1. HIGH — Socket.IO accepted client-supplied `auth.portId` in the
handshake without verifying the user actually held a role in that
port, then unconditionally joined the socket to `port:${portId}`.
The `join:entity` handler also skipped authorization. This let any
authenticated CRM user receive realtime events from any other
tenant: invoice numbers + totals + client names, document signer
emails, registration events with full client name + berth, file
uploads, etc. Auth middleware now resolves the user's
userPortRoles (or isSuperAdmin) before honouring portId, and
join:entity verifies the entity's port matches a port the user
has access to. Pre-existing pre-branch issue but fixed here given
the explicit "all data is extremely sensitive" directive.
2. MEDIUM — listCrmInvites issued a global SELECT with no port
scope. The crm_user_invites table has no portId column (invites
mint global better-auth users, then port roles are assigned
later). The previous gating on per-port admin.manage_users let
any director enumerate every other tenant's pending invitee
emails + isSuperAdmin flags — a phishing target list and a
super-admin onboarding timing oracle. Restrict GET (list),
DELETE (revoke), and POST resend to ctx.isSuperAdmin.
