重要更新：Youbbs发现SQL注入漏洞
存在问题的版本： v1.04，v2.0
v1.04把：
// 获取当前用户
$cur_user = null;
$cur_uid = $_COOKIE['cur_uid'];
$cur_uname = $_COOKIE['cur_uname'];
$cur_ucode = $_COOKIE['cur_ucode'];
替换为：
// 获取当前用户
$cur_user = null;
$cur_uid = isset($_COOKIE['cur_uid']) ? intval($_COOKIE['cur_uid']) : '';
$cur_uname = isset($_COOKIE['cur_uname']) ? $_COOKIE['cur_uname'] : '';
$cur_ucode = isset($_COOKIE['cur_ucode']) ? $_COOKIE['cur_ucode'] : '';
v2.0把：
// 获取当前用户
$cur_user = null;
$cur_uid = isset($_COOKIE['cur_uid']) ? $_COOKIE['cur_uid'] : '';
$cur_uname = isset($_COOKIE['cur_uname']) ? $_COOKIE['cur_uname'] : '';
$cur_ucode = isset($_COOKIE['cur_ucode']) ? $_COOKIE['cur_ucode'] : '';
替换为：
// 获取当前用户
$cur_user = null;
$cur_uid = isset($_COOKIE['cur_uid']) ? intval($_COOKIE['cur_uid']) : '';
$cur_uname = isset($_COOKIE['cur_uname']) ? $_COOKIE['cur_uname'] : '';
$cur_ucode = isset($_COOKIE['cur_ucode']) ? $_COOKIE['cur_ucode'] : '';
