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.
-
Identify installed YouTrack versionCheck the YouTrack version running in your environment. This is typically visible in the YouTrack administration UI under 'About' or can be retrieved via the /api/version endpoint if accessible to administrators.Affected if The installed version is lower than 2026.1.13570.
-
Confirm Planning Canvas feature is enabledVerify whether the Planning Canvas feature is currently active in your YouTrack instance. This can be checked in the YouTrack administration settings under project or plugin configuration.Affected if Planning Canvas is enabled and accessible to users in your environment.
-
Review user role assignments for Planning CanvasExamine which users or groups have been granted access to the Planning Canvas feature. Check role-based access control (RBAC) settings in YouTrack administration under users, groups, and roles.Affected if Users beyond your trusted administrators or security team have Planning Canvas access.
-
Inspect for unauthorized issue access patternsReview access logs or audit trails for the Planning Canvas endpoint to identify if any authenticated users have accessed issues or articles outside their assigned permissions.Affected if Audit logs show users accessing restricted content through Planning Canvas that they should not have permission to view.
-
Check for vulnerable configuration stateDetermine if the YouTrack instance is configured in a way that allows authenticated users to interact with the Planning Canvas feature without proper permission validation.Affected if The Planning Canvas feature is accessible to authenticated users without additional access control restrictions beyond standard YouTrack permissions.
Your environment is affected if YouTrack version is below 2026.1.13570 and the Planning Canvas feature is enabled for users in your instance.
