Technical details
The aggregation framework fails to validate privileges for nested operations within view definitions, specifically in $graphLookup's $_internalFromPipeline field. An authenticated user with readWriteAnyDatabase role can craft a view that leaks collections they lack read access to by nesting unauthorized pipeline stages inside $_internalFromPipeline. The privilege evaluation gap allows these nested stages to execute without proper authorization checks.
