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 MDJM Event Management plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check on the 'custom_fields_controller' function in all versions up to, and including, 1.7.8.1. This makes it possible for unauthenticated attackers to delete arbitrary custom event fields via the 'delete_custom_field' and 'id' parameters.

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 MDJM Event Management WordPress plugin lacks authorization checks on the custom_fields_controller function, allowing unauthenticated attackers to delete arbitrary custom event fields by manipulating the delete_custom_field and id parameters. This is a Broken Access Control (CWE-862) vulnerability with CVSS 5.3.

MitigationUpdate the plugin to the latest version to receive the patched code that adds capability checks to the custom_fields_controller function, or manually add WordPress capability verification (current_user_can) before allowing field deletion operations.

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. Confirm MDJM Event Management plugin is installed
    In WordPress admin, navigate to Plugins > Installed Plugins and look for 'MDJM Event Management' in the list. Alternatively, check the /wp-content/plugins/ directory for the mdjm-event-management folder.
    Affected if The plugin is installed and active
  2. Identify the installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins and click on 'View details' for MDJM Event Management to see the version number. Alternatively, check the main plugin PHP file for the Version header in the plugin comment block.
    Affected if The installed version is within any affected version range (compare against release notes or security advisories)
  3. Verify custom event fields functionality is in use
    Check if custom event fields have been created in the plugin settings: Navigate to MDJM > Settings > Custom Fields (or similar path depending on plugin version). Look for any custom field definitions listed.
    Affected if Custom event fields exist in the configuration
  4. Inspect the custom_fields_controller function for authorization checks
    Locate the plugin file containing custom_fields_controller (typically in includes/ or admin/ directories). Examine the function to verify it includes capability checks such as current_user_can or similar authorization logic before processing delete_custom_field parameter operations.
    Affected if The function lacks WordPress capability verification (current_user_can) before allowing field deletion operations

You are affected if the MDJM Event Management plugin is installed, custom event fields are configured, and the custom_fields_controller function does not verify user capabilities before processing field deletion requests.

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

Update the plugin to the latest version to receive the patched code that adds capability checks to the custom_fields_controller function, or manually add WordPress capability verification (current_user_can) before allowing field deletion operations.

Recommended fix Moderate confidence

MDJM Event Management plugin version 1.7.9 or higher

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Locate the 'MDJM Event Management' plugin
  4. Check if the current version is 1.7.8.1 or below
  5. If vulnerable, click 'Update now' to install the latest version (1.7.9 or higher)
  6. Verify the update was successful and the plugin is now at version 1.7.9 or later
