GHSA-f8x6-m9f5-ffp8 Unrestricted Upload of File with Dangerous Type in unisharp/laravel-filemanager

• Packagist unisharp/laravel-filemanager: < 2.6.2 → fixed in 2.6.2

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).
