Ausência de autenticação em funcionalidades críticas

A aplicação oferece funcionalidades sensíveis ou que consomem recursos significativos (processamento pesado, armazenamento, transações) sem verificar a identidade do usuário. Qualquer pessoa, autenticada ou não, consegue acessar e executar essas operações, comprometendo confidencialidade, integridade e disponibilidade.

Example

Um serviço de geração de relatórios expõe um endpoint `/api/gerar-relatorio` que não valida token JWT ou sessão — um atacante consegue disparar dezenas de requisições simultâneas, sobrecarregando o servidor, ou acessar dados de outros clientes sem se identificar.

How to mitigate

Implemente autenticação obrigatória antes de qualquer operação sensível (valide token, sessão ou credenciais). Para APIs, use OAuth2/JWT com verificação no início da requisição; para aplicações web, enforce sessão válida. Combine com rate limiting e quotas por usuário para conter abuso de recursos.
