How to Fix CVE-2025-54384

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

ckan fixed: 2.11.4 
pip install ckan>=2.11.4
ckan fixed: 2.10.9 
pip install ckan>=2.10.9
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 ckan

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-54384, inspect your installed packages using pip:

pip show ckan

Analyze the terminal output to locate any version of Ckan in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.11.4), your application is affected.

Note: The pip show ckan 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 Ckan, 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 `helpers.markdown_extract()` function did not perform sufficient sanitization of input data before wrapping in an HTML literal element. This helper is used to render user-provided data on dataset, resource, organization or group pages (plus any page provided by an extension that used that helper function), leading to a potential XSS vector. ### Patches This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4
