Dependency Vulnerability Scanning — Securing Your Supply Chain

Your application isn't just the code you write. It's the code you write plus the hundreds (sometimes thousands) of packages you depend on. A typical Next.js project pulls in over 1,000 transitive dependencies. Each one is code written by someone else that runs with the same privileges as your own code.

When one of those dependencies has a vulnerability, your application has a vulnerability — even if your code is perfect. This is the supply chain problem, and it's one of the fastest-growing attack vectors in software.

The Scale of the Problem

The numbers paint a clear picture:

• The average JavaScript project has 683 transitive dependencies
• In 2023, over 26,000 vulnerabilities were disclosed in open-source packages
• The median time between a vulnerability being introduced
