Description

Kiwi TCMS vulnerable to stored XSS via JavaScript: URI in extra_link field (TestPlan & TestCase)

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability none.

Weakness class

CVE-2026-55630 is classified as CWE-79: Cross-site Scripting (XSS). User-supplied data is written into a page without escaping, so attacker script runs in the browser of anyone who views it.
