Summary

CVE-2026-61594 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 39th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and AC-24 (Access Control Decisions) — see the control section below for these in your framework.

Vulnerability Data

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, 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. This is 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. As a workaround, gate views using djust's `login_required` / `permission_required` / `check_permissions` attributes (honored on all transports) rather than HTTP-only mixins/decorators.

Mitigating Controls (NIST 800-53 r5) AI

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

AC-24 mandates that access control decisions are applied to each request, preventing bypass of authorization logic.

AC-25 requires a tamperproof, always-invoked reference monitor that ensures authorization checks cannot be omitted.

Access enforcement requires prior authentication before any authorization decision for critical functions.

AC-6 reduces the set of actions reachable without proper authorization, limiting blast radius of missing checks.

Directly mandates unique identification and authentication of users before access to functions requiring identity.

PR.AA-01 partial match
prevents

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

PR.AA-03 partial match
prevents

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-05 partial match
prevents

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

PR.IR-01 partial match
prevents

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

prevents

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

prevents

Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.

mitigates

Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.

finds

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

prevents

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.
