{"id":"UBUNTU-CVE-2026-67322","details":"GitPython before 3.1.52 is vulnerable to environment-variable exfiltration in Repo.clone_from(). The caller-supplied remote URL is passed through Git.polish_url(), which on non-Cygwin platforms calls os.path.expandvars() on the URL before invoking git clone. An attacker who controls the clone URL can embed $NAME or ${NAME} tokens that are expanded to the values of the hosting process's environment variables (e.g., AWS_SECRET_ACCESS_KEY or GITHUB_TOKEN). The resulting URL, now containing the secret, is transmitted over the network to an attacker-controlled host during the clone attempt, disclosing the secret.","modified":"2026-08-06T00:23:23Z","published":"2026-08-01T13:17:00Z","upstream":["CVE-2026-67322"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-67322"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-67322"},{"type":"REPORT","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-rwj8-pgh3-r573"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/gitpython-before-environment-variable-exfiltration-via-clone-from"}],"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"}]}],"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","0.3.2~RC1-3ubuntu0.1~esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"python-git","binary_version":"0.3.2~RC1-3ubuntu0.1~esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67322.json"}},{"package":{"name":"python-git","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/python-git?arch=source&distro=esm-apps-legacy%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.1+git137-gc8b8379-1","1.0.1+git137-gc8b8379-2","1.0.1+git137-gc8b8379-2.1","1.0.1+git137-gc8b8379-2.1ubuntu0.1~esm1","1.0.1+git137-gc8b8379-2.1ubuntu0.1~esm2","1.0.1+git137-gc8b8379-2.1ubuntu0.1~esm4"],"ecosystem_specific":{"binaries":[{"binary_name":"python-git","binary_version":"1.0.1+git137-gc8b8379-2.1ubuntu0.1~esm4"},{"binary_version":"1.0.1+git137-gc8b8379-2.1ubuntu0.1~esm4","binary_name":"python3-git"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67322.json"}},{"package":{"name":"python-git","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/python-git?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.5-1","2.1.6-1","2.1.7-1","2.1.8-1","2.1.8-1ubuntu0.1~esm1","2.1.8-1ubuntu0.1~esm2","2.1.8-1ubuntu0.1~esm4"],"ecosystem_specific":{"binaries":[{"binary_name":"python-git","binary_version":"2.1.8-1ubuntu0.1~esm4"},{"binary_version":"2.1.8-1ubuntu0.1~esm4","binary_name":"python3-git"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67322.json"}},{"package":{"name":"python-git","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/python-git?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.11-1","3.0.4-1","3.0.5-1","3.0.7-1","3.0.7-1ubuntu0.1~esm1","3.0.7-1ubuntu0.1~esm2","3.0.7-1ubuntu0.1~esm4"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-git","binary_version":"3.0.7-1ubuntu0.1~esm4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67322.json"}},{"package":{"name":"python-git","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/python-git?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.14-1","3.1.23-1","3.1.24-1","3.1.24-1ubuntu0.1~esm1","3.1.24-1ubuntu0.1~esm2","3.1.24-1ubuntu0.1~esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.24-1ubuntu0.1~esm3","binary_name":"python3-git"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67322.json"}},{"package":{"name":"python-git","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/python-git?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.30-1","3.1.37-1","3.1.37-3","3.1.37-3ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"python3-git","binary_version":"3.1.37-3ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67322.json"}},{"package":{"name":"python-git","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/python-git?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.44-1","3.1.45-1","3.1.46-1","3.1.46-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.46-1ubuntu0.1~esm1","binary_name":"python3-git"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-67322.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
