An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-87817 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitpython (PyPI): affected all versions; fixed in 3.1.60\n- gitpython (PyPI): affected all versions; fixed in 3.1.60\n- gitpython (PyPI): affected all versions; fixed in 3.1.60\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-2026-87817/ (Markdown: https://insights.sbomify.com/CVE-2026-87817/index.md)","id":"CVE-2026-87817","markdown":"https://insights.sbomify.com/CVE-2026-87817/index.md","name":"CVE-2026-87817","record":{"aliases":["DEBIAN-CVE-2026-87817","ECHO-da18-07c8-f77a","GHSA-239g-whfq-7xj9","MINI-36cp-prvh-9228","MINI-78gr-h522-rmv9","MINI-fvj2-g7hw-46q6","MINI-wjwx-3r6h-8f68","PYSEC-2026-3982","UBUNTU-CVE-2026-87817"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"GitPython library","requires_auth":"none","summary":"Attackers can execute arbitrary code by impersonating the git directory and placing malicious hooks, affecting users of the GitPython library.","user_interaction":"required","vuln_class":"code_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:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"GitPython before 3.1.60 fails to properly validate the git directory location, allowing attackers to impersonate the git directory using tracked files like gitdir, commondir, and HEAD.
