CVE-2026-33135 Details
Description
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 <div> and outputs it to the browser. This issue has been fixed in version 3.6.7.
A reflected cross-site scripting vulnerability has been identified in WeGIA versions through 3.6.6. The issue resides in the novo_memorandoo.php endpoint, where the sccs GET parameter can be exploited to inject arbitrary JavaScript. The injected script is echoed back in the HTML response without any sanitization or encoding. This vulnerability allows attackers to execute scripts in the context of the user's browser session.
Users can upgrade to WeGIA version 3.6.7 to address this vulnerability.
