WeGIA is an open source web manager with a focus on the Portuguese language and charitable institutions. A Stored Cross-Site Scripting (XSS) vulnerability was identified in the adicionar_enfermidade.php endpoint of the WeGIA application prior to version 3.4.5. This vulnerability allows attackers to inject malicious scripts into the nome parameter.

The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk. Version 3.4.5 fixes the issue.
