As long as the ground is still attached, zero risk. If you disconnect
the ground and there is something bleeding current to ground, it will be
live.

I had a "hot" computer case once. If I touched it, while touching
something grounded I got a heck of a zap. Turned out the extension cord
I was using had the ground broken inside of the male end of the cord.
AC inducts current into nearby conductors real well, so it was loading
the ground wire, no longer connected to a ground, with lots of juice.
Since the case of the computer is directly connected to the ground
lead... Replacing the cord solved the problem.
