How to Fix CVE-2026-61596

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-2026-61596, 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-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. 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 djust's per-object authorization (`get_object` + `has_object_permission`, ADR-017) was enforced on the WebSocket **mount** and **event** paths but **not** on three other render entry points: (a) the initial **HTTP GET** render, (b) **SPA `url_change`** navigation, and (c) `{% live_render %}` **embedded child** views. An authenticated user could therefore view (and on some paths act on) an object they are not authorized for by loading the page directly, navigating to it via SPA url-change, or composing it as an embedded child — a classic IDOR / broken object-level access control on object-scoped views. ### Patches Fixed in **djust 1.0.7**. All render entry points now route through a shared `enforce_object_permission` chokepoint: HTTP GET returns **403**, `url_change` emits a `permission_denied` frame and skips the render, and `{% live_render %}` (eager + lazy) refuses the embed. Views without a custom `get_object` are unaffected (no-op). ### Workarounds No reliable workaround short of upgrading. Do not expose object-scoped views through the HTTP-GET / url_change / live_render paths until patched.
