pip show barbican

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-23452, inspect your installed packages using pip:

pip show barbican

Analyze the terminal output to locate any version of Barbican in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.0.0), your application is affected.

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