If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-5857/ (Markdown: https://insights.sbomify.com/MAL-2026-5857/index.md)","id":"MAL-2026-5857","markdown":"https://insights.sbomify.com/MAL-2026-5857/index.md","name":"MAL-2026-5857","record":{"aliases":["GHSA-hw6h-jfr8-q9v4"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On install, package.json runs a postinstall hook (`node run.js`) that triggers beacon scripts (beacon20.js, beacon_linux.js) shipped in the tarball. The beacons load `child_process`, `os`, `https`, and `http`, gather host fingerprints (os.hostname(), os.platform(), process.platform, process.env) and command output via `exec(...)`, and transmit the data outbound — beacon_linux.js issues an `http.request(...)` POST containing host details, while beacon20.js performs `https.request(...)` calls including requests against the Azure management API endpoint. There is no advertised purpose that justifies a host-info beacon firing automatically at install time, and the data collected (env vars, hostname, platform, command output) is classic installer-side reconnaissance and credential-surface telemetry. Installing this package executes the beacon on `npm install` and leaks installer-machine information to the embedded destinations.\n\nAny 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.
