GenieWords 1.5.27 - 1.5.34 - Unauthenticated Stored XSS and Configuration Overwrite

The GenieWords WordPress plugin from 1.5.27 to 1.5.34 does not have authorisation checks on some of its REST API and AJAX actions, and decodes stored values before printing them, allowing unauthenticated users to overwrite its configuration and inject arbitrary web scripts that execute on every front-end page.
