RISK

Why get_card_details is rated Low

This tool retrieves sensitive financial data (PAN, CVV, expiry) but does not create, modify, delete, or move money. It is a Read operation accessing highly sensitive payment card information. High severity reflects that exposing this data could lead to fraud or unauthorized card use, despite being read-only. Audit-logging mitigates some risk but does not change the operation category.

From the tool's definition Tool name explicitly 'get_card_details' and description states it retrieves 'PAN, CVV, and expiry' — sensitive payment card data. The phrase 'Get' and 'for a card' confirms read-only retrieval operation.
