FluentCart（“电子商务新时代——更快、更轻量、更简单”）WordPress 插件在所有 1.7.0 及更早版本中，存在通用 SQL 注入漏洞。该漏洞源于对用户提供的 参数未进行充分转义，且现有 SQL 查询缺乏必要的预处理。这使得拥有“自定义”级别及以上权限的已认证攻击者，能够向已有的 SQL 查询中追加额外的查询语句，从而从数据库中窃取敏感信息。在 FluentCart Pro 安装环境中，被分配为“商店经理（Manager）”角色的非管理员用户同样拥有 权限，因此无需管理员级访问即可利用此漏洞。

Vulnerability Title
FluentCart A New Era of eCommerce <= 1.7.0 - Authenticated (Administrator+) SQL Injection via 'products.variants' Array Keys
Source: CVE Program / CVE List V5
Vulnerability Description
The FluentCart A New Era of eCommerce – Faster, Lighter, and Simpler plugin for WordPress is vulnerable to generic SQL Injection via the 'products[*].variants[*].<attacker-chosen key>' parameter in all versions up to, and including, 1.7.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. On FluentCart Pro installs, non-administrator users assigned the Manager shop role also hold the products/edit permission and are therefore able to exploit this vulnerability without administrator-level access.
