Affected versions
Check what you actually have installed with npm ls octopus-action.
24 new GHSA malware advisories in the 24h window ending 2026-08-27. Highlights: npm hydration-vli-ui@1.0.0 ships a Linux x86_64 ELF disguised as JavaScript, on import establishes a full-featured RAT with SSH-key theft and systemd persistence; npm commonjs-code-token postinstall pulls a token from access-token-delta.vercel.app and eval()s it; npm spotify-url-resolvers archives the project directory (including .env) hourly to a Telegram bot; PyPI pybitjs is attributed to Lazarus/PolinRider with blockchain-based C2 delivery.
Versions named here: 1.0.0, 1.0.1
What to do if you installed one of these
Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.
1.Rotate every credential that machine or CI job could reach - registry tokens, cloud keys, SSH keys, CI secrets - from a different machine.
2.Pin to a version not listed above, then reinstall from a clean lockfile.
3.Clear caches and private mirrors. Artifactory, Nexus, Verdaccio, and devpi routinely keep serving a tarball after the public registry has pulled it.
4.Read the incident write-up above - recommended actions differ per incident, and some have specific indicators of compromise worth grepping your logs for.
Check your whole project
octopus-action is one of many packages in these incidents, and 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.
Version data comes from the public advisories cited on each incident page. We list only versions those advisories name - we don't infer additional ones. Think this is wrong or incomplete? Tell us.
