WeGIA is an open source web manager with a focus on the Portuguese language and charitable institutions. Versions prior to 3.4.5 have a SQL Injection vulnerability in the endpoint `/WeGIA/html/socio/sistema/processa_deletar_socio.php`, in the `id_socio` parameter. This vulnerability allows the execution of arbitrary SQL commands, which can compromise the confidentiality, integrity, and availability of stored data. Version 3.4.5 fixes the issue.
