How to check if your Next.js or Node.js version is vulnerable

Check your project lockfile

Your project uses a lockfile like package-lock.json to record the exact version of every dependency you install. While your package.json might show a version range, the lockfile contains the specific patch version currently running in your environment. Open this file to find the version numbers for Next.js and other critical libraries before you compare them against security advisories.

Search vulnerability databases

Once you have your version numbers, search for them in the GitHub Advisory Database or on OSV.dev. These sites list known security flaws and specify which versions contain a fix, so you can see if your current setup is at risk. Most advisories follow semantic versioning, which makes it easier to tell if a specific patch will resolve the issue.

Run automated audit tools

Run built-in commands like npm audit to scan your dependencies for known vulnerabilities automatically. These tools compare your lockfile against a database of reports and suggest the necessary updates to keep your application secure. If you use other languages, tools like pip-audit or composer audit provide similar checks for your project.

Verify your runtime version

The version of Node.js running on your server or local machine also requires regular checks for security updates. Find your current version by running node -v in your terminal, then compare it to the support dates on endoflife.date. Locaas provides a free repository scan that monitors these versions and alerts you when a new patch is available.

What to do

• Open your lockfile to find exact versions
• Search OSV.dev or GitHub for your specific version
• Run npm audit in your terminal to find risks
• Check your Node.js version with the node -v command.
