  "details": "RT's automatic link creation for URLs in HTML ticket content does       not HTML-escape the URL it places in the link. A URL crafted to       break out of the link's address can add a script that runs when the       ticket history is displayed, with no further action by the viewer.       Anyone who can add HTML content to a ticket can plant it. That       includes an unauthenticated sender of HTML email to any queue that       grants CreateTicket or ReplyToTicket to Everyone, which is routine       for a queue that accepts mail from the public. The script runs in       the session of any user who views the ticket, and can act in RT       with that user's authority.   This issue was fixed in version 5.0.11 and 6.0.4",
