Description

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.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v ≥ 2.12.02.0.0 ≤ v < 2.12.02.0.02.12.0
Affected range stops below 2.12.0, so it looks safe — our inference, not a vendor statement
