CRITICALnpm lifecycle script — runs automatically on install
repo/packages/vestige-mcp-npm/package.json:10
"scripts": {
"postinstall": "node scripts/postinstall.js"
},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.
