RISK

Why update_buy_request is rated Medium

This tool modifies existing buy request records by updating draft fields. Since it targets draft fields specifically, the changes appear reversible and not destructive. However, given the financial context (purchase/procurement operations) and the potential to alter purchase obligations before approval, this rates medium severity.

From the tool's definition Tool name 'update_buy_request' and description 'Update editable draft fields on a Sanka Buy request' indicate modification of purchase request data. The term 'update' combined with 'draft fields' shows reversible data changes.
