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. Verify the PrintWorkflowUserSvc service exists
    Open Services (services.msc) and locate 'PrintWorkflowUserSvc' or run: Get-Service -Name PrintWorkflowUserSvc
    Affected if The service is present on the system. Note: This service is optional and may not be present on all systems.
  2. Check the installed Windows version
    Run 'winver' or 'systeminfo | findstr /B /C:"OS"' to obtain the full version number, then compare it against the affected version ranges provided in the CVE
    Affected if The installed version is lower than any of these thresholds: Windows 10 1809 < 10.0.17763.6659, 21h2 < 10.0.19044.5247, 22h2 < 10.0.19045.5247; Windows 11 22h2 < 10.0.22621.4602, 23h2 < 10.0.22631.4602, 24h2 < 10.0.26100.2605; Server 2019 < 10.0.17763.6659; Server 2022 < 10.0.20348.2966
  3. Confirm the security update is installed
    Run 'Get-HotFix -ID KB5055523' or check Windows Update history for KB5055523
    Affected if The update KB5055523 is NOT installed on the system

A system is affected if it runs a Windows version within the affected ranges AND has the PrintWorkflowUserSvc service present AND does not have KB5055523 installed.
