There is no meaningful difference to people that understand the difference between the two. Unfortunately to the general public, a "hack/hacker" is scary whereas a "URL exploit" sounds closer to a technical bug. Semantics matter in the world of public perception despite the facts pointing out otherwise.

But, by that logic we're all using hacked systems; as surely we uses systems daily (OS X, Win, Linux) that are full of holes. Right? No.

There's clearly a difference in getting hacked and closing a hole.
