I purchased my first home, and when I plugged a charger into a GFI outlet, the whole outlet box moved. When I unplugged the charger, it moved even more.

The wall plate isn't even flush with the wall. I removed the cover plate and took a picture (see attached.

That whole assembly in the picture moves back and forth within the wall.

What is involved in repairing this? Major electrical work? I've researched similar posts, but I can't tell if it's the same situation.

Any help will be appreciated.

Thanks.
