Detection Guidance

You can detect this vulnerability by monitoring for unauthorized AJAX requests to the 'RemoveItems' action in the eyewear-prescription-form plugin. Specifically, look for HTTP POST requests to admin-ajax.php with the parameter 'action=RemoveItems' coming from unauthenticated sources. A sample command using curl to test this could be: curl -X POST 'https://yourwordpresssite.com/wp-admin/admin-ajax.php' -d 'action=RemoveItems&catIds=1'. Additionally, inspecting your web server logs or using network monitoring tools to filter for such AJAX calls without proper authentication can help detect exploitation attempts. [1]
