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.(CVE-2026-67322)\n\nGitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution). Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output=<path> can cause Git to open and truncate an arbitrary file. Exploitation requires an application that passes attacker-controlled arguments to these methods.(CVE-2026-67323)\n\nGitPython 3.1.50 fails to recognize joined short-option forms such as -u<value> (the short form of --upload-pack=<value>) when enforcing its default unsafe-option gate. When an application passes attacker-influenced clone options into Repo.clone_from(..., multi_options=..., allow_unsafe_options=False), an attacker can supply -u<helper> to bypass the gate that blocks --upload-pack/-u, causing Git to execute the specified helper command during clone. Fixed in 3.1.51.(CVE-2026-67324)\n\nGitPython before 3.1.51 contains an incomplete command injection blocklist that fails to account for git's long-option prefix abbreviation feature. Attackers can bypass the unsafe options guard by using abbreviated option names like upload_p instead of upload_pack, which git resolves to dangerous options and executes arbitrary commands.(CVE-2026-67325)\n\nGitPython before 3.1.50 fails to validate newline characters in the section parameter of config_writer(), allowing attackers to inject arbitrary section headers into .git/config. Attackers can inject newlines to create a forged [core] section with hooksPath pointing to attacker-controlled directories, achieving remote code execution when git hooks are triggered.(CVE-2026-67326)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP4","name":"python-GitPython","purl":"pkg:rpm/openEuler/python-GitPython&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.52-1.oe2403sp4"}]}],"ecosystem_specific":{"noarch":["python-GitPython-help-3.1.52-1.oe2403sp4.noarch.rpm","python3-GitPython-3.1.52-1.oe2403sp4.noarch.rpm"],"src":["python-GitPython-3.1.52-1.oe2403sp4.src.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3249"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67322"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67323"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67324"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67325"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67326"}],"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/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"}],"database_specific":{"severity":"Critical"}}
