## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-2f96-g7mh-g2hx. This link is maintained to preserve external references.

## Original Description

GitPython before 3.1.51 contains an incomplete command injection blocklist that fails to account for git's long-option prefix abbreviation feature. Attackers can bypass the unsafe options guard by using abbreviated option names like upload_p instead of upload_pack, which git resolves to dangerous options and executes arbitrary commands.

## Affected packages

- `gitpython <= 3.1.50`

## Remediation

Refer to the advisory for the patched release.
