Unauthenticated order creation via unverified AJAX checkout
Published Jan 17, 2026 · Updated Jan 17, 2026
Missing authorization in Payment Button for PayPal 1.2.3.41 and earlier allows remote attackers to create arbitrary orders via HTTP requests. The wppaypalcheckout_ajax_process_order endpoint accepts untrusted POST fields and records checkout results without authentication or server-side PayPal transaction verification. Basic parameter validation must be bypassed; successful requests corrupt order data and, when purchase email is enabled, send receipts to attacker-selected addresses.
