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 YouTrack before 2019.2.55152, removing tags from the issues list without the corresponding permission 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 · moderate confidence

This is an authorization bypass vulnerability in YouTrack where users could remove tags from issues without having the required permission to do so. The vulnerability exists due to missing or insufficient permission checks on tag removal operations.

MitigationUpgrade YouTrack to version 2019.2.55152 or later which contains the vendor fix. Verify that proper permission enforcement is in place for tag management operations.

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 YouTrack version
    Access the YouTrack administration interface and navigate to the 'About' or 'System Info' section to find the installed version number
    Affected if The installed version is lower than 2019.2.55152
  2. Check YouTrack version via API
    Use the YouTrack REST API endpoint '/api/serverInformation' or check the build number in the installation directory if you have direct server access
    Affected if The version/build returned is earlier than 2019.2.55152
  3. Verify tag removal permission enforcement
    Create a test user without tag management permissions and attempt to remove a tag from an issue they do not own
    Affected if The user is able to successfully remove tags without the required permissions
  4. Review audit logs for unauthorized tag operations
    Access YouTrack audit logs or activity log and search for tag removal events performed by users without tag management roles
    Affected if Tag removal operations are recorded from users lacking the 'Manage tags' permission

You are affected if your YouTrack version is below 2019.2.55152 AND users without tag management permissions can successfully remove tags from issues.
