{"id":"DEBIAN-CVE-2026-114098","details":"Dulwich from 0.22.5 before 1.2.8 contains a path traversal vulnerability in stash.py pop() that allows attackers to write arbitrary files outside the worktree through intermediate directory symlinks. Attackers can craft a malicious repository whose popped stash writes a payload into .git/hooks/post-checkout, achieving code execution on the next checkout.","modified":"2026-10-23T18:05:16.748703469Z","published":"2026-10-21T01:17:35.263Z","upstream":["CVE-2026-114098"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-114098"}],"affected":[{"package":{"name":"dulwich","ecosystem":"Debian:12","purl":"pkg:deb/debian/dulwich?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.21.2-1","0.21.5-1","0.21.6-1","0.22.5-1","0.22.7-1","0.22.7-2","0.24.10-1","0.24.2-1","0.24.2-2","1.0.0-1","1.0.0-2","1.1.0-1","1.1.0-2","1.1.0-3","1.2.0-1","1.2.1-1","1.2.11-1","1.2.12-1","1.2.17-1","1.2.5-1","1.2.7-1","1.2.7-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114098.json"}},{"package":{"name":"dulwich","ecosystem":"Debian:13","purl":"pkg:deb/debian/dulwich?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.22.7-1","0.22.7-2","0.24.10-1","0.24.2-1","0.24.2-2","1.0.0-1","1.0.0-2","1.1.0-1","1.1.0-2","1.1.0-3","1.2.0-1","1.2.1-1","1.2.11-1","1.2.12-1","1.2.17-1","1.2.5-1","1.2.7-1","1.2.7-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114098.json"}},{"package":{"name":"dulwich","ecosystem":"Debian:14","purl":"pkg:deb/debian/dulwich?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.8-1"}]}],"versions":["0.22.7-1","0.22.7-2","0.24.10-1","0.24.2-1","0.24.2-2","1.0.0-1","1.0.0-2","1.1.0-1","1.1.0-2","1.1.0-3","1.2.0-1","1.2.1-1","1.2.5-1","1.2.7-1","1.2.7-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114098.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
