Electron: AppleScript injection in app.moveToApplicationsFolder on macOS

Impact

On macOS, app.moveToApplicationsFolder() used an AppleScript fallback path that did not properly handle certain characters in the application bundle path. Under specific conditions, a crafted launch path could lead to arbitrary AppleScript execution when the user accepted the move-to-Applications prompt.

Apps are only affected if they call app.moveToApplicationsFolder(). Apps that do not use this API are not affected.

Workarounds

There are no app side workarounds, developers must update to a patched version of Electron.

Fixed Versions

• 41.0.0-beta.8
• 40.8.0
• 39.8.1
• 38.8.6
