{"id":"DEBIAN-CVE-2026-76220","details":"GitPython before 3.1.58 contains a command execution vulnerability in the check_unsafe_options guard that can be bypassed by combining a single-character kwarg with split_single_char_options=False. Attackers can supply a crafted kwargs dictionary to guarded methods like clone_from to emit a joined token parsed as --upload-pack, enabling arbitrary OS command execution at default allow_unsafe_options=False.","modified":"2026-09-04T08:47:28.177163574Z","published":"2026-08-19T14:17:48.323Z","upstream":["CVE-2026-76220"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-76220"}],"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"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-76220.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"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-76220.json"}},{"package":{"name":"python-git","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-git?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.61-1"}]}],"versions":["3.1.44-1","3.1.45-1","3.1.46-1","3.1.50-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-76220.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
