Details

Cross-Site Request Forgery (CSRF) Protection Bypass Vulnerability in CodeIgniter4 ### Impact This vulnerability might allow remote attackers to bypass the CodeIgniter4 CSRF protection mechanism. ### Patches Upgrade to v4.1.9 or later. ### Workarounds These are workarounds for this vulnerability, but **you will still need to code as these after upgrading to v4.1.9**. Otherwise, the CSRF protection may be bypassed. #### When Auto-Routing is Enabled 1. Check the request method in the controller method before processing. E.g.: ```php if (strtolower($this->request->getMethod()) !== 'post') { return $this->response->setStatusCode(405)->setBody('Method Not Allowed'); } ``` #### When Auto-Routing is Disabled Do one of the following: 1. Do not use `$routes->add()`, and [use HTTP verbs in routes](https://codeigniter4.github.io/userguide/incoming/routing.html#using-http-verbs-in-routes). 2. Check the request method in the controller method before processing. E.g.: ```php if (strtolower($this->request->getMethod()) !== 'post') { return $this->response->setStatusCode(405)->setBody('Method Not Allowed'); } ``` ### References - [CodeIgniter4 CSRF protection](https://codeigniter4.github.io/userguide/libraries/security.html#cross-site-request-forgery-csrf) ### 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)
