## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-5xxx-qhh7-9287. This link is maintained to preserve external references.

## Original Description
GitPython versions before 3.1.59 contain an incomplete denylist in the unsafe_git_revision_options guard that omits --contents and -S options, allowing attackers to read arbitrary files by passing these options to Repo.blame(). Attackers can supply revision values like --contents=/etc/passwd to leak file contents through the blame result returned to the caller.

## Affected packages

- `gitpython <= 3.1.58`

## Remediation

Refer to the advisory for the patched release.
