CVE-2026-65433Network attack vector

Subscriber-level menu modification via unchecked AJAX authorization

Published Jul 27, 2026 · Updated Jul 27, 2026

Missing authorization in ThemeWant RT Mega Menu 1.5.1 and earlier allows remote authenticated users to modify mega-menu settings. The plugin's menu-option AJAX handlers accept configuration changes after nonce validation without checking the caller's WordPress capability. Subscriber access is sufficient, and successful requests can alter site navigation configuration without granting code execution or data disclosure.
