Shield is an authentication and authorization framework for CodeIgniter 4. This vulnerability may allow SameSite Attackers to bypass the CodeIgniter4 CSRF protection mechanism with CodeIgniter Shield. For this attack to succeed, the attacker must have direct (or indirect, e.g., XSS) control over a subdomain site (e.g., https://a.example.com/) of the target site (e.g., http://example.com/). Upgrade to CodeIgniter v4.2.3 or later and Shield v1.0.0-beta.2 or later. As a workaround: set Config\Security::$csrfProtection to 'session,'remove old session data right after login (immediately after ID and password match) and regenerate CSRF token right after login (immediately after ID and password match)
