Which devices to check

Inventory Edge for Android and flag builds below 157.0.4341.53 for update. Microsoft identifies the fixed build and gives no complete affected-version matrix. Desktop Edge, Edge for iOS, and WebView2 require separate CVE-specific confirmation. No Edge-specific workaround or vendor-directed compromise checks or credential rotation were verified.

What to do across customers

  1. Inventory the installed Edge app and version across managed Android devices and work profiles. Start with devices used for privileged Microsoft 365, Entra, Intune or RMM access.
  2. If compromise is suspected, follow the customer’s incident response process. Isolate the device where supported, preserve evidence, and review associated endpoint and privileged sign-in activity.
  3. Roll out the updated app through Managed Google Play for Intune-managed Android Enterprise devices, or the applicable Google Play channel. Relaunch Edge and verify the installed build in the relevant profile. Track devices below the fixed build or missing from inventory until verified.
