Miggo AIRoot Cause Analysis

The vulnerability centers on Document Level Security (DLS) bypass via improper authorization in query processing. Based on Elasticsearch's architecture:

  1. SecurityIndexSearcherWrapper is a core component for applying DLS filters during query execution. Flaws here could allow queries to skip security constraints.
  2. DLSRoleQueryValidator handles query validation for role-based access. Incorrect validation logic could permit unsafe query structures. The confidence is 'medium' because the exact patch details are unavailable, but these functions align with the described vulnerability mechanism and Elasticsearch's security implementation patterns.
