@jeffpaul @TheLastCicada : This is taking advantage of methods introduced in https://github.com/10up/wpcli-vulnerability-scanner/pull/50, as you can see has taken that as a base branch. Let me know if you consider is best for history preserve reasons to start from the develop branch and then manually merge these methods. Also, I'll need help with unit test. Thanks!
