How to Fix CVE-2023-31543

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

pipreqs fixed: 0.4.12 
pip install pipreqs>=0.4.12
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 pipreqs

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-31543, inspect your installed packages using pip:

pip show pipreqs

Analyze the terminal output to locate any version of Pipreqs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.4.12), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-427: Uncontrolled Search Path Element, where the product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors. In Pipreqs, 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

A dependency confusion in pipreqs v0.3.0 to v0.4.11 allows attackers to execute arbitrary code via uploading a crafted PyPI package to the chosen repository server.
