How to Fix CVE-2023-6022

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

prefect fixed: 2.16.5 
pip install prefect>=2.16.5
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 prefect

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-6022, inspect your installed packages using pip:

pip show prefect

Analyze the terminal output to locate any version of Prefect in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.16.5), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Prefect, 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

An attacker is able to steal secrets and potentially gain remote code execution via CSRF using a self-hosted, open source Prefect API.
