Attackers can craft a repository where an ancestor commit's symlink redirects a descendant commit's file writes during filter_branch, enabling code execution by writing into .git/hooks.","categories":["Libraries & packages"],"product":"dulwich","vendor":"jelmer","ecosystem":"PyPI","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114097","source_modified_at":"2026-10-22T15:51:35.497Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"dulwich","vendor":"jelmer","versions":[{"version":"0.23.1","status":"affected","versionType":"semver","lessThan":"1.2.8"},{"version":"1.2.8","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-5fqc-mrg8-w798","source_modified_at":"2026-10-21T10:57:27.569314986Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"dulwich","ecosystem":"PyPI","purl":"pkg:pypi/dulwich"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.23.1"},{"fixed":"1.2.8"}]}],"versions":["0.23.1","0.23.2","0.24.0","0.24.1","0.24.10","0.24.2","0.24.3","0.24.4","0.24.5","0.24.6","0.24.7","0.24.8","0.24.9","0.25.0","0.25.1","0.25.2","1.0.0","1.1.0","1.2.0","1.2.1","1.2.2","1.2.3","1.2.4","1.2.5","1.2.6","1.2.7"]}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114097","source_modified_at":"2026-10-22T15:51:35.497Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"dulwich","ecosystem":null},"version":"1.2.8","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-5fqc-mrg8-w798","source_modified_at":"2026-10-21T10:57:27.569314986Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"dulwich","ecosystem":"PyPI","purl":"pkg:pypi/dulwich"},"version":"1.2.8"}],"cvss":7.3,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00152,"percentile":0.04002,"score_date":"2026-10-23"},"published_at":"2026-10-21T00:37:00.461Z","modified_at":"2026-10-22T15:51:35.497Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-114097","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-22T15:51:35.497Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-5fqc-mrg8-w798","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-21T10:57:27.569314986Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-114097","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-5fqc-mrg8-w798","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/dulwich-0.23.1-before-1.2.8-symlink-path-traversal-via-filter-branch-index-filter","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-22T15:51:27.066995Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-22T15:51:35.497Z","content_hash":"6070a69eba98b08e2589f4e34198ef3c6575805332ca0af572e0cfdea2afb5b0"}}
