One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.

Prompt

When auditing a GraphQL API schema for object authorization flaws, an engineer suggests checking authorization solely at the top-level Query gate before execution. How should GraphQL resolver testing be structured to detect missing access controls on nested fields and Relay nodes?

IDOR

Object-level authorization failures (BOLA/IDOR) lead to cross-account data exposure and unauthorized state changes across APIs, web, mobile, and microservices. Treat every object reference as untrusted until proven bound to the caller.

Attack Surface

Scope

Horizontal access: access another subject's objects of the same type
Vertical access: access privileged objects/actions (admin-only, staff-only)
Cross-tenant access: break isolation boundaries in multi-tenant systems
Cross-service access: token or context accepted by the wrong service

Reference Locations

Paths, query params, JSON bodies, form-data, headers, cookies
JWT claims, GraphQL arguments, WebSocket messages, gRPC messages

Identifier Forms

Integers, UUID/ULID/CUID, Snowflake, slugs
Composite keys (e.g., {orgId}:{userId})
Opaque tokens, base64/hex-encoded blobs

Relationship References

parentId, ownerId, accountId, tenantId, organization, teamId, projectId, subscriptionId

Expansion/Projection Knobs

fields, include, expand, projection, with, select, populate
Often bypass authorization in resolvers or serializers
