Miggo AIRoot Cause Analysis

The vulnerability manifests in user management functionality where: 1) Input handlers accept unsanitized HTML in nickname fields (stored persistence) 2) Output rendering displays the unsanitized stored data. While exact code isn't available, the pattern matches common XSS vulnerabilities in MVC frameworks where user input isn't properly filtered before storage and output. The medium confidence comes from matching the vulnerability pattern to typical framework architecture rather than direct code analysis.
