auth0.js (NPM package auth0-js) greater than version 8.0.0 and before version 9.12.3 has a vulnerability. In the case of an (authentication) error, the error object returned by the library contains the original request of the user, which may include the plaintext password the user entered. If the error object is exposed or logged without modification, the application risks password exposure. This is fixed in version 9.12.3

In auth0 (npm package) versions before 2.27.1, a DenyList of specific keys that should be sanitized from the request object contained in the error object is used. The key for Authorization header is not sanitized and in certain cases the Authorization header value can be logged exposing a bearer token. You are affected by this vulnerability if you are using the auth0 npm package, and you are using a Machine to Machine application authorized to use Auth0's management API
