Verificação insuficiente de autenticidade de dados

A aplicação recebe dados de fontes externas (rede, arquivo, entrada do usuário) mas não valida adequadamente se eles realmente vieram de quem diz vir ou se não foram alterados no caminho. Isso permite que um atacante forje, intercepte ou modifique dados sem que o sistema detecte, comprometendo integridade e confiança.

Exemplo

Um serviço REST que confia cegamente em um campo 'user_id' vindo do cliente, sem verificar assinatura ou token, permitindo que alguém mude a URL para acessar dados de outro usuário. Ou um arquivo de configuração lido sem validar sua hash, permitindo execução de código malicioso se o arquivo for corrompido.

Como mitigar

Use mecanismos criptográficos de autenticação (HMAC, assinatura digital, certificados TLS) para garantir a origem e integridade dos dados. No lado do servidor, nunca confie em identificadores ou claims do cliente — valide contra seu próprio estado autorizado (sessão, JWT assinado, etc).
