Summary: Unrestricted Upload of File with Dangerous Type in unisharp/laravel-filemanager

Details: This affects the package unisharp/laravel-filemanager prior to version 2.6.2. The `upload()` function does not sufficiently validate the file type when uploading. An attacker may be able to reproduce the following steps: - Install a package with a web Laravel application. - Navigate to the Upload window - Upload an image file, then capture the request - Edit the request contents with a malicious file (webshell) - Enter the path of file uploaded on URL - Remote Code Execution **Note: Prevention for bad extensions can be done by using a whitelist in the config file(lfm.php). Corresponding document can be found in the [here](https://unisharp.github.io/laravel-filemanager/configfolder-categories).
