Microsoft Edge (Chromium-based) has an incorrect authorization check that lets an already-authorized local user elevate their privileges. An attacker who already has a local account can gain higher rights on the machine.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Edge version by opening `edge://settings/help` or running `microsoft-edge --version` on Linux
