It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-67326 exists.\n\nAffected packages and fixed versions:\n- gitpython (PyPI): affected all versions; fixed in 3.1.50\n- gitpython (PyPI): affected all versions; fixed in 3.1.50\n- GitPython (PyPI): affected all versions; fixed in 3.1.50\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-2026-67326/ (Markdown: https://insights.sbomify.com/CVE-2026-67326/index.md)","id":"CVE-2026-67326","markdown":"https://insights.sbomify.com/CVE-2026-67326/index.md","name":"CVE-2026-67326","record":{"aliases":["DEBIAN-CVE-2026-67326","ECHO-4413-137a-6247","ECHO-a193-9c05-86ff","GHSA-gmvg-8p66-77hg","GHSA-mv93-w799-cj2w","MINI-8gf4-6x7r-98x8","MINI-9c5c-c2c2-5jr4","MINI-r3v2-qxqq-9hh9","PYSEC-2026-3980","ROOT-APP-PYPI-GHSA-mv93-w799-cj2w","UBUNTU-CVE-2026-67326"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GitPython library","requires_auth":"none","summary":"Attackers can inject newlines into GitPython config sections to forge hooksPath, enabling remote code execution when git hooks trigger.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"gitpython","vendor":"gitpython_project"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"GitPython 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.
