From what I can tell, the vulnerability wasn't even fixed: they just.. changed their spam filter? Whatever that means.
So for this to work still, you need to bypass a spam filter.
They should just force DMARC and SPF like Google has done, and say "your fault if you misconfigure". Also default-off for the CC thing would be a good idea, too, with a warning of what could happen if they turn it on. Alternatively making a non-guessable id for the email.
