## Overview

Improper neutralization of special elements in data query logic in the polymorphic relation handling of the MongoDB integration for Laravel can cause a caller-supplied relation identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence a stored relation identifier may cause an affected application to return a document other than the intended relation target.

## Affected

- `laravel_mongodb >= 1.2.0, < 5.11.0`

## Remediation

Upgrade past the affected range:

- `laravel_mongodb 5.11.0`
