What is CVE-2026-33135?

The WeGIA web manager for charitable institutions contains a reflected cross-site scripting vulnerability in the novo_memorandoo.php endpoint. In versions 3.6.6 and earlier, an attacker is able to inject malicious JavaScript through the sccs GET parameter. The application fails to properly sanitize or encode this input, allowing the script to be rendered directly in the HTML response, potentially leading to the execution of harmful scripts in the user's browser. This security flaw has been resolved in version 3.6.7, which users are strongly encouraged to upgrade to in order to maintain their web application's security.
