Falta de autenticação em funcionalidades críticas

O software não valida a identidade do usuário antes de executar operações sensíveis ou que consomem recursos significativos (processamento, armazenamento, banda). Qualquer pessoa, autenticada ou não, consegue acessar e usar essas funcionalidades, criando risco de abuso, consumo não autorizado de recursos ou acesso a dados protegidos.

Exemplo

Uma API de relatórios que permite gerar análises pesadas sem verificar credenciais, permitindo um atacante disparar gerações de relatório em loop para derrubar o servidor. Ou um endpoint de backup que qualquer pessoa consegue chamar sem login, expondo dados sensíveis.

Como mitigar

Implemente verificação obrigatória de identidade (autenticação) em toda funcionalidade sensível ou cara computacionalmente. Use controles de sessão, tokens JWT ou OAuth, e combine com autorização (verificar se o usuário autenticado tem permissão específica para aquela ação).
