{"id":"CVE-2026-103525","published":"2026-10-16T05:17:28.210","lastModified":"2026-10-16T15:17:02.273","description":"The FluentCart A New Era of eCommerce – Faster, Lighter, and Simpler plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.7.0 via the 'order_id + billing_address_id (also shipping_address_id)' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to read and exfiltrate another customer's stored billing and shipping address PII — including street address, city, state, postcode, phone number, company name, VAT number, and legal registration ID — by enumerating sequential AUTO_INCREMENT order and address ID pairs. The id-equality guard intended to restrict address reuse is bypassed because the attacker controls both halves of the compared pair, and the unauthenticated AJAX entry point imposes only a soft rate limit of 5 requests per 60 seconds rather than any authentication or ownership check.","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/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L124","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L338","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L369","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/app/Hooks/Cart/WebCheckoutHandler.php#L132","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3734886%40fluent-cart&new=3734886%40fluent-cart","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/8375a8f4-274d-4c4f-8833-067efc7e57a2?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
