SQL Injection in Labredescefetrj Wegia

CVE-2026-55684

WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the unauthenticated web/html/socio/sistema/cadastro_cobrancas_geracao.php endpoint accepts form-encoded POST data through extract($_REQUEST) and interpolates codigo, descricao, data_emissao, data_vencimento, data_pagamento, valor, valor_pago, status, link_cobranca, link_boleto, linha_digitavel, and id_socio into a raw INSERT statement. Numeric parameters are unquoted and unvalidated, while string parameters can break out of their single-quoted SQL context. A remote attacker can execute arbitrary SQL to read or modify billing, member, employee, permission, and credential data or to delete database tables. This issue is fixed in version 3.8.6.
