CVE-2026-78677

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.

Summary		(es) GitPython anterior a la versión 3.1.59 omite --separate-git-dir de unsafe_git_clone_options, permitiendo a los atacantes crear directorios git arbitrarios fuera del destino de clonación previsto. Los atacantes pueden pasar un parámetro separate_git_dir a Repo.clone_from() o Repo.clone() para redirigir los metadatos del repositorio a una ruta del sistema de archivos controlada por el atacante, lo que permite la creación arbitraria de directorios y la posible ejecución de hooks.
