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-2026-10183/ (Markdown: https://insights.sbomify.com/MAL-2026-10183/index.md)","id":"MAL-2026-10183","markdown":"https://insights.sbomify.com/MAL-2026-10183/index.md","name":"MAL-2026-10183","record":{"aliases":["GHSA-rc5q-c5vp-6g46"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package runs vishu.js as a preinstall lifecycle hook on `npm install`. That script fetches the machine's public IP from api.ipify.org, collects os.hostname() and GitHub Actions / CI environment variables (GITHUB_*), and transmits them as query parameters to a hardcoded webhook.site collector URL over HTTPS. It additionally performs a DNS lookup of a subdomain of the form `ping-\u003chostname\u003e.\u003ccollaborator\u003e.oastify.com`, providing an out-of-band exfiltration channel (Burp Collaborator style) that bypasses HTTP egress filters. There is no legitimate functionality shipped alongside this — the package's only install-time effect is host reconnaissance and beacon-out to attacker-controlled sinks.
