CVE-2026-61595
HighCVSS 7.7Summary
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 and the tenant-aware QuerySet manager failed OPEN, disclosing every tenant's rows. This issue is fixed in djust 1.0.7.
Risk Assessment
Anyone holding the socket can access all tenants' rows, representing a serious breach of data isolation and confidentiality.
Recommendation
Update djust to version 1.0.7 or later.
Other vulnerabilities in djust
See all- CVE-2026-61593High
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, the SSE client→server POST endpoints are @csrf_exempt and the SSE GET stream endpoint had no Origin check, so a cross-origin page could drive a victim-cookie-authenticated SSE session and fire state-changing event handlers as the victim. This issue is fixed in 1.0.7.
- CVE-2026-61598High
A vulnerability in djust (versions prior to 1.0.7) affects the default `update_model` event handler in `ModelBindingMixin`, allowing a client to set any public, existing view attribute over the WebSocket, not just fields bound with `dj-model=`. Protection relies only on rejecting `_`-prefixed names, a 14-entry denylist of framework internals, and an optional allowlist that defaults to allowing all. As a result, an attacker can modify attributes such as `account_id`, `is_admin`, or `total_price` if they are public and exist on the view.
- CVE-2026-61590High
Prior to version 1.0.7, djust's observability endpoints expose live view/session state and a remote method-invocation surface (eval_handler). The localhost restriction was an opt-in middleware that the documented setup omits; the views themselves enforced only DEBUG. In the misconfigured-but-documented scenario (DEBUG on, middleware not installed) a non-localhost client could read live application state and invoke handlers remotely.
- CVE-2026-55571High
djust prior to 1.0.4 does not close the WebSocket or clear the view instance after denying a LiveView mount due to login or permission requirements. A WebSocket client can ignore the redirect and send events that invoke @event_handler methods without authentication, enabling unauthorized sensitive reads or mutations. This issue is fixed in version 1.0.4.
Original NVD description (English source)
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.
