ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.116.0 and 16.23.0, erpnext/selling/report/inactive_customers/inactive_customers.py accepts an unvalidated doctype filter and interpolates it into raw SQL in get_sales_details and get_last_sales_amt, allowing an authenticated user to extract sensitive information and manipulate database queries. This issue is fixed in versions 15.116.0 and 16.23.0.
