An attacker can exploit it over the internet without logging in, 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-2026-110855 exists.\n\nAffected packages and fixed versions:\n- GitPython (PyPI): affected all versions; fixed in 3.2.0\n- gitpython (PyPI): affected all versions; fixed in 3.2.0\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-2026-110855/ (Markdown: https://insights.sbomify.com/CVE-2026-110855/index.md)","id":"CVE-2026-110855","markdown":"https://insights.sbomify.com/CVE-2026-110855/index.md","name":"CVE-2026-110855","record":{"aliases":["DEBIAN-CVE-2026-110855","ECHO-ccb0-88c2-6cda","GHSA-cwpg-5qqf-hf36","GHSA-fx3j-rwgx-fr94","MINI-3xmf-8hf8-xwmf","UBUNTU-CVE-2026-110855"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"GitPython library","requires_auth":"none","summary":"Attackers can expose environment variables by crafting malicious .gitmodules files, leaking secrets in directory names and logs.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"GitPython before 3.2.0 contains an information disclosure vulnerability that allows malicious repositories to expand environment variables via separate_git_dir in Repo._clone(), which omits expand_vars=False when calling Git.polish_url().
