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-2026-4251/ (Markdown: https://insights.sbomify.com/MAL-2026-4251/index.md)","id":"MAL-2026-4251","markdown":"https://insights.sbomify.com/MAL-2026-4251/index.md","name":"MAL-2026-4251","record":{"aliases":["GHSA-ghw7-gg88-gpmr"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On `npm install`, the package.json `preinstall` hook runs `node telemetry.js`, which performs a DNS lookup against `test-callback.d87u1z3.oast.live` — an Interactsh out-of-band interaction listener. The lookup fires automatically without consent and signals to the operator of the OAST host that the package landed inside the installer's environment, leaking the installer's resolver IP and confirming reachability. The package self-describes as a dependency-confusion proof-of-concept, and the install-time beacon is the attacker-benefit mechanism: it tells the publisher which organizations are vulnerable to namespace confusion against this name. No legitimate purpose exists for an install-time DNS callback to an OAST listener.\n\nAny computer that has this package installed or running should be considered fully compromised.
