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.
