## Affected

- LabRedesCefetRJ WeGIA: fixed in 3.7.0

## Description

WeGIA is a web manager for charitable institutions. In versions prior to 3.7.0, a reflected Cross-Site Scripting (XSS) vulnerability exists in lista_arquivos_etapa.php due to improper handling of user-supplied input. The id_processo parameter is directly embedded into the HTML without sanitization, allowing attackers to inject arbitrary JavaScript. This can lead to session hijacking, credential theft, or execution of malicious actions in the context of the victim's browser. This vulnerability is fixed in 3.7.0.
