Confusão de Tipo

Fraqueza onde o código trata um dado como se fosse de um tipo diferente do que realmente é, resultando em comportamento imprevisto e potencialmente perigoso. Um atacante pode explorar essa confusão para contornar validações, corromper memória ou executar código arbitrário.

Exemplo

Um navegador recebe um objeto JSON que deveria ser uma string, mas trata como um número inteiro para cálculos de offset em memória — ao somar um valor grande, o atacante causa leitura/escrita fora dos limites do buffer alocado.

Como mitigar

Sempre validar e converter explicitamente o tipo de dados na entrada, usando type checking ou casting seguro. Em linguagens com tipagem dinâmica (JavaScript, Python), adicione verificações de tipo antes de operações críticas; em linguagens compiladas, ative warnings de compilador para conversões implícitas suspeitas.
