SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill identifies security vulnerabilities in FastAPI applications by auditing endpoint files for missing authentication, input validation, weak error handling, and rate limiting.

Core Features & Use Cases

  • Security Auditing: Systematically scans FastAPI endpoint files for common security gaps.
  • Vulnerability Detection: Identifies endpoints without authentication, missing input validation, poor error handling, and lack of rate limiting.
  • Risk Assessment: Categorizes vulnerabilities by severity and provides actionable findings.
  • Use Case: When reviewing a FastAPI application for security issues or preparing for deployment.

Quick Start

Run the audit for the 'app/api' directory: fastapi-endpoint-security-audit --dir /path/to/app/api/

FAQPage Schema
How do I audit FastAPI endpoints for security vulnerabilities?

To audit FastAPI endpoint security, scan your application's endpoint files to identify missing authentication, input validation, error handling, and rate limiting. This process categorizes vulnerabilities by severity and provides actionable findings for remediation.

What security vulnerabilities should I check for in my FastAPI application?

Common FastAPI security vulnerabilities include endpoints without authentication dependencies, missing input validation via pydantic constraints, poor exception safety, and a lack of rate limiting. Scanning source code systematically detects these specific security gaps.

How do I check if my FastAPI endpoints are missing authentication and rate limiting?

Checking FastAPI endpoints for missing authentication and rate limiting requires auditing the source code for auth dependencies and request throttling implementations. A dedicated security scanner categorizes these missing protections as vulnerabilities by severity.

Can I use a security scanner to find missing pydantic input validation in FastAPI?

Yes, a FastAPI security scanner can identify missing pydantic input validation by checking endpoint files for appropriate pydantic constraints. It systematically reviews source code patterns to detect where input validation is absent.

Does FastAPI security auditing require access to the application source code?

Yes, FastAPI security auditing requires direct access to the application source code and a thorough understanding of its patterns. The scanner analyzes endpoint files directly to detect missing auth, validation, and error handling mechanisms.
