README

Excerpt

Testing API for Broken Object Level Authorization

When to Use

Assessing REST or GraphQL APIs that use object identifiers in URL paths, query parameters, or request bodies
Performing OWASP API Security Top 10 assessments where API1:2023 (BOLA) must be tested
Testing multi-tenant SaaS applications where users from different tenants should not access each other's data
Validating that API endpoints enforce per-object authorization checks beyond just authentication
Evaluating APIs after new endpoints are added to ensure authorization middleware is applied consistently

Do not use without written authorization from the API owner. BOLA testing involves accessing or attempting to access other users' data, which requires explicit permission.
