Advisory Summary

GHSA-4vpg-pfj8-m33q is a HIGH (CVSS 8.4) gitpython: command injection vulnerability (CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection')) affecting Duplicate Advisory libraries in the PyPI ecosystem. The issue involves gitpython: command injection via unguarded git options in `repo.archive()`, `git.ls_remote()`, and arbitrary file overwrite via `repo.iter_commits()` / `repo.blame()`. Remediation is available in the latest vendor maintenance releases.

How to Fix GHSA-4vpg-pfj8-m33q

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-4vpg-pfj8-m33q, 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-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. 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## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-956x-8gvw-wg5v. This link is maintained to preserve external references. ## Original Description GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution). Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output=<path> can cause Git to open and truncate an arbitrary file. Exploitation requires an application that passes attacker-controlled arguments to these methods.
