Executive brief
The Timetics WordPress plugin, used for managing appointments and bookings, contains a flaw that allows users to bypass payment requirements. By submitting a booking with an unrecognized payment method, an attacker can secure a fully approved appointment without paying. This could lead to financial loss for service providers and unauthorized reservation of staff time or resources.
Technical details
An improper access control vulnerability exists in the Timetics WordPress plugin's REST API endpoint (/wp-json/timetics/v1/bookings). The plugin does not validate or enforce a 'pending' or 'unpaid' status when a booking is submitted with a payment method outside of its recognized gateways. An unauthenticated attacker can send a specially crafted POST request specifying an arbitrary payment method and a status of 'approved' to bypass the payment processing logic. This results in the system confirming the booking, sending confirmation emails, and reserving calendar slots without any financial transaction occurring. The issue is fixed in version 1.0.57.
