Exposição de Informação Sensível

A aplicação divulga dados sensíveis (senhas, tokens, dados pessoais, chaves) para usuários ou sistemas que não têm autorização para acessá-los. Isso acontece por falta de controle de acesso adequado, logging verboso, erro de configuração ou simplesmente porque o dado fica visível em lugares errados — como mensagens de erro, logs públicos ou respostas HTTP.

Ejemplo

Um endpoint que lista pedidos expõe o CPF de outros clientes na resposta JSON sem validar se aquele usuário tem permissão; ou uma página de erro de servidor exibe o caminho completo dos arquivos e credenciais do banco de dados; ou a API retorna tokens de sessão em histórico de navegação.

Cómo mitigar

Implemente controle de acesso baseado em papéis (RBAC), filtre sempre os dados retornados por contexto do usuário autenticado, nunca exponha informação sensível em logs ou mensagens de erro, e revise regularmente o que a API devolve em cada resposta — especialmente campos como senhas, chaves, CPFs e tokens.
