{"id":"CVE-2026-103525","state":"PUBLISHED","title":"FluentCart A New Era of eCommerce <= 1.7.0 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'order_id' and 'billing_address_id' Parameters","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.","publishedAt":"2026-10-16T04:27:00.357Z","updatedAt":"2026-10-16T15:09:40.130Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wpmanageninja FluentCart A New Era of eCommerce – Faster, Lighter, and Simpler"],"affected":[{"vendor":"wpmanageninja","product":"FluentCart A New Era of eCommerce – Faster, Lighter, and Simpler","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.7.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/8375a8f4-274d-4c4f-8833-067efc7e57a2?source=cve","https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L338","https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L369","https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/app/Hooks/Cart/WebCheckoutHandler.php#L132","https://plugins.trac.wordpress.org/browser/fluent-cart/tags/1.7.0/api/Checkout/CheckoutApi.php#L124","https://plugins.trac.wordpress.org/changeset?reponame=&old=3734886%40fluent-cart&new=3734886%40fluent-cart"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/103xxx/CVE-2026-103525.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-103525","state":"PUBLISHED","datePublished":"2026-10-16T04:27:00.357Z","dateUpdated":"2026-10-16T15:09:40.130Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-30T19:05:58.982Z"},"containers":{"cna":{"title":"FluentCart A New Era of eCommerce <= 1.7.0 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'order_id' and 'billing_address_id' Parameters","descriptions":[{"lang":"en","value":"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.
