Summary

The Simple Cloudflare Turnstile plugin for WordPress has a vulnerability that allows authenticated users with contributor-level and above permissions to exploit stored cross-site scripting. This occurs through the 'gravity-simple-turnstile' shortcode, where insufficient input sanitization and output escaping for user-supplied attributes permit the injection of arbitrary web scripts into pages. When these altered pages are accessed by other users, the injected scripts are triggered, potentially leading to unauthorized actions and data exposure.

Affected Version(s)

Simple Cloudflare Turnstile – CAPTCHA Alternative * <= 1.23.1
