Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Ziggeo plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.1.1. The wp_ajax_ziggeo_ajax handler only verifies a nonce (check_ajax_referer) but performs no capability checks via current_user_can(). Furthermore, the nonce ('ziggeo_ajax_nonce') is exposed to all logged-in users on every page via the wp_head and admin_head hooks . This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke multiple administrative operations including: saving arbitrary translation strings (translations_panel_save_strings via update_option('ziggeo_translations')), creating/updating/deleting event templates (event_editor_save_template/update_template/remove_template via update_option('ziggeo_events')), modifying SDK application settings (sdk_applications operations), and managing notifications (notification_handler via update_option('ziggeo_notifications')).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Ziggeo WordPress plugin has a Missing Authorization vulnerability where the wp_ajax_ziggeo_ajax handler only verifies a nonce but performs no capability checks via current_user_can(). The nonce is exposed to all logged-in users via wp_head/admin_head hooks, allowing authenticated attackers with Subscriber-level access and above to perform administrative operations including saving translation strings, managing event templates, modifying SDK settings, and managing notifications.

MitigationAdd capability checks (current_user_can) to all AJAX handlers to ensure only users with appropriate permissions (e.g., manage_options) can perform administrative operations. Additionally, fix the nonce exposure by not printing it globally or by using admin-only hooks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Ziggeo plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Ziggeo' or check wp-content/plugins directory for ziggeo-video folder. Note the installed version from the plugin headers.
    Affected if Ziggeo plugin is installed and no version fix has been applied
  2. Verify AJAX handler exists
    Check the plugin source files (typically in ziggeo-video.php or includes/ajax.php) for the 'wp_ajax_ziggeo_ajax' action hook. Search for 'add_action("wp_ajax_ziggeo_ajax"' or similar patterns.
    Affected if The wp_ajax_ziggeo_ajax AJAX handler is present in the plugin
  3. Confirm nonce exposure to low-privilege users
    Inspect plugin code for nonce generation within head hooks (wp_head or admin_head). Look for wp_create_nonce() calls that pass the 'ziggeo_ajax' action and are output in areas accessible to all logged-in users, including Subscribers.
    Affected if The nonce is output in public-facing or user-specific head hooks accessible to Subscriber-level users
  4. Check for missing capability checks
    Review the AJAX handler callback function (the function handling wp_ajax_ziggeo_ajax). Look for 'current_user_can(' calls before performing administrative actions like update_option(), modifying translations, event templates, or SDK settings.
    Affected if The AJAX handler performs update_option() or similar administrative calls without first verifying current_user_can('manage_options') or equivalent
  5. Identify vulnerable update_option calls
    Search the AJAX handler code for update_option() calls related to ziggeo_translations, ziggeo_events, ziggeo_app_options, or notification settings. Verify these can be reached without permission checks.
    Affected if Administrative options (translations, event templates, SDK settings, notifications) can be modified via update_option() without capability verification

The environment is affected if the Ziggeo WordPress plugin is installed and its AJAX handler allows any authenticated Subscriber-level user to modify administrative settings without capability verification.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Add capability checks (current_user_can) to all AJAX handlers to ensure only users with appropriate permissions (e.g., manage_options) can perform administrative operations. Additionally, fix the nonce exposure by not printing it globally or by using admin-only hooks.

Recommended fix Moderate confidence

Version 3.1.2 or later (check wordpress.org for the latest stable release)

  1. 1. Navigate to the WordPress admin dashboard
  2. 2. Go to Plugins > Installed Plugins
  3. 3. Locate the Ziggeo plugin
  4. 4. If an update is available, click 'Update Now' to install the latest version
  5. 5. If no update is available in the WordPress admin, visit the Ziggeo plugin page on wordpress.org to download the latest version
  6. 6. Deactivate the current Ziggeo plugin
  7. 7. Upload and install the latest version of the Ziggeo plugin
  8. 8. Reactivate the Ziggeo plugin
Caveat Review plugin settings after upgrade as some configuration changes may have occurred
