Root Cause Analysis
The vulnerability stems from unescaped output of user-controlled data (filenames) in HTML contexts. Jenkins plugins typically use Jelly templates for UI rendering, and the advisory specifically mentions tooltip XSS. The core issue would be in the template that displays locked files, where ${...} output (without escaping) is used instead of ${%...%} or explicit escaping methods. While exact line numbers aren't provided, the pattern matches Jenkins XSS vulnerabilities where dynamic content isn't properly sanitized in view templates.
