How to Fix CVE-2022-25648

To remediate this vulnerability, upgrade all affected 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.

git fixed: 1.11.0 
Upgrade git to 1.11.0
Verify Direct and Transitive Dependencies

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

inspect dependencies for git

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-25648, inspect your project dependencies for Git:

inspect dependencies for git

Analyze the terminal output to locate any version of Git in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.11.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. In 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 prior to v1.11.0 is vulnerable to Command Injection via git argument injection. When calling the `fetch(remote = 'origin', opts = {})` function, the remote parameter is passed to the `git fetch` subcommand in a way such that additional flags can be set. The additional flags can be used to perform a command injection.
