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 · moderate confidenceJetBrains YouTrack before version 2026.2.16593 contains an improper authorization vulnerability in the app configurations endpoint. The endpoint failed to properly validate user permissions before allowing modifications to project settings, potentially enabling authenticated users to alter configurations beyond their authorized scope.

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 YouTrack versionNavigate to YouTrack administration settings or check the version displayed in the application footer. Alternatively, access the /api/admin/version endpoint if API access is available.Affected if The installed version is lower than 2026.2.16593 (for example, 2026.2.16500 or any earlier release).
-
Identify app configurations endpoint accessReview the YouTrack API documentation or examine available REST API endpoints, specifically looking for project configuration or application settings endpoints under the admin or project management paths.Affected if The endpoint exists in the deployment and is accessible to authenticated users without elevated admin privileges.
-
Verify user permission enforcementUsing a standard authenticated user account (non-admin), attempt a request to modify project settings via the app configurations endpoint. Observe whether the request succeeds despite the user lacking the required project admin permissions.Affected if Users with limited permissions can successfully modify configurations that should require elevated privileges.
You are affected if your YouTrack version is below 2026.2.16593 and the app configurations endpoint permits unauthorized modifications by low-privilege authenticated users.

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 · scoped2026.2.16593
Upgrade YouTrack to version 2026.2.16593 or later to remediate the improper authorization vulnerability in the app configurations endpoint.
2026.2.16593
- 1. Back up your YouTrack database and configuration files before upgrading
- 2. Download YouTrack version 2026.2.16593 or later from the official JetBrains website (www.jetbrains.com/youtrack)
- 3. Stop the YouTrack service
- 4. Install the new version following JetBrains standard upgrade procedures
- 5. Start the YouTrack service
- 6. Verify the upgrade was successful by checking the version in YouTrack settings and testing that project settings modifications require proper authorization
