How to Fix GHSA-cv3v-7846-6pxm

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

node-git-server fixed: 0.6.1 
npm install node-git-server@0.6.1
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 node-git-server

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-cv3v-7846-6pxm, inspect your project dependencies using npm:

npm ls node-git-server

Analyze the terminal output to locate any version of Node git server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.6.1), your application is affected.

Note: The npm ls node-git-server 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-552: Files or Directories Accessible to External Parties, where the product makes files or directories accessible to unauthorized actors, even though they should not be. In Node git server, 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 `node-git-server` prior to 0.6.1 are vulnerable to Unauthorized File Access. It is possible to access any git repository by using absolute paths, which may allow attackers to access private repositories. ## Recommendation Upgrade to version 0.6.1 or later.
