Good job on finding that. Would report it to them if I were you.

Don't want to report it, want to see if anyone can do anything with this

It's POST XSS mate. Pretty much useless.

Sorry Haxxy baby, but are you dumb o.o?
I can make a link which on click auto-submits a POST request.
OP, got skype/xmpp?
If yes, PM me it.

Harder to use, yes, but it's more dangerous as you don't see it in the requested URL. Either way this should be reported to Mojang, maybe you'll get some money for finding the exploit.

Why is it harder to use?
It's really easy.
Make a form, use js to auto-submit it.
Ez fucking pz.

Exactly, JavaScript/HTML is required to make it work. Hence why it's harder to use on people, or implement. I totally agree with you, it's not useless.

You did not just call HaxOr❤ dumb 🤫

No one done anything with it yet? Waiting for a big hax0r to get something done

Didn't notice that. I guess i'll look around the site in abit.

I found this vulnerability in December of 2014. It is pretty much useless unless any of you have any suggestions of how to capture the authenticyToken?

It has already been reported to Mojang. When I emailed them, they stated that there will be no payouts for vulnerability disclosures. I kind of kept it to myself for a few months hoping to find bypasses with authenticyToken. Unfortunately, I failed.

I have a few more vulnerabilities but am not sure if I want to release them.

Pretty sure this isn't going to work, but I'll edit once I come up with something.
