--- name: business-logic-vuln description: >- Entry P1 category router for business logic testing. Use when workflow abuse, race conditions, pricing flaws, or multi-step state attacks matter more than parser-level input injection. --- # Business Logic Router This is the routing entry point for business-logic and state-machine issues. ## When to Use - The target involves coupons, inventory, payment, approvals, quotas, invites, trials, or state transitions - The issue is not parser-level; it is about when checks happen and which business conditions are checked - You suspect race conditions, workflow bypass, price tampering, negative values, stacked discounts, or multi-step flaws ## Skill Map - [Business Logic Vulnerabilities](../business-logic-vulnerabilities/SKILL.md) ## Recommended Flow 1. First map key business states and one-time actions 2. Then check for check-then-act windows, sequence dependencies, or missing cross-step authorization 3. If the chain depends on APIs, uploads, or object permissions, return to the corresponding router skill to complete the path ## Related Categories - [api-sec](../api-sec/SKILL.md) - [auth-sec](../auth-sec/SKILL.md) - [file-access-vuln](../file-access-vuln/SKILL.md)
