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-2026-919/ (Markdown: https://insights.sbomify.com/MAL-2026-919/index.md)","id":"MAL-2026-919","markdown":"https://insights.sbomify.com/MAL-2026-919/index.md","name":"MAL-2026-919","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"package.json declares `preinstall: node index.js`, which runs automatically on every `npm install`. index.js collects os.homedir(), os.hostname(), os.userInfo().username, dns.getServers(), the package name, __dirname, and the full package.json contents, then HTTPS POSTs them as a querystring `msg=...` parameter to `2mpf1804g4gnfnvuqqx3om0cw32vqlea.oastify.com` — a Burp Collaborator (oastify.com) subdomain used as an out-of-band recon/exfiltration channel.
