It's a good thing that Stephen was made aware of this security hole, but the author could have informed him a lot more effectively.

If someone broke into my house and I found out about it on Hacker News because they set up a webcam in my living room, I suppose it would be a good thing that I found out about a security problem in my home, but I certainly wouldn't be happy about it.

Fair enough, although it's a much more graphic illustration of the problem actually seeing the results (rather than simply "your site isn't very secure", "your front door lock is a bit loose"). I know it made much more impact on me than it would have if I'd read an article about the possibility of it happening. Although I suspect that if he'd just mailed the username/password to Stephen that would have been example enough.

Kind of scary how many of these sites are almost certainly out there, though.
