Miggo AIRoot Cause Analysis

The vulnerability stemmed from missing project isolation in share network database queries. The commit diff shows the critical addition of 'project_only=True' to the model_query in _network_get_query. This parameter enforces tenant isolation in OpenStack's policy framework. Prior to the fix, the absence of this check allowed context-free UUID lookups across projects. The tests (test_api.py) were also modified to use elevated contexts for cross-project operations, confirming the default API behavior lacked proper scoping.
