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.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-5fqc-mrg8-w798","tags":[]},{"url":"https://www.vulncheck.com/advisories/dulwich-0.23.1-before-1.2.8-symlink-path-traversal-via-filter-branch-index-filter","tags":[]}],"exploitRefs":[{"url":"https://github.com/jelmer/dulwich/security/advisories/GHSA-5fqc-mrg8-w798","tags":[]}],"hasPoc":true,"ai":null}
