How to Fix GHSA-49mg-94fc-2fx6

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

npm-git-publish fixed: Latest secure release 
npm install npm-git-publish@Latest secure release
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 npm-git-publish

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-49mg-94fc-2fx6, inspect your project dependencies using npm:

npm ls npm-git-publish

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

Note: The npm ls npm-git-publish 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-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Npm git publish, 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

All versions of `npm-git-publish` are vulnerable to Command Injection. The package fails to sanitize input and passes it directly to an `execSync` call, which may allow attackers to execute arbitrary code in the system. The `publish` function is vulnerable through the `gitRemoteUrl` variable. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
