SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

OAuth implementations frequently suffer from misconfigurations that enable token leakage, session hijacking, and account takeover. This Skill helps security professionals rapidly identify and document these flaws across web apps and mobile clients.

Core Features & Use Cases

  • Surface OAuth exposure: redirect_uri validation gaps, weak state/nonce handling, and token delivery vulnerabilities.
  • Guiding tests for mobile deep links and web callbacks to reproduce real-world chains.
  • Produce actionable findings with remediation guidance for developers and security teams.

Quick Start

Run the hunt-oauth workflow against a target to uncover OAuth misconfigurations and token leakage.

Frequently Asked Questions about hunt-oauth

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find OAuth misconfigurations and token leakage during a pentest?

To test OAuth redirect_uri validation gaps, you map the application's OAuth surface and attempt bypasses using open-redirect payloads and wildcard domain configurations. This Skill helps identify weak validation and documents remediation steps for secure web callbacks.

How does weak CSRF protection affect OAuth state and nonce handling?

Weak CSRF protection in OAuth state and nonce handling allows attackers to bypass authorization checks and hijack active sessions. This Skill detects missing or insufficient state validation to prevent session fixation and account takeover.

Can I use this to test OAuth mobile deep-link flows for token delivery vulnerabilities?

Yes, you can test OAuth mobile deep-link flows to identify insecure token delivery and callback vulnerabilities. This Skill guides security assessments across mobile clients to reproduce scenarios and document remediation steps for deep-link configurations.

What is the best way to document OAuth vulnerability findings for bug bounty reports?

The best way to document OAuth vulnerability findings is to map exposed surfaces, reproduce the exploit scenarios, and provide actionable remediation guidance. This Skill generates actionable findings that satisfy bug bounty requirements for detecting token leakage and misconfigurations.

Does this Skill detect open-redirect surfaces in web application OAuth implementations?

Yes, this Skill detects open-redirect surfaces in web application OAuth implementations by identifying improper redirect_uri validation. It enables testers to map surfaces and reproduce scenarios where insecure token delivery leads to token leakage.
