Summary

The Appointment Booking Plugin (LatePoint | Calendar & Scheduling for WordPress) is affected up to and including 5.7.2. The steps routes accept a params[presets][order_item_id] value without checking that the order item belongs to the current customer, is a bundle item, is paid, or has capacity (CWE-639). An attacker can create approved appointments against other customers' order items and read those customers' names, email addresses and order codes from the booking confirmation.

Description from the CNA

The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference / Missing Authorization in versions up to, and including, 5.7.2. This is due to the publicly reachable steps__start and steps__load_step routes accepting a params[presets][order_item_id] value that is copied verbatim into the booking object without verifying that the referenced order item belongs to the current customer, is a bundle item, is paid, or has remaining capacity — the is_bundle_scheduling() bundle discriminator is a mere !empty(order_item_id) truthiness check, and the code flow explicitly removes the customer and payment steps when this is truthy (the source even carries a TODO acknowledging the missing validation). This makes it possible for unauthenticated attackers to create approved appointments against other customers' order items and to read those customers' names, email addresses, and order codes returned in the booking confirmation.
