Auth bypass in Labredescefetrj Wegia

CVE-2026-54670

WeGIA is a web manager for charitable institutions. Prior to 3.8.5, the contribution request dispatcher in web/html/contribuicao/controller/control.php accepts attacker-controlled nomeClasse and metodo values without a complete controller and method allowlist, exempts sensitive ContribuicaoLogController operations from authentication, and constructs a controller include path without canonical directory containment. An unauthenticated remote attacker can invoke getContribuicoesLogJSON, sincronizarStatus, registrarFaturas, and other sensitive methods to disclose contribution and donation records or trigger financial workflow operations. A traversal-shaped nomeClasse value can also cause require_once to include an accessible PHP or configuration file outside the intended controller directory, exposing source code, credentials, or other sensitive local data. This issue is fixed in version 3.8.5.
