Manipulação de identificadores para contornar controle de acesso

A aplicação não valida adequadamente se o usuário autenticado tem permissão para acessar o recurso identificado pelo parâmetro fornecido (ID de registro, número de documento, etc.). Um atacante modifica esse parâmetro para acessar dados de outros usuários — por exemplo, mudando `user_id=123` para `user_id=124` na URL e obtendo informações alheias sem autenticação adicional.

Exemplo

Um banco permite visualizar extrato em `/api/extrato?conta=1001`. Um cliente autenticado como `user_123` descobre que pode acessar `/api/extrato?conta=1002` e ver o extrato completo de outra pessoa, porque o servidor apenas verifica se há uma sessão válida, não se aquele usuário é dono da conta 1002.

Como mitigar

Implemente validação de propriedade em cada requisição: antes de retornar dados, confirme que o ID do recurso pertence ao usuário autenticado. Use referências indiretas (tokens opacos) em vez de IDs sequenciais previsíveis, e aplique testes automatizados que tentam acessar recursos de outros usuários.
