This vulnerability allows attackers to forge tokens and bypass authentication and authorization mechanisms.

Am I affected?

You are affected by this vulnerability if you use a Passport-SharePoint version earlier than 0.4.0.

How do I fix this?

Developers using the Passport-SharePoint library must upgrade to version 0.4.0.

Please note that Auth0 has deprecated and will no longer maintain this library. Developers should plan to discontinue its use.
