Miggo AIRoot Cause Analysis

The vulnerability stems from missing permission checks in the Friendly URL module's history retrieval functionality. Analysis focused on:

  1. Core data access methods in the service layer that would return historical URL entries
  2. Web layer entry points that handle user requests for URL history While no patch code is available, Liferay's architecture patterns suggest these components would require permission checks (likely added via PermissionChecker.hasPermission() calls in fixed versions). The medium confidence reflects educated inference based on vulnerability patterns in Liferay's permission system and module structure.
