Give assistive access to a single applescript I have this script:

#!/usr/bin/env osascript
activate application "SystemUIServer"
tell application "System Events"
tell process "SystemUIServer" to keystroke "q" using {command down, control down}
end tell


It needs assistive access. It seems I have to enable this access for the whole terminal application (iTerm2 in my case) to get it to work. This seems like giving a lot of privilege to iTerm. What are the security implications? Is there a workaround?
"Is there a workaround?"  I'd call it the "right" way.

Use the script editor. save the script as an application.  Thus, the script becomes a full fledged  application.  Give the app assertive capabilities.   should you want to start the app from the terminal, open your-app.
