CVE-2026-103525 Details
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.
A vulnerability exists in the FluentCart A New Era of eCommerce plugin for WordPress, in all versions through 1.7.0. The issue is an Insecure Direct Object Reference (IDOR) that allows unauthenticated attackers to access and exfiltrate personal identifiable information (PII) related to billing and shipping addresses of customers. This vulnerability arises from a lack of proper validation on user-controlled parameters, specifically 'order_id' combined with 'billing_address_id' or 'shipping_address_id'. Exploitation involves sequentially enumerating order and address ID pairs to bypass safeguards intended to prevent address reuse. The vulnerability is facilitated by an unauthenticated AJAX endpoint that only lightly throttles requests, allowing for rapid exploitation without authentication or ownership verification.
Users are advised to update the FluentCart WordPress plugin to version 1.7.1 or a later patched version.
