## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-v396-v7q4-x2qj. This link is maintained to preserve external references.

## Original Description

GitPython 3.1.50 fails to recognize joined short-option forms such as -u<value> (the short form of --upload-pack=<value>) when enforcing its default unsafe-option gate. When an application passes attacker-influenced clone options into Repo.clone_from(..., multi_options=..., allow_unsafe_options=False), an attacker can supply -u<helper> to bypass the gate that blocks --upload-pack/-u, causing Git to execute the specified helper command during clone. Fixed in 3.1.51.

## Affected packages

- `gitpython = 3.1.50`

## Remediation

Refer to the advisory for the patched release.
