LatePoint is a WordPress plugin for managing appointment bookings and scheduling.

## Technical details

The plugin's steps__start and steps__load_step routes accept an order_item_id parameter without validating ownership, payment status, or bundle capacity. The is_bundle_scheduling() check uses only an empty() truthiness test, and when bypassed, the code skips customer and payment verification steps. An unauthenticated network attacker can exploit this to create appointments on arbitrary customer order items and exfiltrate customer PII returned in booking confirmations.
