Google Base arrived recently, sharing the same domain as gmail, so cross site security holes in Google Base will allow access to all the gmail emails, as well as XSS phishing attacks using the google brand. Of course as you would expect for a new product from a major internet company, there’d obviously been no security testing whatsover and there were trivially obvious XSS holes in it.
Like the yahoo programmer last week, the incompetent google base programmer had simply taken a parameter from the querystring, and written it unencoded into the document. So a query *removed* performed the alert, this was fixed about 5 hours after I reported it, showing again that google don’t care about the security of our data enough to not release clearly insecure software.
