Security release process

The security release process covers the steps required to plan/implement a security release. This document is copied into the description of the Next Security Release and used to track progress on the release. It contains TEXT LIKE THIS which will be replaced during the release process with the information described.

Security release stewards

For each security release, a security steward will take ownership for coordinating the steps outlined in this process. Security stewards are nominated through an issue in the TSC repository and approved through the regular TSC consensus process. Once approved, they are given access to all of the resources needed to carry out the steps listed in the process as outlined in security steward on/off boarding.

The current security stewards are documented in the main Node.js README.md.

Planning

• 1. Generating Next Security Release PR

  • Run git node security --start inside security-release repository.
  • This command generates a new vulnerabilities.json file with HackerOne reports chosen to be released in the security-release/next-security-release folder.
  • It also creates the pull request used to manage the security release.

• 2. Review of Reports:

  • Reports can be added or removed using the following commands:
    • Use the "summary" feature in HackerOne. Example 2038134
    • git node security --add-report=report_id
    • git node security --remove-report=report_id
  • Ensure to ping the Node.js TSC team for review of the PRs prior to the release date.
    • Adding individuals with expertise in the report topic is also a viable option if communicated properly with nodejs/security and TSC.

• 3. Assigning Severity and Writing Team Summary:

  • Assign a severity and write a team summary on HackerOne for the reports chosen in the vulnerabilities.json.
  • Run git node security --sync to update severity and summary in vulnerabilities.json.

• 4. Requesting CVEs:

  • Request CVEs for the reports with git node security --request-cve.
  • Make sure to have a green CI before requesting a CVE.
  • Check if there is a need to issue a CVE for any version that became EOL after the last security release through this issue.

• 5. Choosing or Updating Release Date:

  • Get agreement on the planned date for the release.
  • Use git node security --update-date=YYYY/MM/DD to choose or update the release date.
  • This allows flexibility in postponing the release if needed.

• 6. Get release volunteers:

  • Get volunteers for the upcoming security release on the affected release lines.
  • Make sure to sync nodejs-private (vN.x) branches with nodejs/node.

• 7. Preparing Pre and Post Release Blog Posts:

  • Create a pre-release blog post using git node security --pre-release.
  • Create a post-release blog post using git node security --post-release.

Announcement (one week in advance of the planned release)

• 1. Publish Pre-Release Blog Post:

  • Publish the pre-release blog post on the nodejs/nodejs.org repository.

• 2. Send Pre-Release Announcement:

  • Notify the community about the upcoming security release:

    • git node security --notify-pre-release Except for those noted in the list below, this will create automatically the issues and emails needed for the notifications.
    • docker-node
    • build-wg
    • (Not yet automatic - do this manually) Google Groups
      • Email: notify oss-security@lists.openwall.com
    • (Not yet automatic - do this manually) Post in the nodejs-social channel in the OpenJS slack asking for amplification of the blog post.

    Security release pre-alert:
    
    We will release new versions of <add versions> release lines on or shortly
    after Day Month Date, Year in order to address:
    
    * # high severity issues
    * # moderate severity issues
    
    https://nodejs.org/en/blog/vulnerability/month-year-security-releases/
    

    We specifically ask that collaborators other than the releasers and security steward working on the security release do not tweet or publicize the release until the tweet from Node.js goes out. We have often seen tweets sent out before the release is complete, which may confuse those waiting for the release and take away from the work the releasers have put into shipping the release.

If the security release will only contain an OpenSSL update, consider adding the following to the pre-release announcement:

Since this security release will only include updates for OpenSSL, if you're using
a Node.js version which is part of a distribution that uses a system
installed OpenSSL, this Node.js security update may not concern you, instead,
you may need to update your system OpenSSL libraries. Please check the
security announcements for more information.

Release day

• 1. Lock down the CI:

  • Lock down the CI to prevent public access to the CI machines, ping a member of @nodejs/jenkins-admins.

• 2. Release:

  • Verify the CI is green on all release proposals (test-V8, CITGM, etc).
  • Follow the release process.

• 3. Unlock the CI:

  • Unlock the CI to allow public access to the CI machines, ping a member of @nodejs/jenkins-admins.

• 4. Publish Post-Release Blog Post:

  • Publish the post-release blog post on the nodejs/nodejs.org repository.

• 5. Notify the community:

  • Notify the community that the security release has gone out:
    • Slack: #nodejs-social
    • docker-node
    • build-wg
    • Email: notify Google Groups
      • Forward to oss-security@lists.openwall.com

Post-Release

• 1. Cleanup:
  • git node security --cleanup. This command will:
  • Update next-security-release folder
  • Close all PRs and backports labeled with Security Release.
  • Close HackerOne reports:
    • Close Resolved
    • Request Disclosure
    • Request publication of H1 CVE requests
    • In case the reporter doesn't accept the disclosure follow this process: Remove the original report reference within the reference text box and insert the public URL you would like to be attached to this CVE. Then uncheck the Public Disclosure on HackerOne box at the bottom of the page.
  • PR machine-readable JSON descriptions of the vulnerabilities to the core vulnerability DB.
  • Add yourself as a steward in the Security Release Stewards

Adding a security revert option

Breaking changes are allowed in existing LTS lines in order to fix important security vulnerabilities. When breaking changes are made it is important to provide a command line option that restores the original behaviour.

The existing Node.js codebase supports the command line option --security-revert and has the boilerplate to make additions for a specific CVE easy.

To add an option to revert for a CVE, for example CVE-2024-1234 simply add this line to node_revert.h

  XX(CVE_2024_1234, "CVE-2024-1234", "Description of cve")

This will allow an easy check of whether a reversion has been requested or not.

In JavaScript code you can check:

if (process.REVERT_CVE_2024_1234);

In C/C++ code you can check:

IsReverted(SECURITY_REVERT_CVE_2024_1234)

From the command line a user can request the revert by using the --security-revert option as follows:

node --security-revert=CVE-2024-1234

If there are multiple security reverts then multiple instances of --security-revert can be used. For example:

node --security-revert=CVE-2024-1234 --security-revert=CVE-2024-XXXX

When things go wrong

Incomplete fixes

When a CVE is reported as fixed in a security release and it turns out that the fix was incomplete, a new CVE should be used to cover subsequent fix. This is best practice and avoids confusion that might occur if people believe they have patched the original CVE by updating their Node.js version and then we later change the fixed in value for the CVE.

Updating CVEs

The steps to correct CVE information are:

• Go to the “CVE IDs” section in your program sections (https://hackerone.com/nodejs/cve_requests)
• Click the “Request a CVE ID” button
• Enter the CVE ID that needs to be updated
• Include all the details that need updating within the form
• Submit the request
