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 CE21 Suite plugin for WordPress is vulnerable to unauthorized plugin settings update due to a missing capability check on the wp_ajax_nopriv_ce21_single_sign_on_save_api_settings AJAX action in versions 2.2.1 to 2.3.1. This makes it possible for unauthenticated attackers to update the plugin's API settings including a secret key used for authentication. This allows unauthenticated attackers to create new admin accounts on an affected site.

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 CE21 Suite plugin registers an AJAX action 'ce21_single_sign_on_save_api_settings' with wp_ajax_nopriv_ hook, making it accessible to unauthenticated users. The handler lacks a capability check (e.g., current_user_can('manage_options')), allowing any visitor to modify API settings including secret keys and create new WordPress admin accounts.

MitigationUpdate to version 2.3.2 or later which adds proper capability verification. Until patched, consider disabling the plugin or using WAF rules to block the affected AJAX endpoint.

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. Check CE21 Suite plugin version
    Log into WordPress admin, go to Plugins > Installed Plugins, locate CE21 Suite, and note the version number displayed. Alternatively, open wp-content/plugins/ce21-suite/ce21-suite.php and look for the 'Version:' header comment.
    Affected if The installed version is lower than 2.3.2 (the version that patched this vulnerability).
  2. Identify the vulnerable AJAX endpoint
    Locate the plugin PHP file that registers the AJAX action. Search for 'ce21_single_sign_on_save_api_settings' and verify it is registered with 'wp_ajax_nopriv_' prefix, which makes it accessible to unauthenticated users.
    Affected if The AJAX action is registered with wp_ajax_nopriv_ce21_single_sign_on_save_api_settings, meaning it can be accessed by any visitor without authentication.
  3. Verify capability check is missing
    Find the handler function for the AJAX action (the callback that processes the request). Search within that function for a capability check like current_user_can('manage_options') or similar authorization logic.
    Affected if The handler function lacks any capability check or authorization validation, allowing anyone to execute it.
  4. Confirm the endpoint is reachable
    Send a POST request to your WordPress site at /wp-admin/admin-ajax.php with the action parameter set to 'ce21_single_sign_on_save_api_settings'. A valid response (rather than a 403 or authentication error) confirms the endpoint is accessible to unauthenticated users.
    Affected if The AJAX endpoint responds to unauthenticated requests without redirecting to a login page or returning a capability error.

A user is affected if the CE21 Suite plugin version is below 2.3.2 AND the AJAX endpoint 'ce21_single_sign_on_save_api_settings' is accessible without authentication and lacks capability verification.

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

Update to version 2.3.2 or later which adds proper capability verification. Until patched, consider disabling the plugin or using WAF rules to block the affected AJAX endpoint.

Recommended fix Moderate confidence

Version 2.3.2 or later

  1. Log in to WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Find the CE21 Suite plugin in the list
  4. Check if an update to version 2.3.2 or later is available
  5. If update available, click 'Update Now' to install the fixed version
  6. If no automatic update is available, manually download the latest version from wordpress.org and upload via Plugins > Add New > Upload Plugin
  7. After updating, verify the plugin is running version 2.3.2 or later
