Attackers can host a repository whose default branch is named --pathspec-from-file=<path>, causing cloning applications that check out the active branch to leak file contents through GitCommandError messages.","categories":["Unclassified"],"product":"GitPython","vendor":"gitpython-developers","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110859","source_modified_at":"2026-10-15T15:40:26.986Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"GitPython","vendor":"gitpython-developers","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"3.2.0"},{"version":"3.2.0","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110859","source_modified_at":"2026-10-15T15:40:26.986Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"GitPython","ecosystem":null},"version":"3.2.0","basis":"first unaffected version stated in the CVE record"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0031,"percentile":0.2263,"score_date":"2026-10-23"},"published_at":"2026-10-14T22:52:43.585Z","modified_at":"2026-10-15T15:40:26.986Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-110859","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:40:26.986Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-110859","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-23mf-xhv8-69c2","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/gitpython-before-3.2.0-arbitrary-file-read-via-head-checkout-branch-name","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-15T15:39:51.208253Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:40:26.986Z","content_hash":"1591cf6962f67932d810a349d55bbe3c6303a64bfab51604ccd60d8d6f728798"}}
