Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed TeamCity version
    Log into the TeamCity web interface as an administrator, then navigate to the 'Administration' > 'Server Administration' > 'Server Information' page. The version number is displayed there.
    Affected if The displayed version is any version number lower than 2025.11 (for example, 2025.10, 2024.2, etc.)
  2. Confirm VCS Root feature is accessible
    In the TeamCity web interface, navigate to 'Project Settings' > 'VCS Roots'. This feature is a core component of TeamCity and is typically available in all installations.
    Affected if The VCS Root configuration page loads successfully, indicating the vulnerable feature is present in the environment
  3. Verify web interface is reachable
    Attempt to access the TeamCity web console URL (typically on port 80 or 443). The reflected XSS is triggered through crafted URLs to the VCS Root setup endpoint.
    Affected if The TeamCity web interface is accessible over HTTP/HTTPS, as this is required for the URL-based reflected XSS attack vector

If your TeamCity server version is below 2025.11 and the web interface is accessible, you are affected by this reflected XSS vulnerability in the VCS Root setup feature.
