Original description

The description as published by the source.

The Tauri updater plugin verifies update binaries using minisign signatures, but the signature covers only the raw binary bytes. The update manifest -- which contains the version number, download URL, and signature -- is fetched over TLS but is never itself signed or authenticated. Because the only anti-rollback check compares the manifest's version field against the current version, and that field is unsigned, an attacker who can serve a crafted manifest can force installation of any older signed release without possessing the developer's private key.
