CVE-2026-23991 is a medium severity vulnerability in go-tuf, a Go implementation of The Update Framework (TUF). Versions from 2.0.0 up to but not including 2.3.1 are affected. The vulnerability arises when the TUF repository or its mirrors return invalid but syntactically correct JSON metadata that is not well-formed according to TUF specifications. This causes the client to panic during parsing before signature validation, resulting in a denial of service (DoS). An attacker controlling a repository, mirror, or cache can exploit this without needing signing keys. No user interaction or authentication is required, and no known workarounds exist.
