What is CVE-2026-103518?

The FluentCart plugin for WordPress, designed to simplify eCommerce, suffers from a critical SQL injection vulnerability. This issue arises from insufficient escaping of user-supplied parameters and a lack of adequate preparation in the SQL query employed. Authenticated users with custom-level access or above can exploit this flaw by injecting additional SQL commands through the 'products[].variants[].' parameter. Particularly concerning is that non-administrator users assigned the Manager shop role on FluentCart Pro installations possess the 'products/edit' permission, enabling them to exploit this vulnerability without needing administrator privileges, potentially leading to unauthorized data extraction from the database.

Affected Version(s)
