Could you build this?

Partial The UI, scanning orchestration, and LLM agent loop are vibe-codeable, but finding authorization and business-logic flaws reliably requires deep security expertise that vibe coding alone won't supply.

What it would actually take: The orchestration layer (crawler, authenticated session handling, LLM-driven request planning, reporting UI) can be assembled with an AI assistant and existing HTTP and browser automation tools. The hard part is the vulnerability logic: modeling multi-step workflows and authorization state, avoiding false positives, and safely executing destructive tests. That needs experienced application security researchers and a large corpus of validated test cases to tune against.
