Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

In JetBrains TeamCity before 2023.11.2 stored XSS via agent distribution was possible

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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. Check TeamCity server version
    Navigate to Administration > About in the TeamCity web UI, or check the version string in the server logs or startup output
    Affected if The displayed version is earlier than 2023.11.2
  2. Verify agent distribution feature usage
    Check if any agent pools or agent configurations exist in the TeamCity interface under Administration > Agent Pools
    Affected if Agent pools or agent configurations are present and the TeamCity version is below 2023.11.2
  3. Review recent agent distribution settings
    Inspect any recently created or modified agent configurations, particularly any custom parameters or labels assigned to build agents
    Affected if Custom agent parameters exist and the TeamCity version is below 2023.11.2
  4. Audit user interactions with agent distribution
    Review server access logs for requests to agent-related endpoints, looking for suspicious script tags or unusual parameter patterns in distribution-related URLs
    Affected if Suspicious patterns are found in logs and the TeamCity version is below 2023.11.2

You are affected if your TeamCity installation version is earlier than 2023.11.2 and the agent distribution feature is in use.
