Root Cause Analysis
The vulnerability stems from unescaped method information in tooltips. Jenkins plugins typically use Jelly templates for UI rendering and Java classes for data processing. The combination of:
- A Java method (ScatterPlotAction.generateTooltip) processing raw method data from reports without sanitization
- A Jelly template (index.jelly) directly rendering this unsanitized data into HTML tooltip attributes via ${...} expressions creates the XSS vector. The pattern matches Jenkins' common XSS vulnerability patterns where user-controlled data flows into UI elements without escaping.
