Which versions of volume-viz are malicious?

The following npm versions of volume-viz are flagged malicious: 5.5.5. Treat any of these as compromised.

How do I remediate volume-viz if I installed it?

Remove volume-viz from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed volume-viz — how do I know if it already compromised me?

If volume-viz was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

How do I find volume-viz across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for volume-viz (version 5.5.5).
