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 2022.04.7, 2022.10.6, 2023.05.6, 2023.11.5 reflected XSS via OAuth provider configuration 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.

dbcve analysis · high confidence

Reflected XSS vulnerability in TeamCity's OAuth provider configuration allows attackers to inject malicious scripts through OAuth settings pages. User-supplied input in the OAuth provider configuration is not properly sanitized, enabling script execution in the context of the victim's browser.

MitigationUpgrade TeamCity to version 2022.04.7, 2022.10.6, 2023.05.6, 2023.11.5 or later to obtain the security fix. Validate that OAuth authentication continues to function correctly after the upgrade.

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 TeamCity server version
    Log into TeamCity as administrator, navigate to Administration > Server Administration > Server Information page, or check the version.txt file in the <TeamCity data directory>/config directory
    Affected if The displayed version number falls into any of these ranges: < 2022.04.7, >= 2022.10 but < 2022.10.6, >= 2023.05 but < 2023.05.6, or >= 2023.11 but < 2023.11.5
  2. Verify OAuth provider is configured
    Navigate to Administration > Authentication > OAuth Providers (or Authentication Settings) in the TeamCity web interface to see if any OAuth providers are enabled and configured
    Affected if One or more OAuth providers (such as GitHub, Google, GitLab, or custom OAuth2) are added and enabled on the server
  3. Confirm XSS payload delivery vector exists
    Examine the OAuth provider settings pages by accessing the configuration form for each enabled OAuth provider; the vulnerability exists in the input fields where OAuth client ID, client secret, or custom parameters are stored
    Affected if The TeamCity version is affected AND the OAuth provider configuration page accepts and saves user-supplied values without visible sanitization or encoding in the response

You are affected if your TeamCity server version is less than 2022.04.7, between 2022.10-2022.10.5, between 2023.05-2023.05.5, or between 2023.11-2023.11.4, AND you have OAuth providers configured on your server.

Interim mitigation

Upgrade TeamCity to version 2022.04.7, 2022.10.6, 2023.05.6, 2023.11.5 or later to obtain the security fix. Validate that OAuth authentication continues to function correctly after the upgrade.

Recommended fix High confidence

2023.11.5 (or latest stable 2023.11.x release)

  1. 1. Identify current TeamCity version by navigating to Administration > Global Settings
  2. 2. Based on current version, determine target upgrade version: if < 2022.04, upgrade to 2022.04.7 or later; if >= 2022.10 and < 2022.10.6, upgrade to 2022.10.6; if >= 2023.05 and < 2023.05.6, upgrade to 2023.05.6; if >= 2023.11 and < 2023.11.5, upgrade to 2023.11.5
  3. 3. Back up the TeamCity database and configuration files before upgrading
  4. 4. Download the target fixed version from www.jetbrains.com/teamcity/download/
  5. 5. Stop the TeamCity server
  6. 6. Install the upgrade following standard TeamCity upgrade documentation
  7. 7. Start the TeamCity server and verify all services are running
  8. 8. Verify the OAuth provider configuration page is accessible and functions correctly
