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.
