How to fix?

Upgrade org.apache.zookeeper:zookeeper to version 3.4.10, 3.5.4-beta or higher.

Overview

org.apache.zookeeper:zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.

Affected versions of this package are vulnerable to Authentication Bypass. No authentication/authorization is enforced when a server attempts to join a quorum, as a result an arbitrary end point could join the cluster and begin propagating counterfeit changes to the leader.
