Title
LatePoint - Calendar Booking Plugin for Appointments and Events <= 5.4.0 - Unauthenticated Stripe PaymentIntent Amount-Binding Bypass
Summary
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Improper Input Validation in all versions up to, and including, 5.4.0. This is due to the plugin's Stripe Connect payment processor accepting a client-supplied PaymentIntent ID. This makes it possible for unauthenticated attackers to pay an arbitrary amount by supplying a previously succeeded PaymentIntent token.
