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.

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. Verify Ultimate Post Kit plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Ultimate Post Kit' by bdthemes, or check the /wp-content/plugins/ directory for the ultimate-post-kit folder
    Affected if Plugin is installed and active
  2. Check installed plugin version
    In WordPress admin plugins list, view the version column for Ultimate Post Kit, or read version from plugin's main PHP file header in /wp-content/plugins/ultimate-post-kit/
    Affected if Version is any release prior to the patched version (update to latest available version recommended)
  3. Inspect publicly accessible AJAX endpoints
    Check plugin source code for wp_ajax and wp_ajax_nopriv hooks - look in main plugin file for add_action('wp_ajax_...') and add_action('wp_ajax_nopriv_...') calls that may expose privileged actions
    Affected if Plugin registers actions with wp_ajax_nopriv hook allowing unauthenticated access to functionality meant for authenticated users
  4. Test for unauthorized access to admin functions
    Make unauthenticated HTTP requests to common plugin AJAX actions (such as ?action=ultimate_post_kit_... or /wp-json/ultimate-post-kit/... endpoints) and verify if they return expected data without requiring login
    Affected if Requests return successful responses or privileged data without authentication tokens or cookies
  5. Review plugin access control settings
    In WordPress admin, navigate to Ultimate Post Kit settings pages and check any options related to user roles, permissions, or access control levels for misconfiguration
    Affected if Settings allow 'guest' or unauthenticated users to access premium or restricted features

If Ultimate Post Kit is installed and exposes any AJAX actions or API endpoints to unauthenticated users without proper permission checks, the environment is affected by this authorization bypass.
