Versions before and including 2.27.0 use a block list of specific keys that should be sanitized from the request object contained in the error object. When a request to Auth0 management API fails, the key for Authorization header is not sanitized and the Authorization header value can be logged exposing a bearer token.

You are affected by this vulnerability if all of the following conditions apply:

• You are using auth0 npm package.

• You are using a Machine to Machine application authorized to use Auth0's management API Client Credentials Flow.

Upgrade to version 2.27.1.

The fix provided in patch will not affect your users.
