HIGHCVE-2023-30613 is a high-severity (CVSS 8.1) Unrestricted File Upload vulnerability in kiwitcms. O3 Security confirms whether CVE-2023-30613 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Kiwi TCMS unrestricted file upload vulnerability
Blast Radius
kiwitcmsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Kiwi TCMS, an open source test management system, allows users to upload attachments to test plans, test cases, etc. In versions of Kiwi TCMS prior to 12.2, there is no control over what kinds of files can be uploaded. Thus, a malicious actor may upload an .exe file or a file containing embedded JavaScript and trick others into clicking on these files, causing vulnerable browsers to execute malicious code on another computer.
Kiwi TCMS v12.2 comes with functionality that allows administrators to configure additional upload validator functions which give them more control over what file types are accepted for upload. By default .exe are denied. Other files containing the <script> tag, regardless of their type are also denied b/c they are a path to XSS attacks. There are no known workarounds aside from upgrading.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for kiwitcms. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update kiwitcms to 12.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-30613 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2023-30613 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-30613. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
