Information disclosure through error object in auth0.js

Description

Between versions 8.0.0 and 9.13.1(inclusive), 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.

Recommendation

Update the auth0-js package to the latest compatible version. Followings are version details:

• Affected version(s): >= 8.0.0, < 9.13.2
• Patched version(s): 9.13.2
