Starting today, the npm registry will begin removing README content from package version metadata to reduce the size of package packuments, and improve the performance of the registry and package managers, including the npm cli.

A packument is the top-level package document that lists the set of manifests for available versions for a package. Users can observe the packuments using tools such as pacote.

On September 27, 2023, we began blocking npm package publishes with differing name or version fields between the manifest and tarball package.json. This blocking protects against obfuscation. The different fields in the manifests have been assessed from a risk-based perspective. We will continue to analyze for other mismatches that can be blocked that won’t have adverse effects on the ecosystem. If a package is blocked, a user may receive an error message similar to “Package ‘version’ is “1.0.4”. It should match “1.0.3” from “package.json” in packaged tarball. Make all changes to package.json before packaging a tarball to publish.” In addition, a new tool, npm pkg fix, can help users fix any validation errors from the registry when they attempt to publish a package.

npm provenance is now generally available.

npm packages built on a supported cloud CI/CD system can publish with provenance. Today this includes GitHub Actions and GitLab CI/CD.

Publishing with provenance verifiably links the package back to its source repository and build instructions. Provenance is restricted to public packages and public source repositories only.

npm will check the linked source commit and repository when you view a package's provenance information on npmjs.com. If the linked source commit or repository cannot be found, an error displays at the top of the page and alongside the provenance information to let you know that provenance for this package can no longer be established. This can happen when a repository is deleted or made private.

Once published, packages display provenance on the registry website:

Starting today, publishing with provenance is restricted to public source repositories only. Private source repositories are no longer supported for use with provenance for public packages.

As announced on July 11, 2023: npm will verify the linked source commit and repository when users view a package's provenance information on npmjs.com. If the linked source commit or repository cannot be found, an error will be displayed. This can occur if a repository is deleted or if it is made private.

Today we are making further improvements to granular access tokens in npm.

Highlights of this update are

  • Custom Expiration Times: You can now create granular access tokens with custom expiration times, allowing for durations that span multiple years.
  • Increased Token Limit: We have expanded the maximum limit for granular access tokens creation to 1000. This enables maintainers with a large amount of packages to secure their publishing workflows more efficiently.

We recommend using granular access tokens with least privileges (for example one token per package) for automating your publishing and org management activities.

Starting today, Dependabot will be able to auto-dismiss npm alerts that have limited impact (e.g. long-running tests) or are unlikely to be exploitable. With this ship, Dependabot will cut false positives and reduce alert fatigue substantially.

On-by-default for public repositories, and opt-in for private repositories, this feature will result in 15% of low impact npm alerts being auto-dismissed moving forward – so you can focus on the alerts that matter, without worrying about the ones that don’t.

What’s changing?

When the feature is enabled, Dependabot will auto-dismiss certain types of vulnerabilities that are found in npm dependencies used in development (npm devDependency alerts with scope:development). This feature will help you proactively filter out false positives on development-scoped (non-production or runtime) alerts without compromising on high risk devDependency alerts.

Frequently asked questions

Why is GitHub making this change?

At GitHub, we’ve been thinking deeply about how to responsibly address long-running issues around alert fatigue and false positives. Rather than over-indexing on one criterion like reachability or dependency scope, we believe that a responsibly-designed solution should be able to detect and reason on a rich set of complex, contextual alert metadata.

That’s why, moving forward, we’re releasing a series of ships powered by an underlying, all-new, flexible and powerful alert rules engine. Today’s ship, our first application, leverages GitHub-curated vulnerability patterns to help proactively filter out false positive alerts.

Why auto-dismissal, rather than purely suppressing these alerts?

Auto-dismissing ensures any ignored alerts are 1) able to be reintroduced if alert metadata changes, 2) caught by existing reporting systems and workflows, and 3) extensible as a whole to future rules-based actions, where Dependabot can decision on subsets of alerts and do things like reopen for patch, open a Dependabot pull request, or even auto-merge if very risky.

How does GitHub identify and detect low impact alerts?

Auto-dismissed alerts match GitHub-curated vulnerability patterns. These patterns take into account contextual information about how you’re using the dependency and the level of risk they may pose to your repository. To learn more, see our documentation on covered classes of vulnerabilities.

How will this activity be reported?

Auto-dismissal activity is supported across webhooks, REST, GraphQL, and the audit log for Dependabot alerts. In addition, you can review your closed alert list with the resolution:auto-dismissed filter.

How will this experience look and feel?

Alerts identified as false positives will be automatically dismissed without a notification or new pull request, and appear as special timeline event. As these alerts are closed, you’ll still be able to review any auto-dismissed alerts with the resolution:auto-dismissed filter.

How do I reopen an automatically dismissed alert?

Like any manually dismissed alert, you can reopen an auto-dismissed alert from the alert list view or details page. This specific alert won’t be auto-dismissed again.

What happens if alert metadata changes or advisory information is withdrawn?

Dependabot recognizes and immediately responds to any changes to metadata which void auto-dismissal logic. For example, if you change the dependency scope and the alert no longer meets the criteria to be auto-dismissed, the alert will automatically reopen.

How can I enable or disable the feature?

This feature is on-by-default for public repositories and opt-in for private repositories. Repository admins can opt in or out from your Dependabot alerts settings in the Code Security page.

Is this feature available for enterprise?

Yes! In addition to all free repositories, this feature will ship immediately to GHEC and to GHES in version 3.10.

What’s next?

Next, we’ll expose our underlying engine – which enables Dependabot to perform actions based on a rich set of contextual alert metadata – so you can write your own custom rules to better manage your alerts, too.

npm packages built on a cloud CI/CD system (like GitHub Actions) can now publish with provenance, meaning the package has verifiable links back to its source code and build instructions.

The cloud CI/CD system securely communicates this information by sending provenance information in a signed OIDC JWT to Sigstore's public-good servers, which returns a signing certificate that is sent to the registry along with your built package.

Here's an example of how to do a build with provenance in a GitHub Actions workflow:

name: Publish Package to npmjs
on:
 release:
   types: [created]
jobs:
 build:
   runs-on: ubuntu-latest
   permissions:
     contents: read
     id-token: write
   steps:
     - uses: actions/checkout@v3
     - uses: actions/setup-node@v3
       with:
         node-version: '18.x'
         registry-url: 'https://registry.npmjs.org'
     - run: npm install -g npm
     - run: npm ci
     - run: npm publish --provenance --access public
       env:
         NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}

Once published, packages display provenance on the registry website:

Dependencies with provenance can also be verified from the command line with npm audit signatures.

Today we are making the granular access token feature on npm generally available.

Granular access token, allows you to:

  • Restrict token access to specific packages and/or scopes
  • Grant tokens access to specific organizations for org and user management
  • Set a token expiration date
  • Limit token access based on IP address ranges
  • Select between read and/or write access for the token

We recommend using granular access tokens with least privileges for automating your publishing and org management activities. You can allow your package to be published without 2FA using granular access tokens from your trusted CI/CD systems. Additionally, you can also configure your package to require 2FA when publishing from a local machine to defend against account hijacking.

GitHub Security was recently notified about a caching issue affecting npm. This bug had been present since 2016 and sporadically caused npm maintainers to be re-invited upon removal from packages or organizations. Our Security team investigated potential instances of the issue and believe this bug only occurred if a user was removed, followed shortly by the addition of a different member. This bug affected npm-cli version 6 and above, and was fixed in version 7+.

Out of an abundance of caution, we are recommending all npm users review the maintainers of their projects and organizations for any discrepancies that may be a result of this bug and remove any unexpected members. Please feel free to reach out to us with any additional questions or concerns through the following contact form: https://www.npmjs.com/support.

You can now view the content of a package with the updated code explorer directly on the npmjs.com portal. We have improved the reliability, performance and have now made this feature available for free. You no more need to download a package to view its content. With this feature, you can easily scrutinise packages to make sure it is safe for use in your application. The code explorer provides syntax highlighting for .js, .ts, .md, .json and other commonly used file types in npm packages. You can also view the content of any previous version of a package.

Start by exploring the npm package.

You can now create access tokens with limited scope using the new granular access tokens functionality in npm. With granular access tokens, you can:

  • Restrict which packages and/or scopes a token has access to
  • Grant tokens access to specific organizations for user management
  • Set a token expiration date
  • Limit token access based on IP address ranges
  • Select between read and/or write access

Tokens with least privileges protects your npm packages from accidental or malicious misuse of your token. These tokens also allow you to manage your npm org and teams from a CI/CD pipeline. Granular access tokens are specifically built for automation and do not require 2FA. We recommend using granular access tokens with least privileges while you automate publishing and org management activities.

Starting today, two-factor authentication (2FA) will be enforced for maintainers of all high-impact npm packages. A package is marked as a high impact package when they have more than 1 million weekly downloads or have more than 500 dependents. Maintainers of such packages will be notified 15 days in advance to enroll for 2FA.

To learn more about configuring 2FA, see Configuring two-factor authentication.
To learn more about 2FA in general, see About two-factor authentication.
For questions and comments, open a discussion in our feedback repository.
