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 Windows version numberOpen Settings > System > About, or run 'winver' in Run dialog, or run 'systeminfo' in Command Prompt and look at the 'OS Version' lineAffected if The version is 10.0.26100.x where x is less than 6899, or 10.0.26200.x where x is less than 6899, or the system is Windows Server 2025 with version below 10.0.26100.6899
-
Confirm PrintWorkflowUserSvc service existsOpen Services snap-in (services.msc) and look for 'PrintWorkflowUserSvc', or run 'sc query PrintWorkflowUserSvc' in Command PromptAffected if The service exists on the system (this is the vulnerable component)
-
Check for installed security updatesOpen Settings > Windows Update > Update history, or run 'wmic qfe list' in Command Prompt, and look for the security update corresponding to CVE-2025-55684Affected if The specific KB patch for this CVE is NOT installed or the installation date is before the patch release date
A system is affected if it runs a Windows 11 24h2, 25h2, or Windows Server 2025 version below the threshold AND has the PrintWorkflowUserSvc service present AND lacks the corresponding security update.
