Description
The Booking for Appointments and Events Calendar WordPress plugin before 9.8.1 does not verify that a payment was actually taken before recording a booking as paid, trusting the payment gateway named in a public, unauthenticated booking request even when the site has never configured that gateway. This lets an unauthenticated attacker obtain confirmed, fully paid appointments and events without any payment being collected.
Affected products
- Booking for Appointments and Events Calendar: from 9.0 before 9.8.1 — fixed in 9.8.1
How to fix
Upgrade to a fixed version: Booking for Appointments and Events Calendar 9.8.1. Check the vendor advisory for mitigations.
