这确实没有经过消毒：

如何消毒？
这里是我的完整类，我已经尝试过，但WordPress团队仍然说它没有得到适当的消毒。
以及##不安全的SQL调用
在调用数据库时，保护代码免受SQL注入漏洞的攻击是非常重要的。您需要更新代码以使用wpdb调用，并使用prepare（）查询来保护它们。

`$orderby = (isset($_REQUEST['orderby']) && in_array($_REQUEST['orderby'], array_keys($this->get_sortable_columns()))) ? $_REQUEST['orderby'] : 'country';`


`$order = (isset($_REQUEST['order']) && in_array($_REQUEST['order'], array('asc', 'desc'))) ? $_REQUEST['order'] : 'asc';`
