Falta de neutralização de fórmulas em arquivos CSV

Quando um arquivo CSV é gerado com dados não sanitizados, fórmulas de planilhas (Excel, LibreOffice) podem ser injetadas. Ao abrir o arquivo, a aplicação executa a fórmula automaticamente, permitindo execução arbitrária de código ou acesso a dados sensíveis do usuário.

Exemplo

Um sistema exporta um relatório CSV com dados de clientes. Um atacante injeta no banco de dados o valor '=cmd|'/c calc'!A1', que fica no CSV. Quando um analista abre em Excel, a calculadora é executada no computador dele.

Como mitigar

Prefixe células suspeitas com aspas ou espaço (='' + formula) antes de exportar, ou use formatos seguros como ODS/XLSX com validação de fórmulas. Oriente usuários a desabilitar execução automática de macros em imports.
