I can confirm that bug since the upgrade to 18.10. Sometimes also the field to enter the password is missing on the lock screen (see attached picture).

I tried clicking on items on the bar and it launched those applications. If someone had a privileged script or app pinned to their task bar, it appears that anyone could launch it. The window isn't visible however.
