Overview
Affected versions of this package are vulnerable to Incorrect Authorization in the handleTokenExchange() function. An attacker can gain unauthorized access to restricted resources by exploiting the lack of enforcement of allowed connectors when exchanging tokens. This is only exploitable if an attacker obtains a valid client secret for a client that is configured to restrict allowed connectors and also possesses a valid identity token from a connector that should not be permitted.
