  "details": "WeGIA is a web manager for charitable institutions. Versions 3.6.6 and below have a Reflected Cross-Site Scripting (XSS) vulnerability in the novo_memorandoo.php endpoint. An attacker can inject arbitrary JavaScript into the sccs GET parameter, which is directly echoed into the HTML response without any sanitization or encoding. The script /html/memorando/novo_memorandoo.php reads HTTP GET parameters to display dynamic success messages to the user. At approximately line 273, the code checks if $_GET['msg'] equals 'success'. If true, it directly concatenates $_GET['sccs'] into an HTML alert \u003cdiv\u003e and outputs it to the browser. This issue has been fixed in version 3.6.7.",
