CVE-2026-74933: 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.

Event History
Frequently Asked Questions
Which deployments are exposed?
WordPress sites using GenieWords versions 1.5.27 through 1.5.34 are affected. The issue is reachable through the plugin's REST API and AJAX actions and does not require authentication.
What does an attacker need to exploit this?
An attacker does not need a WordPress account or privileges. Successful stored XSS execution still requires someone to load a front-end page where the injected script is rendered.
What is the practical impact of exploitation?
An unauthenticated attacker can overwrite GenieWords configuration and store arbitrary script content. The script executes on every front-end page, potentially affecting any visitor to those pages.
How can I determine whether a site may already be affected?
Review the installed GenieWords version and inspect its configuration for unexpected or script-like values. Also examine front-end page output for unrecognized injected JavaScript, since stored values are decoded before being printed.
