## Overview

MongoDB Server contains an incorrect authorization vulnerability in the aggregation framework. An authenticated user with minimal privileges can craft a specially formatted aggregation request that causes the server's authorization subsystem to evaluate a different operation than what is actually executed, resulting in unauthorized read access to collection data within the target database.

## Affected

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

## Remediation

Upgrade past the affected range:

- `mongodb 8.0.30`
