CVE-2026-42215
GitPython: Command injection via Git options bypass
CVSS Score

EPSS Percentile
0th
GitPython is a python library used to interact with Git repositories. From version 3.1.30 to before version 3.1.47, GitPython blocks dangerous Git options such as --upload-pack and --receive-pack by default, but the equivalent Python kwargs upload_pack and receive_pack bypass that check. If an application passes attacker-controlled kwargs into Repo.clone_from(), Remote.fetch(), Remote.pull(), or Remote.push(), this leads to arbitrary command execution even when allow_unsafe_options is left at its default value of False. This issue has been patched in version 3.1.47.
