Miggo AIRoot Cause Analysis

The vulnerability stems from unescaped view names in the view selection dropdown. Jenkins plugins typically use Jelly templates for UI rendering. The core issue would be in the template that generates the dropdown options, likely using ${view.name} without the escape attribute or equivalent output sanitization. The high confidence comes from: 1) The advisory explicitly mentions the dropdown as the vulnerable component 2) XSS patterns in Jenkins typically involve missing Jelly escaping 3) The plugin's purpose (view tabbar) matches this UI element's functionality.
