argparse stores --check-cve-online as check_cve_online, but the code
reads check_cve_exists. This raises AttributeError every time main()
runs, even when the flag is not passed (the attribute simply does not
exist on the Namespace object).

Should this be args.check_cve_online?

Verdict - Needs revision
