Divulgação de informações

Uma fraqueza que permite que dados sensíveis (credenciais, tokens, dados pessoais, detalhes técnicos do sistema) sejam expostos para um atacante ou usuário não autorizado. O risco é alto porque informações divulgadas podem ser usadas para escalar ataques ou comprometer a confidencialidade de dados críticos.

Ejemplo

Um aplicativo web que expõe stack traces com caminhos de arquivo e versões de banco de dados em mensagens de erro HTTP; ou uma API que retorna tokens JWT expirados em respostas de erro em texto plano; ou um arquivo de configuração deixado acessível publicamente contendo credenciais de banco de dados.

Cómo mitigar

Nunca exponha informações técnicas ou sensíveis em mensagens de erro, logs públicos ou respostas da aplicação — use mensagens genéricas para o usuário final. Implemente controle de acesso rigoroso, criptografe dados em repouso e em trânsito, e audite regularmente o que está sendo armazenado e acessível publicamente.
