Cross-Site Request Forgery (CSRF)

codeigniter4/shield is vulnerable to cross-site request forgery. The vulnerability exists in the startLogin function of Session.php, allowing same site attackers to bypass the CSRF Protection mechanism and redirect to malicious urls such as https://a.example.com/ and http://example.com/ when the Config\Security::$csrfProtection is cookie or session and Config\Security::$regenerate is true or false
