Modificação descontrolada de atributos dinâmicos de objetos

Ocorre quando a aplicação permite que usuários modifiquem atributos de objetos sem validação adequada, especialmente em linguagens que permitem criar propriedades dinamicamente (como Python, JavaScript, PHP). Um atacante consegue injetar ou sobrescrever atributos críticos — flags de admin, valores monetários, referências internas — alterando o comportamento da aplicação.

Exemplo

Um sistema em Python recebe JSON do usuário e faz `user.__dict__.update(request.json)` para popular dados de perfil. O atacante envia `{"is_admin": true}` e ganha privilégios sem autorização, porque nenhuma validação protege qual atributo pode ser modificado.

Como mitigar

Use listas explícitas de propriedades permitidas (whitelist) para update de objetos. Separe dados de entrada (DTO/schema) de modelos internos, mapeando apenas campos seguros. Nunca faça merge direto de entrada de usuário em atributos de objetos críticos.
