How to Fix CVE-2026-61594

To remediate this vulnerability, upgrade all affected Djust dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

djust fixed: 1.0.7 
pip install djust>=1.0.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show djust

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-61594, inspect your installed packages using pip:

pip show djust

Analyze the terminal output to locate any version of Djust in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.7), your application is affected.

Note: The pip show djust command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-306: Missing Authentication for Critical Function, where the product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. In Djust, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
