CyberRota Analysis

AI-Generated

The Booking for Appointments and Events Calendar plugin for WordPress prior to version 9.8.1 is vulnerable as it fails to verify actual payment transactions before marking bookings as paid, relying instead on an unauthenticated request. This flaw allows unauthenticated attackers to exploit the system, creating confirmed bookings without any legitimate payment, potentially leading to financial losses and resource misallocation. WordPress site administrators using this plugin should prioritize updating to the latest version to mitigate this risk.

Original NVD 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.
