How to Fix CVE-2022-46147

To remediate this vulnerability, upgrade all affected Xblock drag and drop v2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

xblock-drag-and-drop-v2 fixed: 3.0.0 
pip install xblock-drag-and-drop-v2>=3.0.0
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 xblock-drag-and-drop-v2

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-46147, inspect your installed packages using pip:

pip show xblock-drag-and-drop-v2

Analyze the terminal output to locate any version of Xblock drag and drop v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0), your application is affected.

Note: The pip show xblock-drag-and-drop-v2 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Xblock drag and drop v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
