Impact

The live (WebSocket) transport authorizes a mount via check_view_auth, not Django's View.dispatch() chain. As a result, standard Django authorization — LoginRequiredMixin, PermissionRequiredMixin, UserPassesTestMixin, @method_decorator(login_required, name="dispatch"), and custom dispatch() guards — and the djust admin extension's staff gate (applied only in the HTTP as_view wrapper) were enforced on the initial HTTP GET but silently bypassed over WebSocket, where all events and state flow. An anonymous or under-privileged client could open a WebSocket and mount such a view — including admin list/create/change/delete — and dispatch its handlers.

Patches

Fixed in djust 1.0.7. check_view_auth now honors the Django AccessMixin family on every transport; a new system check S004 fails loud at startup on auth patterns the runtime cannot safely replay (decorator/overridden-dispatch forms); and the admin base mixin declares login_required = True + an active-staff check_permissions gate.

Workarounds

Gate views using djust's login_required / permission_required / check_permissions attributes (honored on all transports) rather than HTTP-only mixins/decorators.
