Advisory Summary

GHSA-7jx3-jqcp-hhgc is a HIGH (CVSS 8.1) gitpython: unguarded git read-tree option vulnerability (CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')) affecting Duplicate Advisory libraries in the PyPI ecosystem. The issue involves gitpython: unguarded git read-tree option forwarding in indexfile.from_tree/reset/merge_tree enables arbitrary file overwrite. Remediation is available in the latest vendor maintenance releases.

How to Fix GHSA-7jx3-jqcp-hhgc

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

gitpython fixed: Latest secure release 
pip install gitpython>=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: 

pip show gitpython

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-7jx3-jqcp-hhgc, inspect your installed packages using pip:

pip show gitpython

Analyze the terminal output to locate any version of Duplicate Advisory 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 pip show gitpython command checks currently installed packages in your active Python environment.

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 Duplicate Advisory, 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

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-4gmw-gg2m-w46p. This link is maintained to preserve external references. ## Original Description GitPython versions before 3.1.58 contain an arbitrary file overwrite vulnerability in IndexFile.from_tree, IndexFile.reset, and IndexFile.merge_tree methods that append caller-influenced treeish strings to git read-tree without option validation or argument separation. Attackers can inject the --index-output option to overwrite arbitrary files with a valid git-index blob, destroying existing file content at attacker-controlled writable paths.
