## Overview

Mongoid does not restrict which query operators may come from caller-supplied filter data when an application hands that data to its query-building methods. In an application that forwards externally supplied filter parameters in this way, a party with no credentials may influence how the database evaluates the query. This may result in unintended disclosure of stored field values and in reduced database performance.

## Affected

- `mongoid >= 8.0.0, < 8.0.13`
- `mongoid >= 8.1.0, < 8.1.13`
- `mongoid >= 9.0.0, < 9.0.12`
- `mongoid = 9.1.0`

## Remediation

Upgrade past the affected range:

- `mongoid 9.0.12`
