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.

NVD · unedited
In JetBrains TeamCity before 2019.2.3, password parameters could be disclosed via build logs.

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.

dbcve analysis · high confidence

In JetBrains TeamCity versions prior to 2019.2.3, password-type parameters used in build configurations were being written in plain text to build logs. This exposed sensitive credentials to anyone with access to view those build logs.

MitigationUpgrade TeamCity to version 2019.2.3 or later, and audit existing build logs and configurations to identify and rotate any exposed credentials.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 version
    Access the TeamCity administration web interface and navigate to 'About' or check the version displayed on the login page. Alternatively, check the version from the server startup logs or the TeamCity installation directory.
    Affected if The installed version is any version prior to 2019.2.3 (e.g., 2019.2.2, 2019.2.1, 2019.2.0, earlier releases).
  2. Identify password-type parameters in build configurations
    Review all build configurations in the TeamCity web interface under 'Build Configurations' and inspect parameter definitions. Look for parameters with type 'password' or those explicitly marked as sensitive.
    Affected if Any build configuration contains password-type parameters that have been used in build steps.
  3. Examine build logs for plain text credentials
    Access the build logs for builds that used password-type parameters. Navigate to a specific build run, open the build log, and search for the parameter names or look for visible password strings in the log output.
    Affected if Build logs contain the actual password values in plain text rather than being masked or hidden.
  4. Audit build log visibility settings
    Check who has access to view build logs in TeamCity by examining project and build configuration permissions. Determine if unauthorized or unexpected users can access these logs.
    Affected if Build logs with exposed credentials are accessible to users beyond those who need to know the credentials.

You are affected if your TeamCity version is prior to 2019.2.3 AND you have build configurations using password-type parameters, as those passwords may have been written in plain text to build logs.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
