@jasnow I believe this would be a Ruby library for interacting with the `ruby-advisory-db`, so that other tools could interface with it in the same way that `bundler-audit` does.

Maybe it could have a rudimentary CLI that could update the DB or query a specific advisory or `gem-version`.

We could create a static JSON feed for the website as yet-another-way to get the advisory data. Might be worth creating a separate issue in the [website repo](https://github.com/rubysec/rubysec.github.io/issues).

Closing since #456 was merged.

I noticed this PR was approved, but still think it's out of scope of tracking security advisories. The amount of data to track whether a gem is currently maintained is...
