CVE-2026-95625
Tauri framework v2 missing updater signature version number validation can be exploited into forced downgrade
- Published
- Updated
- Reserved
- Assigned by
- JFROG
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.

What to do
Solution: addressed in tauri-plugin-updater 2.12.0, and it has to be switched on. The new requireSignedVersion option compares the version announced by the endpoint against the version recorded in the signature's trusted comment, which the signature does cover, and rejects the update when they differ.
