Have the CI process attempt to automatically bump gems in response to CVEs

Is there any merit in getting the CI server to attempt to patch-version bump dependencies when we get CVE warnings? I.e. update the gem and then commit the vendored gem and Gemfile changes if all tests pass?

I’m wondering if trying it at the end of the main CI loop would be sensible, because no point doing it in the middle of a stream of commits being processed, and that way I think you’d also get the “cleanup” logic for free. I don’t think you could limit to patch-version bumps as a) not everything is semantically versioned, and b) the CVE fix might be a bigger change (they rarely are, though). You’d be relying on the test suite to detect regressions, but think this is reasonable.
If a process watching for commits is also committing, it would would need to be mindful of other commits made in the interim - i.e. would need to remember the last commit that was properly “CI’d” , and start again from there, rather than from a CVE-addressing commit.
