CVE intelligence and bounded remediation

CVE-2023-27489 — Kiwi TCMS is an open source test management system for both manual and automated testing

High CVSS 7.6

Kiwi TCMS is an open source test management system for both manual and automated testing. Kiwi TCMS accepts SVG files uploaded by users which could potentially contain JavaScript code. If SVG images are viewed directly, i.e. not rendered in an HTML page, this JavaScript code could execute. This vulnerability has been fixed by configuring Kiwi TCMS to serve with the Content-Security-Policy HTTP header which blocks inline JavaScript in all modern browsers. This configuration change is provided in version 12.1 and users are advised to upgrade. Users unable to upgrade may set their Content-Security-Policy HTTP header manually.

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
