ERPGo SaaS 3.9 CSV Injection via Vendor Creation

ERPGo SaaS 3.9 contains a CSV injection vulnerability that allows authenticated attackers to inject spreadsheet formulas into vendor name fields that execute on the workstation of users who open the exported CSV in a spreadsheet application. Attackers can add malicious formulas like =10+20+cmd|' /C calc'!A0 in the vendor creation form, which execute when the exported CSV file is opened in spreadsheet applications.
