1. HIGH — reminders.create/updateReminder accepted clientId/interestId/
berthId from the body and persisted them with no port check; getReminder
then hydrated the row via Drizzle relations (no port filter on the
join), so a port-A user with reminders:create could exfiltrate any
port-B client/interest/berth row by guessing its UUID. New
assertReminderFksInPort gates create + update.
2. HIGH — listRecommendations(interestId, _portId) discarded portId
entirely; the route GET /api/v1/interests/[id]/recommendations
forwarded the URL id straight through. A port-A user with
interests:view could read any other tenant's recommended berths
(mooring numbers, dimensions, status). Service now verifies the
interest belongs to portId and joins berths filtered by port.
3. HIGH — Berth waiting list. The PATCH route did not pre-check that
the berth belonged to ctx.portId — a port-A user with
manage_waiting_list could reorder a port-B berth's queue. Separately,
updateWaitingList accepted arbitrary entries[].clientId and inserted
them without verifying tenancy, polluting the table with foreign-port
FKs. Both gaps closed.
4. MEDIUM — setEntityTags (clients/companies/yachts/interests/berths)
accepted any tagId and inserted into the join table. The tags table
is per-port but the join only carries a single-column FK. The
downstream getById join `tags ON join.tag_id = tags.id` has no port
filter, so a foreign tag's name + color render in the requesting port.
Helper now batch-validates tagIds belong to portId before insert.
5. MEDIUM — /api/v1/custom-fields/[entityId] PUT had no withPermission
gate (any role, including viewer, could write) and didn't validate
that the URL entityId pointed at a port-scoped entity of the field
definition's entityType. Route now uses
withPermission('clients','view'/'edit',…); service validates the
entityId per resolved entityType (client/interest/berth/yacht/company)
against portId.
Test mocks updated to cover the new entity-port-scope check.
818 vitest tests pass.
