io.github.mukul975/Anthropic-Cybersecurity-Skills/testing-api-for-broken-object-level-authorization

Tests REST and GraphQL APIs for Broken Object Level Authorization (BOLA/IDOR) vulnerabilities where an authenticated user can access or modify resources belonging to other users by manipulating object identifiers in API requests. The tester intercepts API calls, identifies object ID parameters (numeric IDs, UUIDs, slugs), and systematically replaces them with IDs belonging to other users to determine if the server enforces per-object authorization. This is OWASP API Security Top 10 2023 risk API1. Activates for requests involving BOLA testing, IDOR in APIs, object-level authorization testing, or API access control bypass.

io.github.mukul975/Anthropic-Cybersecurity-Skills/testing-api-for-mass-assignment-vulnerability

The tester identifies writable endpoints, adds undocumented fields to request bodies (role, isAdmin, price, balance), and checks if the server binds these to the data model without filtering. Part of OWASP API3:2023 Broken Object Property Level Authorization. Activates for requests involving mass assignment testing, parameter binding abuse, auto-binding vulnerability, or API over-posting.
