## Overview

## 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This advisory has been withdrawn because it is a duplicate of GHSA-4gmw-gg2m-w46p.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.

## Affected packages

- `gitpython <= 3.1.57`

## Remediation

Refer to the advisory for the patched release.
