pip install ethyca-fides>=2.22.1
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 ethyca-fides

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-46126, inspect your installed packages using pip:

pip show ethyca-fides

Analyze the terminal output to locate any version of Ethyca fides in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.22.1), your application is affected.

Note: The pip show ethyca-fides 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. In Ethyca fides, 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.

Source Advisory Statement

### Impact The Fides web application allows users to edit consent and privacy notices such as cookie banners. These privacy notices can then be served by other integrated websites, for example in cookie consent banners. One of the editable fields is a privacy policy URL and this input was found to not be validated. The vulnerability makes it possible to craft a payload in the privacy policy URL which triggers JavaScript execution when the privacy notice is served by an integrated website. The domain scope of the executed JavaScript is that of the integrated website. Exploitation is limited to Admin UI users with the contributor role or higher. ### Patches The vulnerability has been patched in Fides version `2.22.1`. Users are advised to upgrade to this version or later to secure their systems against this threat. ### Workarounds There are no workarounds.
