CyberRota Analysis
AI-GeneratedA vulnerability exists in the djust library prior to version 1.0.7, where tenant isolation is improperly enforced during WebSocket and SSE connections, leading to unauthorized access to data across different tenants. This flaw allows attackers to retrieve unfiltered query results, potentially exposing sensitive information. Organizations using djust for Django applications, particularly those implementing multi-tenancy, should prioritize upgrading to version 1.0.7 to mitigate this risk.

Original NVD Description
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, `djust.tenants` isolation was enforced only on the HTTP path. The current tenant was stored in `threading.local()` and set exclusively by the HTTP-only `TenantMiddleware`, so on the live (WebSocket/SSE) path `get_current_tenant()` was always `None` during mount and every event handler — and the tenant-aware `QuerySet` manager failed OPEN (returned the unfiltered queryset, ignoring `STRICT_MODE`), disclosing every tenant's rows to whoever held the socket. `threading.local` was additionally shared across connections on the `sync_to_async` executor thread. This issue is fixed in djust 1.0.7. Tenant storage moved to a `contextvars.ContextVar` (per async task); the resolved tenant is bound around WS/SSE mount and every dispatch; both managers scope the base queryset once and fail CLOSED (`.none()` under the default `STRICT_MODE`); and system check S006 warns when `STRICT_MODE=False`. No known workarounds are available on the live path.
