Re: Universal XSS in all Google Services
This is much better than its competitor (Yxxxx! Inc).
We reported critical security bug to them twice. All lost to their spam quarantine. When they managed to get back to us, and white-listed our addresses, we sent the alert again, and a reminder after. We weren't sure if those two got through, but we haven't heard from them either.
Anyway, the bug was resolved (without due credit) in about a month or two.
This serves as a contrast to the prompt response that Google Security Team displayed.

If you think Google took a long time in fixing this vulnerability, think again. This python script is used in a lot of places. Try this Google Dork to see the usage of this script in almost all Google Services.
