CVE-2026-95624Hinoki check available

Update rollback via webview-controlled downgrade flag

Published Sep 22, 2026 · Updated Sep 22, 2026

Improper authorization in Tauri Updater Plugin 2.8.0 through 2.11.0 allows context-dependent attackers to permit signed update rollbacks. The check IPC command accepts allowDowngrades from frontend JavaScript and changes its comparator from newer-only to any different version. Exploitation requires script execution in an application's webview, such as XSS; the flaw permits selection of a genuine older signed build, while further compromise requires another bug.
