CVE-2022-39284

### Impact Setting `$secure` or `$httponly` value to `true` in `Config\Cookie` is not reflected in `set_cookie()` or `Response::setCookie()`. > **Note** > This vulnerability does not affect session cookies. The following code does not issue a cookie with the secure flag even if you set `$secure = true` in `Config\Cookie`. ```php helper('cookie'); $cookie = [ 'name' => $name, 'value' => $value, ]; set_cookie($cookie); // or $this->response->setCookie($cookie); ``` ### Patches Upgrade to v4.2.7 or later. ### Workarounds 1. Specify the options explicitly. ```php helper('cookie'); $cookie = [ 'name' => $name, 'value' => $value, 'secure' => true, 'httponly' => true, ]; set_cookie($cookie); // or $this->response->setCookie($cookie); ``` 2. Use Cookie object. ```php use CodeIgniter\Cookie\Cookie; helper('cookie'); $cookie = new Cookie($name, $value); set_cookie($cookie); // or $this->response->setCookie($cookie); ``` ### References - https://codeigniter4.github.io/userguide/helpers/cookie_helper.html#set_cookie - https://codeigniter4.github.io/userguide/outgoing/response.html#CodeIgniter\HTTP\Response::setCookie ### For more information If you have any questions or comments about this advisory: * Open an issue in [codeigniter4/CodeIgniter4](https://github.com/codeigniter4/CodeIgniter4/issues) * Email us at [SECURITY.md](https://github.com/codeigniter4/CodeIgniter4/blob/develop/SECURITY.md)
