Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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-2026-5718/ (Markdown: https://insights.sbomify.com/MAL-2026-5718/index.md)","id":"MAL-2026-5718","markdown":"https://insights.sbomify.com/MAL-2026-5718/index.md","name":"MAL-2026-5718","record":{"aliases":["GHSA-9j3j-4vjh-6h88"],"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 preinstall hook (`\"preinstall\": \"node index.js\"`) that auto-executes on `npm install`. index.js issues an HTTP GET to the hardcoded bare IP `10.107.121.85:8000` at path `/ping_472839_ctf`. The unique token in the URL path makes the request itself the exfiltrated signal — it confirms to the operator of that endpoint that the package executed inside the installer's environment, leaking the installer's source IP and the fact that code execution succeeded. The package advertises no functionality that would justify a phone-home, and the destination is a private-range IP rather than any documented service. This is the canonical dependency-confusion / CTF probe shape, and the same mechanism would deliver any payload an attacker placed in index.js.\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.
