SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the critical security risk of Broken Function Level Authorization (BFLA), where lower-privilege users can access administrative or restricted functions due to improper server-side enforcement.

Core Features & Use Cases

  • Role-Based Matrix Validation: Systematically tests endpoint reachability across different privilege levels to identify unauthorized access.
  • Multi-Vector Probing: Checks for vulnerabilities across API versions, HTTP method overrides, path normalization, and content-type switching.
  • Use Case: A security researcher uses this skill to verify that a standard user account cannot trigger administrative DELETE or PATCH operations on an API by manipulating headers or path segments.

Quick Start

Use the access-bfla skill to audit the target API by providing the scope definition and the required role-based endpoint matrix for validation.

FAQPage Schema
How do I test for broken function level authorization in APIs?▼

To test for broken function level authorization, you validate API endpoints against multiple privilege roles and request manipulation vectors to detect unauthorized access to administrative or state-changing functions.

What is broken function level authorization and how does it impact API security?▼

Broken function level authorization occurs when lower-privilege users access administrative or restricted functions due to improper server-side enforcement, creating critical security risks for REST, GraphQL, and gRPC services.

Can I audit GraphQL and gRPC endpoints for unauthorized access using this method?▼

Yes, you can audit GraphQL and gRPC endpoints for unauthorized access. This approach validates function-level authorization boundaries by testing endpoint reachability across different privilege levels.

How do I perform a role-based matrix validation to identify unauthorized API access?▼

Role-based matrix validation systematically tests endpoint reachability across different privilege levels to identify unauthorized access, requiring a defined scope and a role-based endpoint matrix for validation.

What request manipulation vectors are used to detect API function-level authorization vulnerabilities?▼

Multi-vector probing checks for vulnerabilities across API versions, HTTP method overrides, path normalization, and content-type switching to detect function-level authorization vulnerabilities.

What scope and authorization caching protocols are required for a BFLA security audit?▼

A BFLA security audit requires strict adherence to defined scope, authorization caching, and evidence-based reporting protocols to ensure accurate validation of function-level authorization boundaries.
