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.
