How to Fix CVE-2026-61588

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-2026-61588, 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. 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 When a Django `Model` instance is assigned to a **public** view attribute, djust serialized it to the client with **no sensitive-field denylist** — sending fields such as `password` (the hash), privilege flags (e.g. `is_staff` / `is_superuser`), tokens, and other PII to the browser. Because exposing model objects to templates is a normal djust pattern, this could leak credentials/PII without the developer realizing the full object crossed the wire. ### Patches Fixed in **djust 1.0.7**. Model serialization applies a secure-by-default sensitive-field denylist (password/hash/token/secret-style fields and known privilege flags are withheld) with an identity-subset fallback. ### Workarounds Keep `Model` instances on `_private` attributes and expose only the specific fields needed, until patched.
