Miggo AIRoot Cause Analysis

The vulnerability involves bypassing ACL checks when accessing blocks by ID. The primary suspects are functions handling block retrieval requests. BlockEndpoint.handleGetBlock would be the REST API entry point for block operations, and OzoneManager.getBlockDetails would be the core metadata lookup. Both would require authorization checks added in 1.2.0. Confidence is medium due to lack of direct patch access, but alignment with Ozone architecture and vulnerability patterns.
