{"id":"DEBIAN-CVE-2026-24686","details":"go-tuf is a Go implementation of The Update Framework (TUF). go-tuf's TAP 4 Multirepo Client uses the map file repository name string (`repoName`) as a filesystem path component when selecting the local metadata cache directory. Starting in version 2.0.0 and prior to version 2.4.1, if an application accepts a map file from an untrusted source, an attacker can supply a `repoName` containing traversal (e.g., `../escaped-repo`) and cause go-tuf to create directories and write the root metadata file outside the intended `LocalMetadataDir` cache base, within the running process's filesystem permissions. Version 2.4.1 contains a patch.","modified":"2026-01-27T11:01:32.471712Z","published":"2026-01-27T01:16:02.790Z","upstream":["CVE-2026-24686"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-24686"}],"affected":[{"package":{"name":"golang-github-theupdateframework-go-tuf","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-github-theupdateframework-go-tuf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.2+0.7.0-1","2.3.0+0.7.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-24686.json"}},{"package":{"name":"golang-github-theupdateframework-go-tuf","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-github-theupdateframework-go-tuf?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.2+0.7.0-1","2.3.0+0.7.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-24686.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
