Root Cause Analysis
The vulnerability stems from unescaped output of it.location.description in Jelly template tooltip attributes. The commit diff shows the fix added h.xmlEscape() around these values. Since Jelly templates automatically HTML-escape ${} expressions but not attribute values, the tooltip attribute required explicit XML escaping. The vulnerable code paths are the template rendering mechanisms that display deployment location metadata without proper context-aware escaping.
