You mean when the inside air pressure is low enough. Aircraft doors fit like a plug, held in by air pressure in the cabin. If you look when they are opened they all move inward first. This is why they can't be opened mid-flight.

At the point where they can be opened, the pressure differential is going to be so low that nothing bad is going to happen, other than maybe someone's bag in the exit row being blown out by the wind. Plus everyone should be strapped in at that point.
