WeGIA is an open source Web Manager for Institutions with a focus on Portuguese language users. A Stored Cross-Site Scripting (XSS) vulnerability was identified in the processa_edicao_socio.php endpoint of the WeGIA application. This vulnerability allows attackers to inject malicious scripts into the socio_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. This vulnerability is fixed in 3.2.10.
