Deserialization of Untrusted Data was found in the old() function in CodeIgniter4.
Remote attackers may inject auto-loadable arbitrary objects with this vulnerability,
and possibly execute existing PHP code on the server.
We are aware of a working exploit, which can lead to SQL injection.
Upgrade to v4.1.6 or later.
Do not use:
- old() and form_helper
- RedirectResponse::withInput() and redirect()->withInput()
