CVE-2026-12972Public exploitNetwork attack vector

Unauthenticated order metadata tampering via unchecked AJAX handler

Published Jul 20, 2026 · Updated Jul 20, 2026

Missing authorization in PayPlus Payment Gateway before 8.2.2 allows remote attackers to alter order metadata via an AJAX request. The make-hosted-payment action accepts an attacker-selected order_id and page_request_uid, then saves the value as payplus_page_request_uid without verifying order ownership. The gateway must be enabled and a classic checkout page must expose its frontend nonce; the demonstrated consequence is modification of arbitrary orders' payment-request metadata.
