pip install cloudtoken>=0.1.24
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 cloudtoken

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2018-13390, inspect your installed packages using pip:

pip show cloudtoken

Analyze the terminal output to locate any version of Cloudtoken in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.24), your application is affected.

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

Technical Details
