Hi,
I just noticed ohloh.net has a crossdomain file (http://www.ohloh.net/crossdomain.xml) with no restrictions.
By doing so you just enabled a big CSRF security hole, pretty much allowing any flash app performing actions on your users' behalf.
It is strongly adviced to create a separate domain for your api's (e.g.: api.ohloh.net) and not enabling any cookies there..
Hope this helps, Evert
