CVE-2026-110855

CVE-2026-110855 · GitPython before 3.2.0 Environment Variable Disclosure via .gitmodules Submodule Name

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
