CVE-2024-54155
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 · uneditedIn JetBrains YouTrack before 2024.3.51866 improper access control allowed listing of project names during app import without authentication
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 confidenceThis is an improper access control vulnerability in JetBrains YouTrack's app import functionality. The flaw allows unauthenticated users to enumerate/list project names through the app import feature, exposing sensitive project information without requiring any authentication credentials.

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.
-
Check installed YouTrack versionAccess the YouTrack administration interface or check the version file in the YouTrack installation directory. On the main YouTrack page, the version is typically displayed in the footer or in Administration > System > Overview.Affected if The installed version is less than 2024.3.51866 (e.g., 2024.3.x versions before 51866, or any earlier version).
-
Verify app import endpoint accessibilityAttempt to access the app import API endpoint without authentication. This is typically found at a path like '/api/appImport/' or similar import-related endpoints. Use a browser or HTTP client to send a request without providing any login credentials.Affected if The endpoint returns a successful response (HTTP 200) with project data or project listing information instead of redirecting to a login page or returning an authentication error (HTTP 401/403).
-
Test project enumeration without authenticationSend an HTTP GET request to the app import feature's project listing endpoint without including any session cookies, authentication headers, or credentials. Observe whether the response contains project names or project identifiers.Affected if The response includes any project names, project IDs, or project metadata without requiring authentication.
You are affected if your YouTrack version is below 2024.3.51866 AND the app import endpoint is accessible without authentication, allowing unauthenticated project enumeration.

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 · scoped2024.3.51866
Upgrade YouTrack to version 2024.3.51866 or later, which implements proper authentication requirements for the app import feature. Verify after upgrade that project enumeration is no longer possible without authentication.
YouTrack 2024.3.51866 or later (2024.3.x stable release)
- 1. Back up your YouTrack installation and database before upgrading
- 2. Download YouTrack version 2024.3.51866 or later from the official JetBrains website (www.jetbrains.com/youtrack)
- 3. Stop the YouTrack service
- 4. Install the new version following JetBrains upgrade documentation
- 5. Start the YouTrack service
- 6. Verify that the improper access control vulnerability is fixed by confirming project names cannot be listed during app import without authentication
