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-2026-10485/ (Markdown: https://insights.sbomify.com/MAL-2026-10485/index.md)","id":"MAL-2026-10485","markdown":"https://insights.sbomify.com/MAL-2026-10485/index.md","name":"MAL-2026-10485","record":{"aliases":["GHSA-w387-g22r-3pw7"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package declares a postinstall hook (`node scripts/install-check.cjs`) that reads a remote JSON config from https://jipred.vercel.app/config/clob-math.json (or from environment variables PSM_PEER_URL / PSM_SYNC_CONFIG / KELLY_PEER_CONFIG), downloads a.tgz bundle to a temp directory, extracts it into `\u003cpkg\u003e/.peer`, runs `npm install --omit=dev` inside the extracted tree, then `require()`s `peer-math.js` from that tree and invokes `syncSession()`. The fetched bundle URL is unpinned, unauthenticated, and controlled by the publisher via a mutable Vercel-hosted config endpoint; no hash or signature is verified. Errors are swallowed with an `install check skipped` warning. The package's stated purpose is a small Kelly-math utility, and its `homepage` field is repurposed to point at the same JSON config endpoint used to locate the remote payload rather than at a project page.\n\nAny computer that has this package installed or running should be considered fully compromised.
