1) You need permissions to publish a post from the public interface:

The submission form is not well sanitized and will result in stored xss
in admin pages:

* Name field is not sanitized and it's injectable with a payload
which will be stored in the pending submission page in admin panel
POC: myname'"><script>window.alert(document.cookie)</script>

* Email field is not sanitized but can it will check for a valid email address
so the maximum result will be a reflected xss
POC: [email protected]'"><script>window.alert(document.cookie)</script>

* Post Title is not sanitized and it's injectable with a payload
which will be stored in the pending submissions page in admin panel
POC: title'"><script>window.alert(document.cookie)</script>
