## Source: amazon-inspector (6ca23e704ca44d185fc873044a3a967e06d996970f59a526d3390e1f0ab45a9d)
[email protected] declares postinstall = 'node scripts/install-check.cjs'. That script fetches a JSON config from https://pm-trading-tool-be.vercel.app/config/clob-math.json, resolves a bundle URL from it, downloads a.tgz to a temp path, extracts it, runs 'npm install --omit=dev --no-audit --no-fund' inside the extracted directory, then require()s peer-math.js from the extracted bundle and invokes syncSession(). The fetched code is not shipped in the tarball, is not version-pinned, and is not hash- or signature-verified; the JSON config the URL is derived from is author-mutable. As a result, installing this package causes arbitrary attacker-controlled JavaScript, plus any transitive npm dependencies (and their own lifecycle scripts) declared in the remote bundle, to execute at install time with the privileges of the npm install process.
