CVE-2026-76222Public exploitNetwork attack vector

Arbitrary repository creation via unvalidated submodule name

Published Aug 19, 2026 · Updated Aug 25, 2026

Path traversal in GitPython before 3.1.58 allows remote attackers to create Git repositories outside the clone directory via submodules. sm_name() returns an unchecked .gitmodules section name, and _module_abspath() joins it into .git/modules before _clone_repo() passes the escaped path to directory creation and git clone. Exploitation requires a victim to clone an attacker-controlled repository and initialize its submodules, permitting attacker-controlled content to be written at a chosen filesystem path.
