Summary
Kiwi TCMS, a test management system, had vulnerabilities in file upload validation, allowing potentially dangerous files to be uploaded and arbitrary JavaScript execution in the browser. Additionally, Nginx's `proxy_pass` directive could strip some headers, weakening the protections of Kiwi TCMS when served behind a reverse proxy.
Risk Assessment
Organizations may be exposed to XSS attacks and other risks associated with uploading dangerous files, potentially leading to data theft or system compromise.
Recommendation
It is recommended to upgrade to version 12.4 of Kiwi TCMS. Users unable to upgrade should ensure that additional header values are still passed to the client browser in the proxy configuration.
Other vulnerabilities in Kiwi TCMS
See all- CVE-2026-55630Unknown
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.
- CVE-2026-54724Medium
In Kiwi TCMS prior to 16.1, the account confirmation endpoint accepted an unvalidated next parameter, allowing an unauthenticated attacker to create a URL on a trusted Kiwi TCMS hostname that redirects a victim to an arbitrary external domain. The trusted origin can support credential-harvesting pages, bypass email security filters and link-reputation checks, or deliver malware through a convincing account-confirmation lure. This issue is fixed in version 16.1.
- CVE-2023-36809High
Kiwi TCMS, a test management system, had an issue with incorrect Nginx configuration that allowed potentially dangerous scripts to be executed from attachments. Versions prior to 12.5 improperly handled the `Content-Type: text/plain` header, posing a risk to users.
Original NVD description (English source)
Kiwi TCMS is an open source test management system for both manual and automated testing. Kiwi TCMS allows users to upload attachments to test plans, test cases, etc. Earlier versions of Kiwi TCMS had introduced upload validators in order to prevent potentially dangerous files from being uploaded and Content-Security-Policy definition to prevent cross-site-scripting attacks. The upload validation checks were not 100% robust which left the possibility to circumvent them and upload a potentially dangerous file which allows execution of arbitrary JavaScript in the browser. Additionally we've discovered that Nginx's `proxy_pass` directive will strip some headers negating protections built into Kiwi TCMS when served behind a reverse proxy. This issue has been addressed in version 12.4. Users are advised to upgrade. Users unable to upgrade who are serving Kiwi TCMS behind a reverse proxy should make sure that additional header values are still passed to the client browser. If they aren't redefining them inside the proxy configuration.
