{"id":"CVE-2026-24686","summary":"go-tuf Path Traversal in TAP 4 Multirepo Client Allows Arbitrary File Write via Malicious Repository Names","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.","aliases":["GHSA-jqc5-w2xx-5vq4","GO-2026-4377"],"modified":"2026-04-02T13:13:47.103327Z","published":"2026-01-27T00:45:43.422Z","related":["CGA-hj3w-qhv4-jjc2","SUSE-SU-2026:0403-1","SUSE-SU-2026:0757-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24686.json","cwe_ids":["CWE-22"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24686.json"},{"type":"ADVISORY","url":"https://github.com/theupdateframework/go-tuf/security/advisories/GHSA-jqc5-w2xx-5vq4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24686"},{"type":"FIX","url":"https://github.com/theupdateframework/go-tuf/commit/d361e2ea24e427581343dee5c7a32b485d79fcc0"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/theupdateframework/go-tuf","events":[{"introduced":"ecec5d3a09cfa74482f0797fa38b65a2942a655c"},{"fixed":"d361e2ea24e427581343dee5c7a32b485d79fcc0"}]}],"versions":["v2.0.0","v2.0.1","v2.0.2","v2.1.0","v2.1.1","v2.2.0","v2.3.0","v2.3.1","v2.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-24686.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
