{"id":"CVE-2026-109991","published":"2026-11-07T12:17:42.267","lastModified":"2026-11-07T19:17:17.740","description":"The FunnelKit Payment Gateway for Stripe WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.15.0.2 via the 'order-pay (WP query var from /checkout/order-pay/<ID>/)' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to read the full billing PII — including name, email address, phone number, and complete street address — of any store order by enumerating sequential order IDs, as this data is emitted into the inline fkwcs_data JavaScript object via wp_localize_script on every matching page response. Exploitation occurs even when WooCommerce itself rejects the order-pay page request, because the plugin's wp_localize_script call runs independently of WooCommerce's own order-key validation on the same request.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/funnelkit-stripe-woo-payment-gateway/tags/1.15.0.1/includes/abstract-payment-gateway.php#L295","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/funnelkit-stripe-woo-payment-gateway/tags/1.15.0.1/includes/abstract-payment-gateway.php#L317","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/funnelkit-stripe-woo-payment-gateway/tags/1.15.0.1/includes/abstract-payment-gateway.php#L364","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3741799%40funnelkit-stripe-woo-payment-gateway&new=3741799%40funnelkit-stripe-woo-payment-gateway","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b8d77b41-f535-4e60-a850-881be8dee458?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
