CVE-2026-42870 — WeGIA: Cross-Site Scripting (XSS) Stored endpoint 'informacao_adicional.php' parameter 'descricao'

WeGIA is a web manager for charitable institutions. In versions prior to 3.7.0, a Stored Cross-Site Scripting (XSS) flaw was identified at the following endpoint: funcionario/profile_funcionario.php?id_funcionario=2. By injecting a malicious payload into the 'Description' (Descrição) field and saving the profile, the script becomes persistently stored. The payload is subsequently executed whenever the profile page is accessed. This vulnerability is fixed in 3.7.0.
