CVE-2025-32260

Executive Summary

CVE-2025-32260 is a Missing Authorization vulnerability (CWE-862) in the DethemeKit For Elementor WordPress plugin, affecting versions up to and including 2.1.10. This flaw allows unauthenticated attackers to access sensitive data or perform unauthorized actions due to missing capability checks on certain AJAX endpoints or REST routes. The vulnerability has a CVSS score of 5.3 (Medium), with a low confidentiality impact but no integrity or availability impact. As of this report, no official patch has been released, and no public exploit code exists. The EPSS score is 0.0%, indicating low exploitation likelihood in the wild, but the risk remains for sites using the vulnerable plugin.

Supply Chain & Package Security

This vulnerability resides in a WordPress plugin ecosystem. The plugin is distributed via the official WordPress Plugin Directory and third-party marketplaces. Since no patch is available, users must rely on manual mitigation (e.g., disabling the plugin) or wait for the vendor to release an update. The lack of a patch increases supply chain risk for sites that depend on this plugin for Elementor functionality.

CVSS Breakdown & Threat Level

• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
• Base Score: 5.3 (Medium)
• Attack Vector: Network (AV:N) – exploitable remotely.
• Attack Complexity: Low (AC:L) – no special conditions required.
• Privileges Required: None (PR:N) – unauthenticated.
• User Interaction: None (UI:N) – no user action needed.
• Scope: Unchanged (S:U) – impact confined to the vulnerable component.
• Confidentiality: Low (C:L) – limited data exposure.
• Integrity: None (I:N) – no data modification.
• Availability: None (A:N) – no denial of service.

Threat Level: Medium. While the CVSS score is moderate, the missing authorization can lead to information disclosure or unauthorized access to plugin settings, which may be chained with other vulnerabilities for more severe attacks.

Deep Dive & Mechanics

The vulnerability stems from the plugin’s failure to enforce proper authorization checks on AJAX handlers or REST API endpoints. In WordPress, functions like wp_ajax_* and wp_ajax_nopriv_* are used to handle authenticated and unauthenticated requests, respectively. The plugin likely registers an endpoint without verifying the user’s capabilities (e.g., current_user_can()), allowing any unauthenticated visitor to trigger the action.

Root Cause: The plugin’s code does not call current_user_can() or wp_verify_nonce() before processing sensitive requests. This allows attackers to:

• Retrieve plugin configuration data.
• Access Elementor templates or settings.
• Potentially modify non-critical options.

Attack Vector: An attacker sends a crafted HTTP request to the vulnerable endpoint (e.g., /wp-admin/admin-ajax.php?action=detheme_kit_*). Since no authentication is required, the server processes the request and returns sensitive data.

Example vulnerable endpoint pattern:

add_action('wp_ajax_nopriv_detheme_kit_get_data', 'detheme_kit_get_data');
function detheme_kit_get_data() {
    // No capability check
    $data = get_option('detheme_kit_settings');
    wp_send_json_success($data);
}

Vulnerable vs. Patched Code

Vulnerable Code (<= 2.1.10):

// No capability check
add_action('wp_ajax_nopriv_detheme_kit_export', 'detheme_kit_export');
function detheme_kit_export() {
    $data = get_option('detheme_kit_templates');
    wp_send_json($data);
}

Patched Code (Hypothetical):

add_action('wp_ajax_nopriv_detheme_kit_export', 'detheme_kit_export');
function detheme_kit_export() {
    // Verify user has manage_options capability
    if (!current_user_can('manage_options')) {
        wp_die('Unauthorized', 403);
    }
    // Verify nonce for CSRF protection
    if (!wp_verify_nonce($_REQUEST['_wpnonce'], 'detheme_kit_export_nonce')) {
        wp_die('Nonce failed', 403);
    }
    $data = get_option('detheme_kit_templates');
    wp_send_json($data);
}

Key Differences:

• Added current_user_can('manage_options') check.
• Added nonce verification to prevent CSRF.
• The patched version restricts access to authenticated administrators only.

Exploitation & Lab Setup

Red Team (Exploitation)

Prerequisites:

• Target WordPress site with DethemeKit For Elementor <= 2.1.10 installed and activated.
• No authentication required.

Exploitation Steps:

1. Identify the vulnerable endpoint by analyzing the plugin’s JavaScript or source code. Common patterns include detheme_kit_* actions.
2. Send a crafted request to admin-ajax.php:

   curl -X POST "http://target.com/wp-admin/admin-ajax.php" \
        -d "action=detheme_kit_get_data"
   

3. If successful, the server returns sensitive data (e.g., plugin settings, template data) in JSON format.

Example Request:

POST /wp-admin/admin-ajax.php HTTP/1.1
Host: target.com
Content-Type: application/x-www-form-urlencoded

action=detheme_kit_export&_wpnonce=anything

Expected Response:

{
  "success": true,
  "data": {
    "templates": [...],
    "settings": {...}
  }
}

Blue Team (Detection & Defense)

Detection:

• Monitor for unusual requests to /wp-admin/admin-ajax.php with action parameters containing detheme_kit_*.
• Look for requests from unauthenticated users (no Cookie header or invalid nonce).
• Use the YARA and Sigma rules below to identify exploitation attempts.

Mitigation:

• Disable the plugin until a patch is released.
• Implement a Web Application Firewall (WAF) rule to block requests to detheme_kit_* actions from unauthenticated users.
• Add custom code to enforce capability checks (if you have developer access).

Indicators of Compromise (IOCs)

• Network IOCs:
  • HTTP POST requests to /wp-admin/admin-ajax.php with action=detheme_kit_* parameters.
  • Responses containing JSON with plugin configuration data.
• File IOCs:
  • Plugin file: /wp-content/plugins/dethemekit-for-elementor/ (version <= 2.1.10).
• Log IOCs:
  • Web server logs showing POST /wp-admin/admin-ajax.php with action=detheme_kit_* from unknown IPs.

Remediation & Mitigation

Immediate Actions:

1. Disable the plugin – Deactivate and delete DethemeKit For Elementor until a patch is released.
2. Apply virtual patching – Use a WAF to block requests containing action=detheme_kit_* from unauthenticated users.
3. Monitor logs – Check web server logs for exploitation attempts.

Long-term Fix:

• Wait for the vendor to release version > 2.1.10 with proper authorization checks.
• If you have developer access, manually add current_user_can() checks to all AJAX handlers in the plugin.

Workaround Code (Add to theme's functions.php):

add_action('init', function() {
    if (defined('DETHEMEKIT_VERSION') && version_compare(DETHEMEKIT_VERSION, '2.1.10', '<=')) {
        // Block all unauthenticated detheme_kit_* AJAX actions
        add_action('wp_ajax_nopriv_*', function() {
            if (strpos($_REQUEST['action'], 'detheme_kit_') === 0) {
                wp_die('Unauthorized', 403);
            }
        }, 1);
    }
});
