Tratamento inadequado de permissões ou privilégios insuficientes

A aplicação não verifica ou não reage corretamente quando um usuário tenta executar uma ação sem as permissões necessárias. Em vez de negar o acesso de forma segura, o sistema pode ignorar a falta de permissão, executar a operação parcialmente, ou deixar dados sensíveis expostos. Isso permite que usuários não autorizados acessem ou modifiquem recursos restritos.

Ejemplo

Um portal administrativo que tenta ocultar o botão 'Deletar usuário' via CSS para usuários comuns, mas não valida permissões no backend. Um atacante remove o CSS ou chama a API diretamente e consegue deletar qualquer usuário. Ou ainda: um sistema que registra um log quando acesso é negado, mas executa 80% da operação sensível antes de verificar permissões.

Cómo mitigar

Implemente validação de permissões no servidor (nunca confie no cliente) antes de qualquer operação sensível. Use um modelo de controle de acesso (RBAC, ABAC) consistente, valide permissões em toda camada de negócio, não apenas na UI, e falhe de forma segura — rejeite completamente a operação se houver dúvida sobre privilégios.
