Miggo AIRoot Cause Analysis

The vulnerability stems from how Materialize's autocomplete component handles user input. Multiple sources (CVE description, GitHub issue #6286, and Snyk report) show the component injects unescaped content via:

  1. The renderItem method that creates suggestion elements using innerHTML
  2. The initialization logic that processes user-supplied data objects without sanitization

The GitHub PR #49 fix introduces textContent usage and an allowUnsafeHTML flag, confirming these were the injection points. The file path is inferred from standard Materialize directory structure and component organization.
