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-2026-4193/ (Markdown: https://insights.sbomify.com/MAL-2026-4193/index.md)","id":"MAL-2026-4193","markdown":"https://insights.sbomify.com/MAL-2026-4193/index.md","name":"MAL-2026-4193","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 a postinstall script that uses Node's child_process to execute reconnaissance commands (including `whoami`) and beacon results out via HTTPS.
