Confusão de Tipos

Ocorre quando o código trata um objeto como se fosse de um tipo diferente do seu tipo real, contornando verificações de tipo ou explorando conversões implícitas. Isso permite ao atacante executar operações não autorizadas, acessar memória indevida ou ganhar controle de execução.

Ejemplo

Um navegador interpreta um objeto JavaScript como um array e acessa propriedades além dos limites esperados; ou um objeto C é reinterpretado como um tipo com layout de memória diferente, lendo dados sensíveis adjacentes ou escrevendo em endereços não autorizados.

Cómo mitigar

Validar rigorosamente tipos antes de operações críticas (type checking explícito em runtime), evitar casts inseguros, usar linguagens com type safety forte, e aplicar análise estática para detectar conversões perigosas. Em C/C++, preferir safe casts e checked access patterns.
