Miggo AIRoot Cause Analysis

The vulnerability description explicitly names django.views.defaults.page_not_found() as the source of improper input validation. Security patches modified this view to quote the request_path context variable and remove path display from the default template. The function's role in rendering error pages with unescaped user input directly matches the described content spoofing mechanism.
