There is a serious security problem in all etherpad versions. It
enables HTML injection into the time-slider. This allows an attacker
to execute arbitrary JavaScript on your domain.

Please fix this bug as soon as possible!

To fix the problem tou need to change a single line in
'etherpad/src/static/js/broadcast_slider.js'. You can even do this
live, without restarting etherpad.

Change
   nametd.html(author.name

|| "unnamed");
into
   nametd.text(author.name

|| "unnamed");
 around line 141 in the file.

You can see the needed change as a patch here ->

Kind Regards
