CVE-2026-55630

What it is

Kiwi TCMS is an open source test management system. Prior to 16.1, TestCase.extra_link and TestPlan.extra_link accepted unsanitized user input and rendered stored values verbatim, creating an opportunity for cross-site scripting. Official Docker images and unmodified Kiwi TCMS middleware send a Content-Security-Policy header that blocks inline JavaScript, making exploitation difficult in default deployments, while customized deployments that weaken those security settings may remain vulnerable. Version 16.1 properly sanitizes both fields and resets existing database records that do not validate to null. This issue is fixed in version 16.1.
