Up to the RM team to decide is this minor security fix is worth going into such an old branch. Consider our statement about http.server in https://docs.python.org/3.7/library/http.server.html.

FWIW I did merge #94093 and #94094. For consistency it'd be good to merge this one as well. That being said, I'm not planning any security releases just for this change as http.server is not fit for production use.
