Summary
Cross-Site Request Forgery (CSRF) Protection Bypass Vulnerability in CodeIgniter4
Details

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.:

        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. 2. 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');
        }
