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 checksWork through these to decide whether this CVE applies to you.
-
Locate the plugin installationAccess 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 nameAffected if The plugin folder exists in the plugins directory
-
Identify the installed versionOpen 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 PluginsAffected if The version listed is 4.0.2 or lower
-
Inspect plugin for missing capability checksReview 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 logicAffected if Sensitive functions lack capability checks and can be invoked by unauthenticated users
-
Test for unauthenticated endpoint accessIf 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 consoleAffected 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate 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.
