Security Policies and Procedures

This document outlines security procedures and general policies for the Express project.

Reporting a Bug

The Express team and community take all security bugs in Express seriously. Thank you for improving the security of Express. We appreciate your efforts and responsible disclosure and will make every effort to acknowledge your contributions.

Report security bugs by emailing the lead maintainer in the file.

To ensure the timely response to your report, please ensure that the entirety of the report is contained within the email body and not solely behind a web link or an attachment.

The lead maintainer will acknowledge your email within 48 hours, and will send a more detailed response within 48 hours indicating the next steps in handling your report. After the initial reply to your report, the security team will endeavor to keep you informed of the progress towards a fix and full announcement, and may ask for additional information or guidance.

Report security bugs in third-party modules to the person or team maintaining the module.

Pre-release Versions

Alpha and Beta releases are unstable and not suitable for production use. Vulnerabilities found in pre-releases should be reported according to the Reporting a Bug section. Due to the unstable nature of the branch it is not guaranteed that any fixes will be released in the next pre-release.

Disclosure Policy

When the security team receives a security bug report, they will assign it to a primary handler. This person will coordinate the fix and release process, involving the following steps:

  • Confirm the problem and determine the affected versions.
  • Audit code to find any potential similar problems.
  • Prepare fixes for all releases still under maintenance. These fixes will be released as fast as possible to npm.

The Express Threat Model

We are currently working on a new version of the security model, the most updated version can be found here
