CRITICALnpm lifecycle script — runs automatically on install
repo/package.json:16
"dev": "tsx watch src/index.ts",
"postinstall": "playwright install --with-deps chromium",
"test": "tsx tests/test.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.
