Express.js Security Audit: A Milestone Achievement

By Express Technical Committee
22 Oct 2024

We are thrilled to announce the successful completion of a comprehensive security audit for Express.js, conducted by Ada Logics and facilitated by OSTIF. This extensive review of our framework and its core components marks a significant milestone in our commitment to ensuring the security and reliability of Express.js for our community.

A Collaborative Effort

This audit was made possible through the collaboration between the Express Security Working Group, Ada Logics, OSTIF, and the OpenJS Foundation. Our focus was on thoroughly evaluating the Express.js codebase, including its dependencies and core libraries. The primary goal was to identify any potential security vulnerabilities and to strengthen the overall security posture of the framework.

Key Highlights of the Audit

A Closer Look at the Findings

The audit identified several vulnerabilities, including potential Cross-Site Scripting (XSS) risks and a Denial of Service (DoS) vulnerability in the body-parser middleware. Here are the key CVEs reported:

Each of these vulnerabilities was promptly addressed by our dedicated security triage team, ensuring that users remain protected against known threats.

A Commitment to Transparency and Security

At Express, security is a top priority, and we believe in the importance of transparency when it comes to vulnerabilities and their resolution. This audit not only highlights our proactive approach but also reinforces our ongoing commitment to building a secure web framework for all.

We strongly recommend all users update to the latest versions of the affected packages to benefit from the recent security fixes. For more information on the patches and how to upgrade, please refer to our September 2024 Security Release announcement.

A Word of Thanks

This audit would not have been possible without the efforts and expertise of many individuals and organizations. We want to extend our gratitude to:

Together, we’ve made Express.js stronger, more resilient, and ready for the challenges ahead. We look forward to continuing to serve our community with a focus on excellence and security.

Thank you for being a part of this journey with us!
