Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76221 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitpython (PyPI): affected all versions; fixed in 3.1.58\n- gitpython (PyPI): affected all versions; fixed in 3.1.58\n- GitPython (PyPI): affected all versions; fixed in 3.1.58\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-76221/ (Markdown: https://insights.sbomify.com/CVE-2026-76221/index.md)","id":"CVE-2026-76221","markdown":"https://insights.sbomify.com/CVE-2026-76221/index.md","name":"CVE-2026-76221","record":{"aliases":["CLSA-2026-1787219647","DEBIAN-CVE-2026-76221","ECHO-2c16-7ddc-9a15","ECHO-9a71-300c-8276","GHSA-78pq-g4m8-fx2c","GHSA-jm78-9fvv-mhgr","MINI-3r35-53c2-g83j","MINI-7qxj-wvgx-pmj3","MINI-gvw5-8x4p-f5jh","MINI-jw86-x58w-rgg5","MINI-w8jq-jw56-hp9p","PYSEC-2026-3783","ROOT-APP-PYPI-GHSA-jm78-9fvv-mhgr","UBUNTU-CVE-2026-76221"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"GitPython library","requires_auth":"low_privilege","summary":"Attackers can inject malicious git-config directives to execute arbitrary commands via core.sshCommand or core.hooksPath in GitPython.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"gitpython","vendor":"gitpython_project"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"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","version":"4.0"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"GitPython before 3.1.58 contains a config-name injection vulnerability in the option-name validator that allows attackers to forge arbitrary git-config directives by injecting equals signs, hash symbols, and whitespace into option names.
