Think of an enterprise enviornment where someone is signed into your  
corporate app via SSO for 8 or more hours a day. Take your photo, rip  
out the CSRF token, and email or IM a link to that user. You do not  
need the session ID and this does not depend on any other weaknesses.

Keep sensitive data out of GET requests. GET requests - and GET  
parameters leak all over the place as we talked about in earlier  
posts. (no pun intended)

PS: But I guess we don't need to worry about this. We can just write  
all kinds of insecure crap - and then we will be saved (haaalayluya)  
by automated and scalable black box testing! ;)
