This vulnerability occurs in the MongoDB Query Planner where complex queries can cause excessive memory usage. This excessive memory consumption can lead to an Out-Of-Memory (OOM) crash, causing the database service to stop functioning properly.

Impact Analysis

The impact of this vulnerability is primarily availability-related. Because complex queries can cause the MongoDB Query Planner to consume excessive memory and crash, it can lead to denial of service where the database becomes unavailable until it is restarted or recovered.
