Miggo AIRoot Cause Analysis

The patch modifies a JSP template that renders user-controlled data (wikiUserName) in a meta tag. The change from single to double quotes suggests the username value wasn't properly escaped for HTML attributes. The vulnerability manifests in the UserNameTag handler that processes and outputs the username value. As JSP custom tags typically implement doStartTag()/doEndTag() methods for rendering, the UserNameTag's doStartTag() method would be responsible for outputting the unescaped username value to the response stream.
