What this covers
Test the workflow the way an abuser would, not one request at a time.
Business-logic failures live in sequences, state transitions and assumptions that signature-based scanners cannot understand.
01Why endpoint checks miss it
- Each request can be syntactically valid while the overall workflow violates a business rule.
- Role changes, retries, concurrency, limits and out-of-order actions create state a single-request test never sees.
- Generic payload libraries do not understand what a transfer, approval, entitlement or recovery flow is meant to guarantee.
02How ThreatCanary tests the workflow
- Build a sequence model from observed API behaviour, roles, objects and application context.
- Generate explicit abuse hypotheses around state, authority, value limits and cross-account access.
- Execute controlled multi-step tests while preserving request order, identity and state evidence.
03What teams receive
- The legitimate workflow and the exact deviation that produced the unauthorised result.
- Reproducible requests, identities, object references and state transitions.
- A remediation recommendation tied to the broken invariant rather than a generic vulnerability label.
