{"id":"UBUNTU-CVE-2026-42215","details":"GitPython is a python library used to interact with Git repositories. From version 3.1.30 to before version 3.1.47, GitPython blocks dangerous Git options such as --upload-pack and --receive-pack by default, but the equivalent Python kwargs upload_pack and receive_pack bypass that check. If an application passes attacker-controlled kwargs into Repo.clone_from(), Remote.fetch(), Remote.pull(), or Remote.push(), this leads to arbitrary command execution even when allow_unsafe_options is left at its default value of False. This issue has been patched in version 3.1.47.","modified":"2026-05-27T10:16:46.678956332Z","published":"2026-05-07T19:16:00Z","related":["USN-8303-1"],"upstream":["CVE-2026-42215"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-42215"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-42215"},{"type":"REPORT","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-rpm5-65cw-6hj4"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8303-1"}],"affected":[{"package":{"name":"python-git","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/python-git?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.3.2~RC1-3ubuntu0.1~esm3"}]}],"versions":["0.3.2~RC1-2","0.3.2~RC1-3","0.3.2~RC1-3ubuntu0.1~esm1","0.3.2~RC1-3ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.3.2~RC1-3ubuntu0.1~esm3","binary_name":"python-git"}],"availability":"Available
