SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps security teams discover undocumented, hidden, or forgotten API endpoints and abuse vectors by applying targeted fuzzing against live applications.

Core Features & Use Cases

  • Endpoint discovery fuzzing using tailored wordlists and both unauthenticated and authenticated paths.
  • Parameter fuzzing to reveal hidden query parameters and potential security gaps.
  • Mass operations abuse, resource exhaustion testing, and error message enumeration to assess resilience.
  • Threat modeling and reverse engineering approaches (STRIDE) integrated into the fuzzing workflow.

Quick Start

Provide a target URL and, if needed, an access token, then run the fuzzing workflow to begin endpoint discovery and vulnerability exploration.

FAQPage Schema
How do I discover hidden API endpoints through fuzzing?

API endpoint discovery fuzzing identifies undocumented or forgotten paths by applying targeted fuzzing against a target URL using tailored wordlists. It tests both unauthenticated and authenticated routes to reveal hidden endpoints and potential security gaps.

Can I run API fuzzing against a FastAPI or Node.js backend?

Yes, API fuzzing operates across multiple backend stacks including FastAPI, Node.js, Django, Rails, Spring, .NET, PHP, Go, Supabase, Firebase, or custom backend architectures to discover hidden paths.

What's the best way to test for mass operations abuse and resource exhaustion in APIs?

The best way to test mass operations abuse and resource exhaustion is through configurable API fuzzing workflows that apply targeted parameter fuzzing and data collection to assess application resilience and enumerate error messages.

How does threat modeling integrate with API endpoint discovery?

Threat modeling integrates with API endpoint discovery by applying the STRIDE framework directly into the fuzzing workflow, enabling structured behavioral analysis and reverse engineering to identify potential abuse vectors.

Do I need an access token to fuzz authenticated API paths?

You need to provide an access token if you want the fuzzing workflow to discover hidden endpoints and parameters along authenticated API paths, alongside standard unauthenticated endpoint enumeration.

What limitations should I consider when fuzzing custom backend API paths?

When fuzzing custom backend API paths, limitations depend on the accuracy of your provided wordlists and the specific error handling configurations of the target application, which affect behavioral analysis and structured reporting outputs.
