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.","state":0,"publishedAt":"2026-10-21T00:37:00.461+00:00","modifiedAt":"2026-10-22T15:51:35.497+00:00","affected":[{"ecosystem":"Vendor product","name":"dulwich","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"jelmer\",\n                    \"product\": \"dulwich\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:pypi/dulwich\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.23.1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.2.8\"\n                        },\n                        {\n                            \"version\": \"1.2.8\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.3,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://github.com/jelmer/dulwich/security/advisories/GHSA-5fqc-mrg8-w798","https://www.vulncheck.com/advisories/dulwich-0.23.1-before-1.2.8-symlink-path-traversal-via-filter-branch-index-filter"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-114097","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114097","identifiers":["CVE-2026-114097"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
