CVE-2025-21187

The fix

Microsoft fixes this in a Microsoft Store app update, so Windows Update and WSUS won't deliver it. The app at the version below, or later, has the fix.

The Store updates these apps on its own schedule. A machine with Store updates turned off, or no Store access at all (common on managed fleets), keeps the old version. To check one, run Get-AppxPackage -AllUsers -Name Microsoft.PowerAutomateDesktop and compare its Version to the table. A version below 2.0 is the small placeholder Windows installs in the app's place, not the app itself, so it isn't affected.
