{"id":"DEBIAN-CVE-2026-110855","details":"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.","modified":"2026-10-15T12:00:06.860165637Z","published":"2026-10-14T23:17:26.623Z","upstream":["CVE-2026-110855"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110855"}],"affected":[{"package":{"name":"python-git","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-git?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.30-1","3.1.30-1+deb12u2","3.1.36-1","3.1.37-1","3.1.37-2","3.1.37-3","3.1.44-1","3.1.45-1","3.1.46-1","3.1.50-1","3.1.61-1","3.1.62-1","3.1.62-2","3.1.62-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110855.json"}},{"package":{"name":"python-git","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-git?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.44-1","3.1.45-1","3.1.46-1","3.1.50-1","3.1.61-1","3.1.62-1","3.1.62-2","3.1.62-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110855.json"}},{"package":{"name":"python-git","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-git?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.44-1","3.1.45-1","3.1.46-1","3.1.50-1","3.1.61-1","3.1.62-1","3.1.62-2","3.1.62-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110855.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
