Root Cause Analysis
The advisory explicitly states the vulnerability stems from unescaped job descriptions in column tooltips. In Jenkins plugin architecture:
- Column rendering typically involves Java classes extending Column
- Tooltip content generation would likely be handled by a method like getTooltip()
- The lack of escaping suggests missing Util.escape() or equivalent output encoding
- High confidence comes from the direct match between described vulnerability pattern (unfiltered job description in UI element) and common Jenkins plugin implementation patterns, even without seeing the exact code.
