pip install django-sendfile2>=0.7.0
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-sendfile2

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-pcjh-6r5h-r92r, inspect your installed packages using pip:

pip show django-sendfile2

Analyze the terminal output to locate any version of Django sendfile2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Django sendfile2, 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

Similar to CVE-2022-36359 for Django, django-sendfile2 did not protect against a reflected file download attack in version 0.6.1 and earlier. If the file name used by django-sendfile2 was derived from user input, then it would be possible to perform a such an attack. A new version of django-sendfile2 will be released. Either download django-sendfile2 0.7.0 as a workaround or sanitize user input yourself, using Django's patch as a template: https://github.com/django/django/commit/bd062445cffd3f6cc6dcd20d13e2abed818fa173
