["Akhil Naik (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-25384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16941546#comment-16941546 ] 

Akhil Naik commented on AMBARI-25384:
-------------------------------------

The Root Cause of this issue is, when ever we do a call to : this.get('logger') and then write danger or warn messages to alert it in UI, it was executed in DOM with direct message we passed to it , which need to be HTML safe .


Added the escapeExpression call in the places where we where sending direct data to DOM .
