Technical details

The vulnerability exists in the regurl parameter due to insufficient input sanitization and output escaping in the login-form.php template. Authenticated attackers with contributor-level access or above can inject arbitrary JavaScript that persists in the database. The malicious payload executes only for logged-out visitors, as the vulnerable code path is gated by !is_user_logged_in() conditions.
