Only users with the unfiltered_html role will be allowed to insert unfiltered HTML. This includes PHP code, so users without admin or editor permissions will not be able to use this to execute code, even if they have widget editing permissions.

While this plugin works and is simple to use, the code needs to be updated (bug fixes, improvements). For instance, this issue is 9 months old: https://wordpress.org/support/topic/javascript-bug-2?replies=1.
