Description
The RepairBuddy – Repair Shop CRM & Booking Plugin for WordPress plugin for WordPress is vulnerable to unauthorized data deletion via the wcrb_delete_appointment AJAX action in all versions up to, and including, 4.1236, due to a missing capability check. The handler only checks a nonce, which is printed on every front-end page, and does not check the user's role or whether the user owns the appointment. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete any appointment.
