FlowFuzzer

FlowFuzzer is a web app (with an optional CLI) that tests real user journeys to uncover authorization and business-logic flaws—IDORs, privilege escalation, broken workflow steps, and “can’t happen” states that do happen. Instead of only crawling endpoints, it records multi-step flows (login, checkout, refunds, admin actions) and then mutates parameters, roles, and sequence order to see what the server actually allows. It integrates with staging environments and CI to run regression “abuse tests” on every release. The product is brutally focused: fewer findings, higher confidence, and reproducible proof steps developers can fix fast. It won’t replace full pentests, and it won’t magically understand every custom app, but it can reliably catch the common high-impact logic failures that slip past SAST/DAST and code review.
