This has a CVE number allocated (CVE-2022-29072) and the README mentions 7-zip disputing that this is their problem (rather, some underlying Windows component).
They say, form K7804? But your child, and that sounds like a lot of work to help you.. will you pay me to waste my time to help you?
You say, no guarantees that I'll pay you but if you don't inform me responsibly, I'll tell everyone you are the bad person here.
This is Microsoft's bug that affects many programs. Was Microsoft informed before this exploit was made public? What does it buy anyone to throw this out in the public first? There is no indication that the exploit finder was hunting a bounty or denied a bounty. Afaict you fabricated a controversial story in your head then tried to explain it to everyone else.
And also, disclosure actually makes attackers aware of the vulnerability. So, it is like informing a radio station which will broadcast out the message. And while many bus drivers listen to this ratio station, it is actually really popular among a set of people who enjoy crashing into misconfigured buses like this to cause mayhem.
I'm not sure how to fit the state sponsored bus crashers into the analogy. Actually I'm beginning to think it isn't a very useful analogy at all.
