How to Fix GHSA-5vj8-3v2h-h38v

To remediate this vulnerability, upgrade all affected Next dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

next fixed: 5.1.0 
npm install next@5.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls next

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-5vj8-3v2h-h38v, inspect your project dependencies using npm:

npm ls next

Analyze the terminal output to locate any version of Next in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.1.0), your application is affected.

Note: The npm ls next command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Next, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of `next` prior to 5.1.0 are vulnerable to Remote Code Execution. The `/path:` route fails to properly sanitize input and passes it to a `require()` call. This allows attackers to execute JavaScript code on the server. Note that prior version 0.9.9 package `next` npm package hosted a different utility (0.4.1 being the latest version of that codebase), and this advisory does not apply to those versions. ## Recommendation Upgrade to version 5.1.0.
