Descriptions

This affects all versions of package html-to-csv. When there is a formula embedded in a HTML page, it gets accepted without any validation and the same would be pushed while converting it into a CSV file. Through this a malicious actor can embed or generate a malicious link or execute commands via CSV files.

Esto afecta a todas las versiones del paquete html-to-csv. Cuando se presenta una fórmula insertada en una página HTML, se acepta sin ninguna comprobación y la misma se empuja mientras es convertida en un archivo CSV. A través de esto un actor malicioso puede insertar o generar un enlace malicioso o ejecutar comandos por medio de archivos CSV
