Controle de Fluxo Insuficiente

É quando o código não valida ou não controla adequadamente quais caminhos de execução podem ser seguidos, permitindo que o programa execute instruções indesejadas ou pule validações críticas. Acontece quando faltam verificações de precondições, estado da aplicação ou permissões antes de executar operações sensíveis.

Exemplo

Um sistema de autenticação que verifica a senha, mas não valida se o usuário ainda está ativo ou se sua sessão expirou antes de conceder acesso a dados sensíveis. Ou um aplicativo que executa uma transação financeira sem confirmar se o estado da conta permite tal operação.

Como mitigar

Implemente validações explícitas de estado e permissões em todos os pontos críticos do código; use máquinas de estado para operações sensíveis e realize testes de caminhos de execução alternativos para detectar saltos indevidos no fluxo esperado.
