CVE-2026-24686
January 27, 2026
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.
