It is usually pulled in as a transitive dependency. We do not parse RubyGems manifests yet, but the scanner checks npm and PyPI lockfiles and the incident write-ups list every affected package.
A small amount of analytics helps us understand how the scanner gets used so we can make it better. Your lockfile scanning still runs entirely in your browser. We never sell or share your data. See our Privacy Policy for details.
