Entity assessments inherit custom-field support. Serializers handle custom-field values and validate folder selection against the effective perimeter. Cache handling and API tests cover updates, folder changes, authorization, and cloning. The frontend form and schema support entity-assessment custom fields. |
Assessment labels, filtering, and exports backend/custom_fields/filters.py, backend/app_tests/api/test_api_custom_fields.py, backend/tprm/views.py, frontend/src/lib/utils/{crud.ts,table.ts}, product-docs/concepts/third-party-risk.md |
The viewset supports custom-field search and filtering, prepares visible labels for export, and copies labels and custom-field values when cloning. Custom-field filtering deduplicates results. Assessment lists include label fields and batch actions. Documentation describes assessment labels and revision carry-over. |

The duplicate-filtering concern is addressed, and no actionable merge-blocking issue remains. The change is ready to merge after normal checks.
Security Architecture Review
-
Security architecture risk: 🟡 Moderate · up to
1e0acThe new metadata paths have two bounded security risks: filtering can reveal an assessment’s membership in a hidden label, and perimeter changes can preserve custom-field values outside their intended domain. Assessment permissions, related-field masking and transactional updates limit exposure, but do not resolve these risks.
Retained concerns
- Medium · security · inferred: An authenticated caller who can read assessments and knows a valid inaccessible label ID can filter by that label and infer membership from returned assessment rows. The generic relation filter uses all label objects; subsequent list/export masking hides label values but preserves the selected rows. This assessment-specific disclosure path is introduced by the PR.
- Medium · security · inferred: A perimeter-driven folder move can validate submitted custom fields against the source folder, delete out-of-scope values after moving, then recreate those same values. The read property returns all stored values without rechecking definition applicability, so source-domain metadata can remain visible to destination assessment readers. Destination required-field checks can also be skipped. This interaction is newly reachable through entity-assessment custom-field support; the underlying perimeter-to-folder ordering is pre-existing.
Security review details
-
Security Blast Radius
- inferred — The label-filter disclosure is bounded to assessments the caller can already read and requires a valid label identifier. It reveals association membership, not the hidden label’s text or otherwise unauthorized assessment rows. Custom-field transition exposure depends on an allowed assessment mutation, applicable source definitions and subsequent destination readers.
Security Findings and Attack Paths
- inferred — The two supported static paths are hidden-label predicate disclosure before masking, and source-scoped custom-field reapplication after a perimeter-derived move. Neither was exercised end to end. The supplied line-1310 candidate remains deferred, with no retained verified Security findings in the brief.
Trust Boundaries and Controls
- observed — Assessment rows remain authorization-scoped. Export formatting receives the visibility-filtered label list. New many-to-many links are checked for related-object visibility, while already-linked hidden objects may be retained. Explicit folder moves invoke destination add-permission validation; perimeter-derived assignment occurs later, in a pre-existing update branch.
Resilience and Maintainability Implications
- inferred — Transactions should contain database failures during assessment metadata writes and clone creation, but cannot correct successful writes validated against the wrong folder. Bulk relation additions/removals are set-based and repeatable without concurrent changes; concurrency can still overwrite intervening relation edits. No security enforcement role for these labels was established.
Hardening Proposals
- proposed — Authorize related-label filter predicates before queryset selection, using the same visibility policy as list and export masking, so inaccessible identifiers cannot select assessment rows.
- proposed — Resolve the effective destination folder before authorization and custom-field validation, then use that same folder for required-field checks, cleanup and value application. Recheck applicability at the persistence boundary to prevent stale pending values from defeating cleanup.

- Around line 506-510: Update the partial-update flow around the serializer’s
requested-folder check and Assessment.save() so unrelated PATCHes preserve the
existing root folder and suppress the save-time fallback. Keep the fallback for
creation and explicit folder or perimeter changes, and continue normalizing the
effective folder before custom-field validation for explicit moves; do not treat
an existing Global assessment alone as a folder-change request.

Sorry, something went wrong.
@coderabbitai Both out of scope. The implicit move already happens through Assessment.save() without a permission check, and validating it would 403 every edit (labels included) on legacy Global rows. For the form, Global definitions stay valid in child domains and a missing required field returns a normal 400, so a submit guard while definitions load would belong in CustomFieldsSection for all hosts. |

What & why
Entity assessments can now carry custom fields and filtering labels. Labels can also be shown as a list column, filtered on, added or removed in bulk, and appear in the CSV/Excel export; custom fields get the same list columns and filters as other objects but are not in the export.
