pdf-image (npm package) through version 2.0.0 allows OS command injection via the pdfFilePath parameter. The constructGetInfoCommand and constructConvertCommandForPage functions use util.format() to interpolate user-controlled file paths into shell command strings that are executed via child_process.exec()
