Read this one, specifically that attack on github (you have to scroll

wildcard redirect uri patterns are pretty scary!

I think we're pretty good, the ones I worry about is relative urls in
redirect URI checks i.e.
"http://cloud.com/provisioned/good-site/../hacker-site"
I'll log a bug for this if you agree that relative redirect URLs
shouldn't be allowed. (Those containing "." and "..")
Another really dangerous thing that we do is have full-scope-allowed set
to true by default. If a rogue client gets registered, they pretty much
have access to every single application the user can access with all of
their privileges.
