nopCommerce 4.10 and 4.80.3 CSV export enables formula injection via unsanitized input; executes.

Code
nopCommerce versions v4.10 and v4.80.3 are vulnerable to *C*SV Injection
    (Formula Injection) when exporting data to CSV. The application does not
    properly sanitize user-supplied input before including it in CSV export
    files.
    
    An attacker can inject malicious spreadsheet formulas into fields that will
    later be exported (for example, order details, product names, or customer
    information). When the exported file is opened in spreadsheet software such
    as Microsoft Excel or LibreOffice Calc, the injected formula is executed.
