How to Fix CVE-2022-24433

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

simple-git fixed: 3.3.0 
npm install simple-git@3.3.0
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 simple-git

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-24433, inspect your project dependencies using npm:

npm ls simple-git

Analyze the terminal output to locate any version of Simple git in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.0), your application is affected.

Note: The npm ls simple-git 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Simple git, 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

The package simple-git before 3.3.0 is vulnerable to Command Injection via argument injection. When calling the .fetch(remote, branch, handlerFn) function, both the remote and branch parameters are passed to the git fetch subcommand. By injecting some git options, it was possible to get arbitrary command execution.
