Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WordPress 的 LearnPress 插件在 4.4.4 及之前版本中， AJAX 操作的 参数存在 SQL 注入漏洞。 其成因在于对用户输入的 参数未进行充分转义，且现有 SQL 查询缺乏充分的预处理。在 和 函数中，仅对字面量 和 进行了规范化处理，而其他由攻击者控制的字符串会被直接赋值给过滤器的 属性，并在未使用 或标识符白名单的情况下直接拼接到 子句中。 这使得拥有管理员级别及以上权限的已认证攻击者能够将额外的 SQL 查询追加到已有的查询中，从而从数据库中窃取敏感信息。

Vulnerability Title
LearnPress <= 4.4.4 - Authenticated (Administrator+) SQL Injection via 'orderby' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The LearnPress plugin for WordPress is vulnerable to SQL Injection via the 'orderby' parameter of the export_order_csv AJAX action in versions up to, and including, 4.4.4. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the LP_Order::handle_params_query_list_orders() and DataBase::execute() functions — only the literal values 'date' and 'title' are normalized, while any other attacker-controlled string is assigned directly to the filter's order_by property and concatenated into the ORDER BY clause without $wpdb->prepare() or an identifier whitelist. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
