Description
The Easy PayPal Events & Tickets plugin for WordPress before version 1.4 contains an information disclosure vulnerability in the QR code scanning endpoint that allows unauthenticated attackers to enumerate and retrieve all customer order records. Attackers can iterate over sequential WordPress post IDs through the scan_qr.php endpoint to harvest the complete set of orders stored in the database without requiring authentication or prior knowledge of specific order identifiers.
