CVE-2026-95625
Tauri framework v2 missing updater signature version number validation can be exploited into forced downgrade
CVSS Score
5.9
EPSS Score
0.2%
EPSS Percentile
13th
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.
