Ensure that 'Python version' is the Latest Stable Version, if Used to Run the Web App

MEDIUM

Description

Description:

Periodically, newer versions are released for Python software either due to security flaws or to include additional functionality. Using the latest full Python version for web apps is recommended in order to take advantage of security fixes, if any, and/or additional functionalities of the newer version.

Rationale:

Newer versions may contain security enhancements and additional functionality. Using the latest software version is recommended in order to take advantage of enhancements and new capabilities. With each software installation, organizations need to determine if a given update meets their requirements and also verify the compatibility and support provided for any additional software against the update revision that is selected. Using the latest full version will keep your stack secure to vulnerabilities and exploits.

If your app is written using version dependent features or libraries, they may not be available on the latest version.
