How to fix?

Upgrade loopback to version 2.40.0, 3.22.0 or higher.

Overview

loopback is a highly-extensible, open-source Node.js framework that enables you to create dynamic end-to-end REST APIs, access data from several databases, incorporate model relationships and access controls for complex APIs, and more.

Affected versions of this package are vulnerable to Improper Authorization. An attacker can create Authentication Tokens on behalf of other users. If the AccessToken model is publicly exposed, the attacker can create tokens for any user as long as they know the target's userId. This will allow the attacker to access the user's data and their privileges.
