Attackers can supply a valid _paypal_order_id to trigger payment_complete() without verifying the capture status or amount, causing the store to fulfill goods or services that were never paid for and resulting in direct financial loss to the merchant.","published":"2026-11-12T18:17:42.423","modified":"2026-11-12T18:17:42.423","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://wordpress.org/plugins/woocommerce-paypal-pro-payment-gateway/#developers"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/woocommerce-paypal-pro-payment-gateway-payment-bypass-via-pp-capture-order"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-12T18:17:42.423"}}
