install-pip-setup-exec

CRITICAL

setup.py executes code at install time

package/dist/cli.js:5401


# Full setup (includes embedding model download):
npx ca setup

Why was this flagged?

This setup.py calls subprocess, os.system, exec, or eval during package installation. Legitimate packages rarely need to execute arbitrary commands at install time. This pattern is commonly used by malicious packages to download and run payloads, exfiltrate environment variables, or establish persistence. Rated CRITICAL because it runs with the installer's full permissions.

install-npm-postinstall

CRITICAL

npm lifecycle script — runs automatically on install

package/package.json:36

  "scripts": {
    "postinstall": "node scripts/postinstall.mjs",
    "prebuild": "tsx scripts/extract-changelog.ts",

Why was this flagged?

npm lifecycle scripts like postinstall run automatically during package installation with no user interaction required. This is the #1 attack vector for malicious npm packages — attackers embed data theft or backdoor installation in these hooks. Rated CRITICAL because code executes before the developer can review it.
