How to Fix CVE-2020-17495

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

django-celery-results fixed: 2.4.0 
pip install django-celery-results>=2.4.0
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 django-celery-results

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2020-17495, inspect your installed packages using pip:

pip show django-celery-results

Analyze the terminal output to locate any version of Django celery results in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.0), your application is affected.

Note: The pip show django-celery-results command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-312: Cleartext Storage of Sensitive Information, where the product stores sensitive information in cleartext within a resource that might be accessible to another control sphere. In Django celery results, 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

django-celery-results prior to 2.4.0 stores task results in the database. Among the data it stores are the variables passed into the tasks. The variables may contain sensitive cleartext information that does not belong unencrypted in the database. In version 2.4.0 this is no longer the default behaviour but can be re-enabled with the `result_extended` flag in which case care should be taken to ensure any sensitive variables are scrubbed - see [here](https://github.com/celery/django-celery-results/issues/154#issuecomment-734706270) for an example.
