Re: Fwd: Google vulnerabilities with PoC

Is this treated with the same way that says that Remote File Inclusion is not a security issue ? 

You don't follow? Implying ? 

I understand why nobody likes Google. If I 've found a vulnerability and been treated like that for trying to help, I 
would rather sell it to the black market or to some government.

The NSA maybe is happy to buy a RFI on Google, im sure they could make good use of that. Google is very deceptive in 
security matters.

To be honest, I'm not sure I follow, but I'm fairly confident that my
original point stands. If you believe that well-formed JSON objects
without padding can be read across origins within the browser, I would
love to see more information about that. (In this particular case, it
still wouldn't matter because the response doesn't contain secrets,
but it would certainly break a good chunk of the Internet.) JSONP is a
different animal.
