野草 Weedcms v5.2.1 任意删除文件漏洞

member.php：

if($action=='edit_member_ok'){  //member.php?action=edit_member_ok
check_request();  //检查来路
        if(!check_login()){  //检测是否登录会员
                message(array('text'=>$language['please_login'],'link'=>'member.php'));
        }

...省略一堆无关东西

$member_photo_delete=empty($_POST['member_photo_delete'])?'':trim($_POST['member_photo_delete']);

..继续省略一堆无关东西

if(!empty($member_photo_delete)){
                        @unlink(ROOT_PATH."/uploads/".$member_photo_delete); //直接删除了
