How to Fix CVE-2014-8650

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

requests-kerberos fixed: 0.6 
pip install requests-kerberos>=0.6
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 requests-kerberos

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2014-8650, inspect your installed packages using pip:

pip show requests-kerberos

Analyze the terminal output to locate any version of Requests kerberos in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.6), your application is affected.

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