Divulgação de Informações Sensíveis

A aplicação expõe dados sensíveis (senhas, tokens, chaves criptográficas, dados pessoais) através de canais inseguros ou em contextos onde não deveria — logs, mensagens de erro, cache, memória ou tráfego de rede desencriptado. O risco é um atacante interceptar ou acessar esses dados e comprometer contas, sistemas ou privacidade.

Example

Uma API retorna a senha do usuário em texto plano dentro de um JSON de resposta de erro; um servidor expõe tokens de autenticação em arquivos de log acessíveis publicamente; uma página web carrega chaves de API dentro de variáveis JavaScript visíveis no código-fonte.

How to mitigate

Nunca exponha dados sensíveis em logs, mensagens de erro visíveis ao usuário ou código cliente. Criptografe dados em trânsito (HTTPS/TLS), use variáveis de ambiente ou vaults para armazenar credenciais, e revise regularmente o que é registrado ou retornado em respostas. Implemente redação de dados sensíveis (masking) em logs e erros.
