{"id":"CVE-2026-114145","published":"2026-10-21T21:17:57.250","lastModified":"2026-10-23T15:17:25.770","description":"GitPython is a python library used to interact with Git repositories. Prior to 3.2.1, create_submodule() in git/objects/submodule/base.py accepts an attacker-influenced submodule path such as .git/hooks and invokes _clone_repo() before safely rejecting the destination. In 3.1.x, _validate_repo_path() does not exist and the call succeeds silently, while in 3.2.0 and later affected revisions the check in git/index/base.py raises ValueError only after the clone has written to disk and does not remove the planted file. An attacker-controlled submodule can therefore place an executable post-checkout hook that a later Git operation executes. Exploitation requires an application to accept an untrusted submodule path and a clone destination such as .git/hooks that is empty enough for Git to clone into it, which commonly means that default sample hooks are absent. This issue is fixed in version 3.2.1.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-696"],"vendors":[],"products":[],"references":[{"url":"https://github.com/gitpython-developers/GitPython/commit/97eadb888d2f99567e3113f4e455be4ca128f697","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/pull/2264","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/releases/tag/3.2.1","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-83vg-56qc-22m7","tags":[]}],"exploitRefs":[{"url":"https://github.com/gitpython-developers/GitPython/commit/97eadb888d2f99567e3113f4e455be4ca128f697","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/pull/2264","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/releases/tag/3.2.1","tags":[]},{"url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-83vg-56qc-22m7","tags":[]}],"hasPoc":true,"ai":null}
