Description 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 Check the request method in the controller method before processing. E.g.: 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: Do not use $routes->add(), and use HTTP verbs in routes. Check the request method in the controller method before processing. E.g.: if (strtolower($this->request->getMethod()) !== ‘post’) { return $this->response->setStatusCode(405)->setBody(‘Method Not Allowed’); } References CodeIgniter4 CSRF protection For more information If you have any questions or comments about this advisory: Open an issue in codeigniter4/CodeIgniter4 Email us at SECURITY.md
