CVE-2026-95624 · Severity: medium · CVSS 6.8 · Published 2026-09-22

The Tauri updater plugin allows frontend JavaScript code to bypass rollback protection by setting an allowDowngrades parameter to true, which disables version checks. An attacker exploiting an XSS vulnerability in a Tauri application can invoke this to downgrade the app to an older, vulnerable version without needing to fake a higher version number. This could allow installation of malicious code or restoration of patched vulnerabilities.

## Technical details

The updater's 'check' IPC command accepts an allowDowngrades boolean parameter from untrusted frontend code, which bypasses the normal "update must be newer" version comparator. Default permissions grant allow-check to the webview, so any XSS in the frontend can trigger downgrade attacks. When combined with a secondary vulnerability, this enables full rollback without version spoofing.
