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)

CodeIgniter is a PHP full-stack web framework. In versions prior to 4.2.7 setting `$secure` or `$httponly` value to `true` in `Config\Cookie` is not reflected in `set_cookie()` or `Response::setCookie()`. As a result cookie values are erroneously exposed to scripts. It should be noted that this vulnerability does not affect session cookies. Users are advised to upgrade to v4.2.7 or later. Users unable to upgrade are advised to manually construct their cookies either by setting the options in code or by constructing Cookie objects. Examples of each workaround are available in the linked GHSA.
