Duplicate Advisory: clone_from()/clone() omit --separate-git-dir from unsafe_git_clone_options, enabling arbitrary git-directory creation outside the destination

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-8mcc-hrx5-hvxc. This link is maintained to preserve external references.

Original Description

GitPython before 3.1.59 omits --separate-git-dir from unsafe_git_clone_options, allowing attackers to create arbitrary git directories outside the intended clone destination. Attackers can pass a separate_git_dir parameter to Repo.clone_from() or Repo.clone() to redirect repository metadata to an attacker-controlled filesystem path, enabling arbitrary directory creation and potential hook execution.
