Manipulação de identificador para acessar dados de outro usuário

A aplicação não valida adequadamente se o usuário autenticado tem permissão para acessar o recurso solicitado, permitindo que modifique parâmetros (como IDs) para acessar dados alheios. Por exemplo, ao mudar o ID de um pedido na URL de 123 para 456, consegue visualizar pedidos de outros clientes sem controle de acesso real.

Example

Um banco digital permite acessar extratos via URL /extrato?conta_id=5000. Se um usuário muda para conta_id=5001, consegue ver o extrato de outra pessoa apenas porque a aplicação valida apenas autenticação, não autorização específica para aquele recurso.

How to mitigate

Implemente verificação de autorização em cada acesso a recurso: valide se o usuário autenticado de fato possui permissão para aquele ID específico, comparando contra dados da sessão ou banco de dados. Use abstração (ex: 'minha conta' em vez de IDs diretos) e evite expor identificadores sequenciais previsíveis.
