Business Integrity — Policy Overriding — Discounts

Description:

Tricking the AI into granting unauthorized discounts, waiving fees, applying special coupon codes, or issuing store credit outside of approved policies.

Scope & Assumptions

• Model can interact with pricing, checkout, or billing systems.

• Lack of secondary verification allows prompt-only authority claims.

Attack Surfaces

• Checkout bots

• Billing assistants

• Customer support AI with refund/discount permissions
