## How to fix

## Technical details

The plugin fails to sanitize input and properly escape output on the 'content' parameter, allowing authenticated subscribers to inject JavaScript. The vulnerability is exposed through the color_scheme field on user profiles when registered via Redux_Users::set_profile(), which renders an unprotected nonce on /wp-admin/profile.php accessible to all logged-in users. Exploitation results in stored XSS that executes in the context of any user visiting the compromised page.
