Security isn’t the main problem. SimpleHTTPServer is fine for small,
local, one-off servers. However, for anything large, there are two
problems: (a) its ephemeral nature, and (b) slow performance (no
caching). nginx (or apache if you must) takes only a few minutes to
set up, and does not have those problems.

CgiHTTPServer? It’s 2017 and CGI should be long dead. CGI means firing
up a Python/Perl/$cgi_language interpreter on every single HTTP
request, already a waste of time. And then, CGI scripts take input via
random environment variables (not very dependable) and output to
stdout, which is a completely broken architecture. Give up and run a
real web framework (Django) using uWSGI and nginx.
