I’m making an Excel handler to save Excel content in a database.
I’m using MemoryStream to read the files content and make the validations and inserts.
My question is, if the Excel file that is used is somehow infected by a virus, can it infect the server with this procedure? I’m not storing it anywhere in the server, just reading it with MemoryStream and then handling it with XSSFWorkbook.

I want to know if I still would have to check the file for virus before handling it this way. I think not, because it’s not being “written” in the server this way, I’m just reading it IRT, and copying to MemoryStream.
