📝 WalkthroughWalkthroughThe ACL inheritance endpoint now requires an authenticated user and conditionally applies ETAC graph filtering. Tests add user context, dogtag configuration, graph fixtures, and ETAC-enabled and disabled scenarios. ChangesACL inheritance endpoint
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The endpoint can perform graph enumeration and traversal before authentication is enforced, allowing unauthenticated access to authorization-sensitive work. This security risk remains unresolved and should be fixed before merging. Sequence Diagram(s)sequenceDiagram

Authenticate before graph lookups.
Lines 138-143 run edge lookup, ACL path traversal, and display-kind retrieval before this check. An unauthenticated caller can distinguish graph lookup errors from the final 403, which exposes object existence and permits unauthenticated traversal work. Retrieve and reject the user before parameter-dependent graph access.

891-891: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the shared mock setup for the two ETAC cases.
The mock setup in the ETAC-enabled case and the ETAC-disabled case is duplicated almost verbatim. Only the dogtag override and the expected body differ. Move the fixtures and the two
ReadTransactionexpectations into a helper, then call it from bothsetupMocksfunctions. This keeps both cases in sync when the graph fixtures change.Also applies to: 998-998

Description
Added ETAC filtering logic to /api/v2/graphs/acl-inheritance endpoint
Motivation and Context
Resolves BED-9120
Filtering was not being applied to users with ETAC enabled not restricting response data (cross-domain).
How Has This Been Tested?
Test written, also tested in Bruno.
