| Doc Text: |
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. 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.
