CVE-2026-24686: Theupdateframework Go-Tuf

Medium severity, CVSS 4.7. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Theupdateframework Go-Tuf: from 2.0.0, before 2.4.1 (fixed in 2.4.1)
