CRITICALnpm lifecycle script — runs automatically on install
repo/package.json:14
"rebuild": "electron-rebuild -f -w better-sqlite3",
"postinstall": "pnpm run rebuild",
"e2e": "pnpm package && pnpm e2e:prebuilt",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.
