthenticated users to submit an arbitrary final price (including zero or negative) that is stored as the authoritative booking price, corrupting booking and payment records.
