Possible XSS vulnerabilities

[enferas]

Hello,

I would like to report for some possible XSS vulnerabilities.

For example,

The injection through the news title.
The source will be inserted in the DB, then it will be passed from the DB to the view.

In file cms-master\application\controllers\news_api.php

public function insert_news(){
$this->load->model('news_model');
$data = array(
		//接收新闻的标题 用$this->input->post方法替换$_POST方法更好
		'title' => $this->input->get('title'),
		//接收新闻的内容
		'text' => $this->input->get('text'),
		//接收所选的频道
		'channel_id' => 6,
		//接收图片的地址
		//'image' => $this->input->post('image'),
		//根据所选的频道id查看频道的具体名字
		'channel_name' => "推荐",
	);
$this->news_model->add_data($data);
}

    public function add_data($data)
    {
    		$this->load->database();
        	$this->db->insert('news', $data);
    }

Then, In file cms-master\application\controllers\news.php

	public function show()
	{
		$this->load->helper('url');
		$this->load->model('news_model');
		$this->load->model('channel_model');
		//获取id和channel的对应关系表
		$data['channels'] = $this->channel_model->show_data();
		//从数据库新获取渲染到列表
		$data['news'] = $this->news_model->show_data();
		//将拿回来的图片字符串转化为数组的形式方便视图渲染
		$i = 0;
		foreach($data['news'] as $item){
			$data['news'][$i]['image'] = explode(",",$item['image']);
			$i++;
		}
		//显示退出登陆的页面
		//$this->load->view ('login/logout');
		$this->load->view('news/news_show', $data);
	}

    public function show_data()
    {
    		$this->load->database();
        $query = $this->db->get("news");
        return $query->result_array();
    }

Finally, in the view file cms-master\application\views\news\news_show.php

<?php 
foreach ($news as $item): ?>
//..
<h4 class="weui-media-box__title"><?php echo $item['title'];?></h4>
