Description

Electron: Unquoted executable path in app.setLoginItemSettings on Windows

Impact

On Windows, app.setLoginItemSettings({openAtLogin: true}) wrote the executable path to the Run registry key without quoting. If the app is installed to a path containing spaces, an attacker with write access to an ancestor directory may be able to cause a different executable to run at login instead of the intended app.

On a default Windows install, standard system directories are protected against writes by standard users, so exploitation typically requires a non-standard install location.

Workarounds

Install the application to a path without spaces, or to a location where all ancestor directories are protected against unauthorized writes.
