TL;DR
npm v12, scheduled for release in July 2026, will enforce new default security policies that block script execution and dependency resolution unless explicitly permitted. Users are advised to prepare by reviewing warnings in npm 11.16.0+.
npm v12, scheduled for release in July 2026, will introduce default security restrictions that block script execution and remote dependency resolution unless explicitly enabled by users. These changes significantly alter current behaviors, requiring developers to proactively approve trusted scripts and dependencies to avoid disruptions.
The upcoming npm v12 will change default behaviors by disabling automatic execution of preinstall, install, and postinstall scripts from dependencies, including native node-gyp builds, unless explicitly permitted by the user. This is achieved through the new –allow-scripts-pending mechanism, which requires users to review and approve scripts before they run. Additionally, npm will no longer resolve Git dependencies or dependencies from remote URLs unless explicitly allowed via –allow-git and –allow-remote flags, respectively.
These changes are available behind warnings in npm 11.16.0 and later versions, giving users time to prepare. To adapt, developers are advised to run ‘npm approve-scripts –allow-scripts-pending’ to review and approve trusted scripts, then commit the updated package.json. The default restrictions aim to improve security by preventing unintended code execution and dependency resolution vulnerabilities.
Security Enhancements Drive npm v12 Defaults
These default restrictions in npm v12 are designed to bolster security by preventing automatic script execution and remote dependency resolution, which have historically been vectors for malicious code. Developers relying on scripts or remote dependencies will need to explicitly authorize these actions, reducing the risk of supply chain attacks and unintentional code execution.

Previous npm Security and Version Updates
Prior to v12, npm allowed automatic execution of dependency scripts and resolution of dependencies from remote URLs and Git repositories by default. These behaviors, while convenient, posed security risks. The move to restrict these by default has been discussed since early 2026, with warnings available since npm 11.16.0. The upcoming v12 aims to formalize these security measures, aligning npm with best practices for dependency safety.
“The new default restrictions in npm v12 are a significant step toward reducing supply chain vulnerabilities.”

Details on Transition and User Impact
While the core changes are confirmed, it remains unclear how widely early warnings and preparatory tools will mitigate potential disruptions for complex projects. The exact process for managing large, legacy codebases that rely heavily on scripts or remote dependencies is still being clarified by the npm team.

Preparing for npm v12 Release and Transition
Developers should update to npm 11.16.0 or later to review warnings and run ‘npm approve-scripts –allow-scripts-pending’ for trusted packages. Monitoring npm’s official documentation and community discussions will be essential as the July 2026 release approaches. Post-release, users will need to review and approve scripts and dependencies explicitly to maintain functionality.

Key Questions
Will existing projects break after upgrading to npm v12?
Projects that rely on automatic script execution or remote dependencies may encounter issues unless scripts and dependencies are explicitly approved beforehand.
How can I prepare my project for these changes?
Update to npm 11.16.0 or later, review warnings, and use ‘npm approve-scripts’ to authorize trusted scripts and dependencies before upgrading to v12.
Are there any exceptions or overrides available?
Yes, users can explicitly allow scripts and dependencies via command-line flags such as –allow-scripts-pending, –allow-git, and –allow-remote, but these must be set intentionally.
When exactly will npm v12 be released?
The release is targeted for July 2026, with ongoing preparations and warnings available in current npm versions.
What security benefits do these changes offer?
The restrictions reduce the risk of malicious code execution through dependency scripts and remote dependencies, strengthening supply chain security.
