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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1794050793813,"publishedAt":1794050793813,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b8d77b41-f535-4e60-a850-881be8dee458?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/funnelkit-stripe-woo-payment-gateway/tags/1.15.0.1/includes/abstract-payment-gateway.php#L364"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/funnelkit-stripe-woo-payment-gateway/tags/1.15.0.1/includes/abstract-payment-gateway.php#L317"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/funnelkit-stripe-woo-payment-gateway/tags/1.15.0.1/includes/abstract-payment-gateway.php#L295"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3741799%40funnelkit-stripe-woo-payment-gateway&new=3741799%40funnelkit-stripe-woo-payment-gateway"}],"remediation":[],"revision":"4149f423dcfeedd6da5fa67ecd55a1a18dea52222fc891c809774c5014f1d5b4","sources":[{"modifiedAt":1794050793813,"name":"CNA: Wordfence","retrievedAt":1794053376365,"url":"https://www.cve.org/CVERecord?id=CVE-2026-109991"}],"ssvc":null,"status":"published","title":"FunnelKit Payment Gateway for Stripe WooCommerce <= 1.15.0.2 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Exposure via 'order-pay' URL Path Parameter","updatedAt":1794053376365}
