Security Advisory
CVE-2026-24686
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
go-tuf is a Go implementation of The Update Framework (TUF). go-tufs 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 processs filesystem permissions. Version 2.4.1 contains a patch.
