  • npm v12, releasing in July 2026, introduces breaking changes that default to stricter security settings for installations.
  • 'allowScripts' defaults to off, blocking preinstall, install, and postinstall scripts from dependencies unless explicitly allowed via commands like 'npm approve-scripts'.
  • '--allow-git' defaults to 'none', preventing Git dependencies from resolving unless explicitly allowed, to close a code-execution vulnerability.
  • '--allow-remote' defaults to 'none', blocking dependencies from remote URLs like https tarballs unless explicitly permitted.
  • Preparation involves upgrading to npm 11.16.0+, reviewing warnings, using 'npm approve-scripts' to manage trusted packages, and committing changes to package.json.
