What calculate_financing does on FalaZuki Finance BR

Why calculate_financing is rated Low
Even though calculate_financing only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
