CVE-2026-26149
Critical CVSS 9Published 2026-04-14 ยท last changed 2026-10-26
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.
| App | Fixed in version | Package | Released |
|---|---|---|---|
| Microsoft Power Apps Desktop Client | 3.26032.10.0 | MicrosoftCorporationII.PowerAppsforWindows10 | 2026-11-08 |
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 MicrosoftCorporationII.PowerAppsforWindows10 and
compare its Version to the table.
What it is
Improper neutralization of escape, meta, or control sequences in Microsoft Power Apps allows an authorized attacker to perform spoofing over a network.
