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 Pretty Google Calendar plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the pgcal_ajax_handler() function in all versions up to, and including, 2.0.0. This makes it possible for unauthenticated attackers to retrieve the Google API key set in the plugin's 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 Pretty Google Calendar WordPress plugin has a broken access control vulnerability where the pgcal_ajax_handler() function lacks a capability check. This allows any unauthenticated user to make AJAX requests and retrieve the Google API key configured in plugin settings, exposing sensitive credentials.

MitigationUpdate to version 2.0.1 or later which includes the missing capability check. If no update is available, consider disabling the plugin, restricting the ajax endpoint via .htaccess or web server rules, and rotate the exposed API key as a precautionary measure.

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 plugin is installed
    Navigate to WordPress admin > Plugins and look for 'Pretty Google Calendar' or check the plugins directory for the pgcal folder
    Affected if The plugin is installed and active
  2. Check installed version
    In WordPress admin > Plugins, find Pretty Google Calendar and read the version number displayed below the plugin name. Alternatively, open wp-content/plugins/pretty-google-calendar/readme.txt and check the version in the header
    Affected if Version is below 2.0.1 (the fixed version)
  3. Test unauthenticated AJAX access
    Send a POST request to wp-admin/admin-ajax.php with action=pgcal_ajax_handler and observe the response. Example: curl -X POST https://yoursite.com/wp-admin/admin-ajax.php -d 'action=pgcal_ajax_handler'
    Affected if The request returns a successful response without requiring authentication or a nonce token
  4. Verify API key exposure
    Examine the response from the AJAX request in step 3. Look for the Google API key in the returned data (typically in a field named 'api_key', 'key', or within plugin settings response)
    Affected if The response contains a Google API key or other sensitive credential that should not be accessible to unauthenticated users

If the plugin is installed, version is below 2.0.1, and the AJAX endpoint responds to unauthenticated requests with API credentials, the environment is affected by CVE-2025-12898.
