GHSA-f8x6-m9f5-ffp8
Unrestricted Upload of File with Dangerous Type in unisharp/laravel-filemanager
Quick fix
GHSA-f8x6-m9f5-ffp8 — unisharp/laravel-filemanager: upgrade to the fixed version with the command below.
composer require unisharp/laravel-filemanager:^2.6.2Details
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).
