## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-wvpp-8hx9-p66j. This link is maintained to preserve external references.

## Original Description
GitPython before 3.1.58 contains a command execution vulnerability in the check_unsafe_options guard that can be bypassed by combining a single-character kwarg with split_single_char_options=False. Attackers can supply a crafted kwargs dictionary to guarded methods like clone_from to emit a joined token parsed as --upload-pack, enabling arbitrary OS command execution at default allow_unsafe_options=False.

## Affected packages

- `gitpython <= 3.1.57`

## Remediation

Refer to the advisory for the patched release.
