How to fix?

Upgrade Minimos:latest mongo-8.2 to version 8.2.9-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mongo-8.2 package and not the mongo-8.2 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

After invoking $_internalJsEmit, which is not intended to be directly accessible, or mapreduce command’s map function in a certain way, an authenticated user can subsequently crash mongod when the server-side JavaScript engine (through $where, $function, mapreduce reduce stage, etc.) is used also in a specific way, resulting in a post-authentication denial-of-service.

This issue impacts MongoDB Server v8.2 versions prior to 8.2.9 and v8.3 versions prior to 8.3.2.
