<violation number="1" location="tracecat/authz/rbac/router.py:129">
P0: Privilege escalation vulnerability: the user-assignments mutation endpoints (create, update, delete) have no authorization scope checks. Any authenticated organization member can call these endpoints to assign themselves a high-privilege role (e.g., `organization-owner`). The previous EE implementation guarded these with `@require_scope("org:rbac:create")`, `@require_scope("org:rbac:update")`, and `@require_scope("org:rbac:delete")` plus a `_require_rbac_entitlement` dependency on the router. All of these were dropped in this move to OSS, and the `@require_scope` decorators were also removed from the corresponding service methods. At minimum, mutation operations should require an admin/owner role check to prevent any member from escalating their own privileges.</violation>

<violation number="2" location="tracecat/authz/rbac/router.py:179">
P2: The `UserRoleAssignmentReadWithDetails(...)` construction block is duplicated four times across the new endpoints. Extract a private helper function (e.g., `_assignment_to_read`) to avoid drift when the schema changes.</violation>

<violation number="3" location="tracecat/authz/rbac/router.py:233">
P2: `IntegrityError` should be caught and translated in the service layer, not the router. Catch it inside `RBACService.create_user_assignment`, roll back the session, and raise a `ValueError` with a clear message. The router should then catch `ValueError` and return HTTP 409 — consistent with the team's error-handling convention.

P2: Translate IntegrityError to ValueError so routers map this duplicate-assignment constraint to the 409 conflict path instead of a generic validation error.
