CVE-2026-54767 — WeGIA: Hardcoded Secret Key Backdoor — Mass Data Destruction via deletar_socios.php

WeGIA is a web manager for charitable institutions. Prior to 3.8.5, web/html/socio/sistema/controller/deletar_socios.php exposes an unauthenticated GET endpoint whose chave parameter is checked only against a hardcoded chave_correta value embedded in the public source repository. A remote attacker who obtains that value can reach the endpoint's TRUNCATE TABLE operations for the endereco, pessoafisica, pessoajuridica, and socio tables without an administrative session or application authorization, permanently destroying member and contributor records. The attack requires the affected tables to exist and the web process database account to possess truncation privileges. This issue is fixed in version 3.8.5.
