How to fix?

Upgrade backpack/crud to version 6.8.14, 7.0.38 or higher.

Overview

backpack/crud is a package that helps you build an admin interface for your Eloquent models, using Laravel 5

Affected versions of this package are vulnerable to Arbitrary File Upload via the HasUploadFields process. An attacker can execute arbitrary code on the server by uploading a file with a server-executable extension through an upload-enabled panel. This is only exploitable if the attacker has authenticated administrator access, the upload field lacks MIME type validation, the public disk is used, php artisan storage:link is in place, and the web server is configured with PHP-FPM.
