NewCVE-2026-95624 (opens in a new tab)How to fix?
Upgrade @tauri-apps/plugin-updater to version 2.12.0 or higher.
Overview

Affected versions of this package are vulnerable to Improper Authorization via the allowDowngrades option exposed to the frontend JavaScript API, which allowed any web content running inside a Tauri application to request installation of an older, previously released version of the application. Because the updater only verifies the cryptographic signature of the downloaded artifact and not whether the version is newer than the currently running one, a malicious or compromised web page could trigger a downgrade to a version known to contain vulnerabilities. The fix removes the allowDowngrades option from the frontend API and moves control of this behaviour exclusively to the application-level configuration, where it cannot be influenced by untrusted web content.
