{"id":"DEBIAN-CVE-2026-110857","details":"GitPython before 3.2.0 contains a remote code execution vulnerability that allows attackers to run commands because Git.ls_remote forwards URLs without check_unsafe_protocols validation. Attackers can supply ext:: remote-helper URLs to execute commands when git permits the ext transport, while merge_base and IndexFile.move also accept unguarded option injection.","modified":"2026-10-15T12:00:06.875211772Z","published":"2026-10-14T23:17:26.903Z","upstream":["CVE-2026-110857"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110857"}],"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-2026-110857.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-2026-110857.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-2026-110857.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
