Technical details

The plugin fails to properly verify user authorization before allowing access to customer data retrieval endpoints. Although a CSRF nonce is present as a nominal protection, it is publicly emitted in the booking_package JavaScript object on any page displaying the plugin's shortcode or widget, making it trivially harvestable by unauthenticated visitors. This renders the nonce ineffective as an authentication barrier, allowing unauthorized data extraction from the booking_package_booked_customers database table.
