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 WP Go Maps (formerly WP Google Maps) plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the processBackgroundAction() function in all versions up to, and including, 10.0.04. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify global map engine settings.

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 WP Go Maps WordPress plugin lacks a capability check on the processBackgroundAction() function, allowing any authenticated user with Subscriber-level access or higher to modify global map engine settings. This is a broken access control vulnerability where the function processes background actions without verifying the user has appropriate administrative privileges.

MitigationUpdate the plugin to version 10.0.05 or later once available. Until then, implement a capability check (e.g., current_user_can('manage_options')) at the beginning of the processBackgroundAction() function to restrict access to administrators only.

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 WP Go Maps plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and locate 'WP Go Maps' (or 'GoMap'/'WP Google Maps' - the plugin was formerly known by these names). Note the installed version number.
    Affected if Plugin is installed and version is unknown or below 10.0.05
  2. Confirm installed version against fixed release
    Compare the noted version to 10.0.05. Check the plugin's changelog or repository for version history if available.
    Affected if Version is below 10.0.05 or cannot be determined (plugin may be unmaintained)
  3. Locate the processBackgroundAction function
    Access the plugin files via WP admin > Plugins > Plugin Editor or via file system (wp-content/plugins/wp-go-maps/). Search for 'processBackgroundAction' in PHP files.
    Affected if Function exists in the plugin code without a capability check at the beginning
  4. Check for capability verification in the function
    Examine the first 5-10 lines of the processBackgroundAction function. Look for current_user_can() or similar WordPress capability checks.
    Affected if No capability check (such as current_user_can('manage_options')) is present at the start of the function
  5. Identify subscriber or higher-level user accounts
    In WordPress admin, go to Users > All Users. Review the role column for any users with Subscriber, Contributor, Author, or Editor roles.
    Affected if Any authenticated user account with Subscriber role or higher exists in the system

If the plugin is installed, version is below 10.0.05, and the processBackgroundAction function exists without a capability check, the site is affected provided any subscriber-level or higher user account exists.

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

Update the plugin to version 10.0.05 or later once available. Until then, implement a capability check (e.g., current_user_can('manage_options')) at the beginning of the processBackgroundAction() function to restrict access to administrators only.

Recommended fix Moderate confidence

Update to the latest version of WP Go Maps (after version 10.0.04) which should contain the capability check fix for the processBackgroundAction() function

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Locate WP Go Maps (formerly WP Google Maps) in the plugin list
  4. Click 'Update now' if an update is available, or manually upload the latest version from the WordPress plugin repository
  5. After updating, verify that the map functionality still works correctly
Caveat Review plugin settings after upgrade as configuration changes may have occurred during the update process
