Version data

No release is known good. There is no version list because there is no safe version.

Check what you actually have installed with npm ls vfat-tools.

The source advisories flagged the package itself rather than particular releases. Treat any resolved version as malicious and remove the dependency; there is nothing to upgrade to.

What to do

Installed one of these? Start here.

Treat the machine as compromisedUpgrading is not enough. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.

Rotate every credential that machine or CI job could reach, such as registry tokens, cloud keys, SSH keys and CI secrets, from a different machine.
Remove the dependency: no release is known good, so there is nothing to pin to. Reinstall from a clean lockfile.
Clear caches and private mirrors. Artifactory, Nexus, Verdaccio and devpi routinely keep serving a tarball after the public registry has pulled it.
Read the incident write-up. Recommended actions differ per incident, and some have specific indicators of compromise worth searching your logs for.

Check your whole project

Check every dependency, not just this one.

It is usually pulled in as a transitive dependency rather than one you installed directly. Paste your package-lock.json to check every dependency at once. It runs in your browser and nothing is uploaded.
