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.

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 confidencePath traversal vulnerability in JetBrains TeamCity allows attackers to write files to arbitrary locations on the server during project archive upload operations, potentially enabling unauthorized file creation or overwrite on the host system.

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 checksWork through these to decide whether this CVE applies to you.
-
Determine installed TeamCity versionAccess the TeamCity web interface and navigate to the Administration > Server Administration > Server Information page, or append /about.html to your TeamCity URL to view version informationAffected if version displayed is lower than 2025.07.2
-
Verify project archive upload feature existsIn TeamCity web UI, navigate to the Project Settings or Administration area and look for project import/export or archive upload functionality (typically under Server Administration > Import/Export)Affected if archive upload or project import feature is present and accessible in the UI
You are affected if your TeamCity version is below 2025.07.2 and the project archive upload/import feature is available in your installation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2025.07.2
Upgrade TeamCity to version 2025.07.2 or later to remediate the path traversal vulnerability during project archive upload.
2025.07.2
- 1. Back up the TeamCity data directory (typically <TeamCity_home>/data) and database
- 2. Download TeamCity 2025.07.2 from the official JetBrains website (www.jetbrains.com/teamcity/download)
- 3. Stop the TeamCity server service
- 4. Install or extract the new TeamCity 2025.07.2 distribution
- 5. Start the TeamCity server and verify it is running correctly
- 6. Verify the path traversal vulnerability is resolved by testing project archive uploads
