There are 3 different steps to perform an attack using a URL redirect: 1) trick the user 2) redirect 3) exploit .. We are using a Facebook URL to trick the user, we are using the URL redirect as the catalyst to perform an exploit. Here are some examples of the types of attacks you can perform with a URL redirect, CSRF, phishing (fake fb login), and browser exploits (javascript zombie,0days,etc). How would you have written the impact section? To be clear - I was trying to make a point when determining the impact, once you click on a bad link, bad things will happen.

Impact: Potentially allow an attacker to compromise a victim’s Facebook account and/or computer system.Do you have an actual attack in mind which could accomplish either of these goals, or is this wishful thinking? (Browser exploits don't really count, as those would work just fine with or without the redirect.) To be clear - open redirects are certainly a problem, but don't try to call them any more than that.
