How to Fix CVE-2026-55630

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

kiwitcms fixed: Latest secure release 
pip install kiwitcms>=Latest secure release
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 kiwitcms

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-55630, inspect your installed packages using pip:

pip show kiwitcms

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

Note: The pip show kiwitcms 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 Kiwitcms, 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

## Summary In Kiwi TCMS the fields `TestCase.extra_link` and `TestPlan.extra_link` were meant to represent URLs to external resources however in versions prior to 16.1 user input was not being sanitized and values were rendered verbatim which represents an opportunity for cross-site scripting exploitation. In version 16.1 these fields are properly sanitized and existing database records which don't validate will be reset to a null value. ## Impact Deployments which use the official Docker images and/or unmodified Kiwi TCMS middleware send a `Content-Security-Policy` header which makes this vulnerability difficult to exploit in practice because this header blocks the browser from executing inline JavaScript. Customized deployments which modify the default security settings may still be vulnerable.
