📝 Walkthrough

Walkthrough

The network-elements endpoint now accepts filter UUIDs instead of a GlobalFilter. StudyService resolves network element IDs through FilterService, then retrieves element information through the existing flow.

Changes

Filter-based network element lookup

Layer / File(s) Summary
Resolve filter IDs to network element IDs
src/main/java/org/gridsuite/study/server/service/StudyService.java, src/main/java/org/gridsuite/study/server/service/FilterService.java, src/test/java/org/gridsuite/study/server/utils/wiremock/WireMockStubs.java
StudyService requests network element IDs through FilterService. FilterService calls /v1/filters/evaluate/onlyIds with the network UUID, filter UUIDs, and an optional variant ID. WireMock helpers stub and verify that request.
Expose the filter-based endpoint
src/main/java/org/gridsuite/study/server/controller/StudyController.java, src/test/java/org/gridsuite/study/server/NetworkMapTest.java
The controller accepts a list of filter UUIDs at /network/elements-from-filters. The network map test submits the list and checks the filter lookup.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 6d105

Fetching network elements from saved filters depends on a filter-server endpoint that may not exist in the deployed version. If it is missing, the new lookup fails. Confirm the filter-server supports this endpoint before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 6d105

The network and node membership checks remain in place, and the lookup continues to use the selected network and variant. No introduced security vulnerability was established. However, authorization for the newly used filter-evaluation endpoint remains unverified, and clients must adopt the changed request contract.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The visible information-retrieval scope remains the network selected through the study/root-network/node identifiers. Whether supplied filter UUIDs can reveal information about filters outside the caller's permitted visibility depends on uninspected downstream enforcement.

Trust Boundaries and Controls

  • observed — The new adapter forwards client-supplied filter UUIDs without a local visibility check and explicitly sets only the content-type header. The inspected RestTemplate factory does not establish identity propagation, although builder customizations or external enforcement may apply.
  • observed — UUID-based filter selection predates this PR: existing public export routes accept individual or multiple filter UUIDs, and the previous lookup test supplied a genericFilter UUID. This is counterevidence to entirely new filter-selection authority, but does not establish equivalent authorization on onlyIds.

Resilience and Maintainability Implications

  • observed — The unchanged information client returns an empty JSON array for null or empty equipment IDs rather than performing an unrestricted lookup. Nonempty IDs are submitted to the selected network's elements-by-ids endpoint.

Hardening Proposals

  • proposed — Confirm the intended shared/private filter visibility model and document how onlyIds enforces it, including the trusted-caller or identity-propagation contract. Validate unauthorized UUID rejection where the model requires it.

Tests OK.

This is fine for me to use a list of filters instead of a GlobalFilter "wrapper" but I am a bit annoyed by the fact that I didn't get where the bug was coming from. Is there a problem in evaluateGlobalFilter ?

- Around line 456-458: Update the stub setup in the loop over filterUuids to
combine all IDS matchers with WireMock.havingExactly instead of repeatedly
setting the same query parameter, ensuring the stub requires every filter UUID.
Also update the related verifier to use verifyGetRequestWithMultiValueParams,
wrapping NETWORK_UUID and the IDS matchers in havingExactly to match the
multi-value parameter contract.

Ensure the deployed filter-server supports GET /v1/filters/evaluate/onlyIds.

The current upstream FilterController maps evaluation to POST /v1/filters/evaluate and POST /v1/filters/evaluate/identifiables, not this GET. If the deployed filter-server has the same mappings, requests to /network/elements-from-filters can fail during filter evaluation. Ensure the deployed service exposes this GET and returns a JSON array of strings, or change the client to use a supported endpoint.
