A Business Logic vulnerability exists in SourceCodester Pharmacy Product Management System 1.0 in the add-stock.php file. The application fails to validate the "txtprice" and "txttotalcost" parameters during stock entry, allowing negative financial values to be submitted. This leads to corruption of financial records, allowing attackers to manipulate inventory asset values and procurement costs.
