How to Fix CVE-2014-0157

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

horizon fixed: 2013.2.4 
pip install horizon>=2013.2.4
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 horizon

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2014-0157, inspect your installed packages using pip:

pip show horizon

Analyze the terminal output to locate any version of Horizon in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2013.2.4), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
