Lab 401 — InsightPulse — Broken Authorization on AI Chat Agent API

hackadvisor

Task: InsightPulse analytics platform with AI Chat Agent feature denied by permission profile; UI disables input and shows Access Restricted banner. Solution: Discover actual API endpoint /api/v1/chat/agent from chat.js, call it directly with curl bypassing client-side restriction — backend only checks authentication, not authorization.
