VLAI
Summary
Deserialization of Untrusted Data in Codeigniter4
Details

Impact

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.

Patches

Upgrade to v4.1.6 or later.

Workarounds

Do not use: - old() and form_helper - RedirectResponse::withInput() and redirect()->withInput()
