MongoDB Server: resource exhaustion
Fix: upgrade to 8.2.12 or later (2 fixed versions below)
An authenticated user can cause the mongod process to be terminated by the operating system under memory pressure via the $rankFusion and $scoreFusion aggregation stages. The issue originates in the server's error-handling path and requires the ability to run aggregation queries.
