{"cve":"CVE-2026-24686","nvd":{"published":"2026-01-27T01:16:02.790","modified":"2026-06-17T10:23:25.357","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N","score":4.7},"cwes":["CWE-22"],"references":["https://github.com/theupdateframework/go-tuf/commit/d361e2ea24e427581343dee5c7a32b485d79fcc0","https://github.com/theupdateframework/go-tuf/security/advisories/GHSA-jqc5-w2xx-5vq4"],"products":["theupdateframework:go-tuf"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-24686","score":0.00231,"percentile":0.14046,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-jqc5-w2xx-5vq4","url":"https://osv.dev/vulnerability/GHSA-jqc5-w2xx-5vq4","summary":"go-tuf Path Traversal in TAP 4 Multirepo Client Allows Arbitrary File Write via Malicious Repository Names","modified":"2026-09-10T03:50:33.249256620Z","packages":[{"ecosystem":"Go","name":"github.com/theupdateframework/go-tuf/v2","purl":"pkg:golang/github.com/theupdateframework/go-tuf/v2","ranges":["<2.4.1"],"fixed":["2.4.1"]}]},{"id":"GO-2026-4377","url":"https://osv.dev/vulnerability/GO-2026-4377","summary":"Path traversal in TAP 4 multirepo client allows arbitrary file write via repo names in github.com/theupdateframework/go-tuf","modified":"2026-02-26T18:26:44Z","packages":[{"ecosystem":"Go","name":"github.com/theupdateframework/go-tuf/v2","purl":"pkg:golang/github.com/theupdateframework/go-tuf/v2","ranges":["<2.4.1"],"fixed":["2.4.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
