CVE-2023-40267Network attack vector

Remote code execution via unchecked clone options

Published Aug 11, 2023 · Updated Nov 3, 2025

Command injection in GitPython before 3.1.32 allows remote attackers to execute code through unsafe options passed to clone operations. The Repo._clone method validates multi_options but forwards keyword options such as upload-pack and config to Git without the same unsafe-option check. Exploitation requires an application to pass attacker-controlled clone options; injected commands run with that application process's privileges.
