Autenticação Insuficiente ou Ausente

Quando um usuário ou sistema afirma ser quem diz que é, a aplicação não valida (ou valida mal) essa identidade antes de conceder acesso. Isso permite que um atacante se passe por outra pessoa sem fornecer credenciais válidas, obtendo privilégios indevidos.

Exemplo

Um sistema que aceita login apenas verificando um campo de e-mail na sessão (sem senha), ou uma API que confia em um identificador de usuário enviado no header HTTP sem validar um token assinado. Um atacante simplesmente muda o valor e acessa dados de terceiros.

Como mitigar

Implemente autenticação robusta: exija senha forte + MFA quando possível, valide tokens com assinatura criptográfica, revoque sessões expiradas, e nunca confie em dados controlados pelo cliente. Teste autenticação em cada endpoint crítico.
