## Overview

An integer overflow in the query planning component of MongoDB Server can allow an authenticated user with ordinary database-level read/write privileges to bypass an internal resource limit. Submitting a specially crafted query causes the server to consume memory without bound during query planning, and the resulting exhaustion terminates the server process. This may result in a denial of service affecting all databases served by the affected node.

## Affected

- `mongodb >= 7.0.0, < 7.0.41`
- `mongodb >= 8.0.0, < 8.0.30`
- `mongodb >= 8.2.0, < 8.2.13`
- `mongodb >= 8.3.0, < 8.3.9`
- `mongodb = 9.0.0`

## Remediation

Upgrade past the affected range:

- `mongodb 8.3.9`
