Upgrade github.com/github/git-sizer to 1.4.0
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 github.com/github/git-sizer

How to Check if You Are Affected

To determine whether your application is affected by GHSA-57q7-rxqq-7vgp, inspect your project dependencies for Github.com/github/git sizer:

inspect dependencies for github.com/github/git-sizer

Analyze the terminal output to locate any version of Github.com/github/git sizer in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.0), 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 General Security Weakness. In Github.com/github/git sizer, 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 On Windows, if `git-sizer` is run against a non-bare repository, and that repository has an executable called `git.exe`, `git.bat`, etc., then that executable might be run by `git-sizer` rather than the system `git` executable. An attacker could try to use social engineering to get a victim to run `git-sizer` against a hostile repository and thereby get the victim to run arbitrary code. On Linux or other Unix-derived platforms, a similar problem could occur if the user's `PATH` has the current directory before the path to the standard `git` executable, but this is would be a very unusual configuration that has been known for decades to lead to all kinds of security problems. ### Patches Users should update to git-sizer v1.4.0 ### Workarounds If you are on Windows, then either * Don't run `git-sizer` against a repository that might contain hostile code, or, if you must… * Run `git-sizer` against a bare clone of the hostile repository, or, if that is not possible… * Make sure that the hostile repository doesn't have an executable in its top-level directory before running `git-sizer`. If you are on Linux or other Unix-based system, then (for myriad reasons!) don't add the current directory to your `PATH`. ### References * [Command PATH security in Go](https://blog.golang.org/path-security) ### For more information If you have any questions or comments about this advisory: * Open an issue in [the `git-sizer` project](https://github.com/github/git-sizer). * Email us at [GitHub support](mailto:support@github.com).
