4th percentile - higher than 4% of all known CVEs

Summary

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.

Risk Assessment

An attacker can roll back the application to an older, potentially vulnerable version, potentially leading to exploitation of known vulnerabilities and system compromise.

Recommendation

Update the Tauri updater plugin to a version that signs and authenticates the update manifest, and consider adding additional integrity checks.
