## Overview

Improper handling of case sensitivity in the configuration validation component of MongoDB Server may cause the authorization subsystem to remain in a default disabled state during server startup. An unauthenticated user with network access to a deployment where this condition occurs can perform arbitrary administrative operations, resulting in full impact of data confidentiality, integrity, and availability.

## Affected

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

## Remediation

Upgrade past the affected range:

- `mongodb 8.3.9`
