    API6:2023 - Unrestricted Access to Sensitive Business Flows

    Business-critical flows without anti-automation controls can be abused at scale.

    Why This Category Exists

    Some workflows are valid individually but harmful when automated: coupon redemption, password reset requests, checkout attempts, account creation, or payout actions. Abuse controls must be flow-aware.

    Common Impact

    • Fraud, scraping, and business logic abuse.
    • Inventory or promotion abuse during campaigns.
    • Operational and financial losses.

    Prevention Checklist

    • Apply per-flow limits, challenge mechanisms, and anomaly detection.
    • Use idempotency keys and replay protection for sensitive actions.
    • Require step-up authentication for high-risk operations.
    • Monitor flow metrics and block suspicious automation behavior.
