Upgrade github.com/cli/cli to 1.2.1
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 github.com/cli/cli

How to Check if You Are Affected

To determine whether your application is affected by GHSA-fqfh-778m-2v32, inspect your project dependencies for Github.com/cli/cli:

inspect dependencies for github.com/cli/cli

Analyze the terminal output to locate any version of Github.com/cli/cli in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.1), 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 General Security Weakness. In Github.com/cli/cli, 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

### Impact GitHub CLI depends on a `git.exe` executable being found in system `%PATH%` on Windows. However, if a malicious `.\git.exe` or `.\git.bat` is found in the current working directory at the time of running `gh`, the malicious command will be invoked instead of the system one. Windows users who run `gh` inside untrusted directories are affected. ### Patches Users should upgrade to GitHub CLI v1.2.1. ### Workarounds Other than avoiding untrusted repositories, there is no workaround. ### References https://github.com/golang/go/issues/38736
