## Technical details

A broken access control vulnerability exists in SourceCodester Pharmacy Sales and Inventory System 1.0 within the 'sell_statement' and 'supplier_payment' functions of 'application/controllers/ShowForm.php'. The root cause is a logical error in the authentication check where an OR operator (||) is used instead of an AND operator (&&) when validating session data. This flaw causes the authorization condition to always evaluate to true, allowing unauthenticated remote attackers to bypass login requirements. Successful exploitation allows an attacker to access the 'sales_product' database table and view sensitive financial information, including invoice numbers, unit prices, and revenue totals.
