Technical details
The $_internalListQuerySettings operation in MongoDB's aggregation framework lacks required authorization checks for the querySettings privilege, allowing privilege escalation. An authenticated user with arbitrary (including minimal) credentials can bypass authorization controls to access deployment-wide query configuration. This is an authorization bypass in the aggregation framework component; remediation exists in version 9.0.7.
