pip show Nova

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2013-0335, inspect your installed packages using pip:

pip show Nova

Analyze the terminal output to locate any version of Nova in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.0.0a0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
