CVE-2026-110855

CVSS 7.1 (high) · published 2026-10-14

GitPython before 3.2.0 contains an information disclosure vulnerability that allows malicious repositories to expand environment variables via separate_git_dir in Repo._clone(), which omits expand_vars=False when calling Git.polish_url(). Attackers can craft a .gitmodules submodule name containing variable syntax so that clone plus submodule_update exposes secrets in .git/modules directory names and DEBUG logs.

Weakness: CWE-200
