How to fix?

Upgrade org.apache.nifi:nifi-nar-bundles to version 1.10.0 or higher.


org.apache.nifi:nifi-nar-bundles is a system to process and distribute data.

Affected versions of this package are vulnerable to Session Fixation. When using an authentication mechanism other than PKI, when the user clicks Log Out, NiFi invalidates the authentication token on the client side but not on the server side. This permits the user's client-side token to be used for up to 12 hours after logging out to make API requests to NiFi.
