Event Booking Manager for WooCommerce < 5.3.8 - Unauthenticated Attendee PII Disclosure via Booking Confirmation Panel

Description

The plugin does not perform an ownership or authorization check before rendering booking confirmation details, allowing unauthenticated attackers to retrieve registered attendees' personal information (full name, email address, phone number, and custom registration fields) by supplying an enumerable booking reference. Exploitation is limited to sites configured to use the plugin's native (non-WooCommerce) checkout, which is not the default.
