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 Cliengo – Chatbot plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'update_session' function in all versions up to, and including, 3.0.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the session token of the chatbot.

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 Cliengo WordPress plugin contains a broken access control vulnerability where the 'update_session' function lacks proper capability verification. This allows any authenticated user with Subscriber-level permissions or higher to modify chatbot session tokens without authorization, enabling unauthorized modification of application data.

MitigationUpdate the plugin to version 3.0.3 or later which implements proper capability checks on the update_session function to ensure only authorized users can modify session data.

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 Cliengo plugin is installed
    Navigate to WordPress admin > Plugins and look for 'Cliengo' in the list of installed plugins. Note whether it is active or inactive.
    Affected if The Cliengo plugin is installed and active
  2. Identify the installed plugin version
    In the Plugins list, find the Cliengo plugin and check the version number displayed below the plugin name. Compare this to the fixed version 3.0.3.
    Affected if The installed version is lower than 3.0.3
  3. Verify user roles with Subscriber access exist
    Go to WordPress admin > Users and review the list of user accounts. Check if any users have the 'Subscriber' role assigned.
    Affected if There is at least one user with Subscriber-level permissions
  4. Check if AJAX endpoints are accessible
    Inspect the plugin files (typically in wp-content/plugins/cliengo) for the update_session function and verify the AJAX action is registered without capability checks. Look for add_action('wp_ajax_update_session', ...) or similar without a capability check like current_user_can() before execution.
    Affected if The update_session function is accessible without proper capability verification (versions below 3.0.3)
  5. Test endpoint access with low-privilege account
    If you have a test environment, attempt to access the update_session AJAX endpoint using a user with only Subscriber permissions to confirm unauthorized access is possible.
    Affected if A Subscriber-level user can successfully modify chatbot session tokens

You are affected if the Cliengo plugin is installed with a version lower than 3.0.3 and your site has any users with Subscriber-level permissions or higher.
