|---|
| 説明 | `App/Home/Model/UserModel.class.php:82-84` identifies the current user solely through `cookie('username')`, and `App/Home/Model/CommentModel.class.php:13-21` writes that cookie value as the comment author. The cookie helper in `ThinkPHP/Common/functions.php:1390-1415` stores and reads scalar cookie values without signing or encryption, while `Home/CommentController.class.php:8-16` performs no server-side user authentication. An attacker can send a manually chosen `username` cookie for an existing account and publish comments attributed to that account.
