MAL-2026-10198 Malicious code in polylabel-web-lib (npm)

[email protected] ships an empty index.js stub and declares its only runtime dependency as a direct tarball URL on a Google Cloud Storage bucket: "ltidisafe": "https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.2.2.tgz". On npm install, npm fetches this out-of-registry tarball and runs any lifecycle scripts it contains, so the bucket owner controls arbitrary install-time code that executes on the installer's machine. The tarball host is not the npm registry, is not tied to an established publisher CDN for this name, and its contents are mutable at the bucket owner's discretion. The package's own code has no functional purpose beyond smuggling this out-of-registry dependency into installer environments, matching the dependency-smuggling / lure shape used to deliver install-time payloads.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
