"lint": "cross-env NODE_ENV=development eslint . --ext .js,.jsx,.ts,.tsx",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.
