    "summary": "xShop is an open-source shop developed in Laravel. An Unrestricted File Upload vulnerability in xShop version 3.0.3 allows an authenticated administrator to upload executable files (e.g., .php). By uploading a specially crafted php file, an attacker can achieve Remote Code Execution (RCE) on the server, leading to a full system compromise. Version 3.0.4 fixes the issue.",
