Missing Authorization vulnerability in Kestrel WooCommerce AWeber Newsletter Subscription.This issue affects WooCommerce AWeber Newsletter Subscription: from n/a through 4.0.2.

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 · moderate confidence

Missing Authorization vulnerability in the Kestrel WooCommerce AWeber Newsletter Subscription WordPress plugin (versions up to 4.0.2). The plugin fails to implement proper authorization checks on certain functions or endpoints, allowing unauthenticated attackers to access sensitive functionality that should require higher privileges.

MitigationUpdate to version 4.0.3 or later which contains the authorization fix. If no update available, review plugin code to identify and add capability checks or nonce validation to all admin/privileged functions.

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. Locate the plugin installation
    Access your WordPress site via FTP or file manager and navigate to wp-content/plugins/ - look for a folder named 'kestrel-aweber-newsletter' or similar containing 'aweber' and 'woocommerce' in the name
    Affected if The plugin folder exists in the plugins directory
  2. Identify the installed version
    Open the main plugin PHP file (usually named similar to the folder) and look for the plugin header comment containing 'Version:' - or check in WordPress admin under Plugins > Installed Plugins
    Affected if The version listed is 4.0.2 or lower
  3. Inspect plugin for missing capability checks
    Review the plugin PHP files for functions that handle admin or privileged operations - search for 'add_action' or 'add_shortcode' hooks and check if they include 'current_user_can' or 'capability' validation before executing sensitive logic
    Affected if Sensitive functions lack capability checks and can be invoked by unauthenticated users
  4. Test for unauthenticated endpoint access
    If the plugin exposes AJAX handlers or REST API endpoints (look for 'wp_ajax_' or 'register_rest_route'), attempt to call them without authentication using a tool like curl or browser developer console
    Affected if The endpoint responds successfully without requiring login credentials

Your environment is affected if the Kestrel AWeber Newsletter plugin is installed at version 4.0.2 or lower and sensitive functions or endpoints lack authorization validation.
