Confiança inadequada em mecanismo de proteção implementado no cliente

O servidor delega uma função de segurança para o cliente executar, assumindo que o cliente vai implementar ou respeitar essa proteção. Na prática, o atacante controla o cliente e pode contornar ou desabilitar o mecanismo, comprometendo a segurança do servidor. É um erro fundamental de arquitetura: nunca confie em validações ou controles que rodem no lado do cliente.

Exemplo

Um servidor web que valida permissões apenas via JavaScript no navegador, permitindo ao usuário editar o HTML/JS localmente e contornar as restrições. Ou uma API que depende do cliente para não enviar dados além de um limite, sem validar no servidor.

Como mitigar

Implemente todas as validações críticas de segurança (autenticação, autorização, limite de taxa, validação de entrada) obrigatoriamente no servidor. Trate o cliente como potencialmente adversário e nunca confie em nada que venha dele sem re-validar no backend.
