This might be the most valid use of the "request changes" button ever... but for some reason I'm seeing 0 changes in this PR. I think maybe you overwrote your branch or something?

Ooops. No idea how that happenned but hopefully the correct code is now available.

My merge of the exploited cves code caused a conflict. I've manually resolved it through the web interface.

@anthonyharrison looks like I broke the linting, if you've got a chance to update it.

[anthonyharrison]

@terriko Fixed the linting problem. Ready for review.

Looks great, thank you! This should make moving the db around much safer and significantly more clear for the users who need to do that. I wonder if we could use this to do improve our github caching by having a copy in the repo?
