Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache ZooKeeper versions before 3.7.2, from 3.8.0 before 3.8.3, and from 3.9.0 before 3.9.1 are affected when SASL Quorum Peer authentication is enabled (quorum.auth.enableSasl=true). A party that can reach the ensemble's quorum communication can join the cluster without the instance check by using an authentication ID with no instance part, then send counterfeit changes to the leader and gain full read-write access to the data tree. Upgrade to 3.7.2, 3.8.3, or 3.9.1. Until then, protect the election and quorum traffic with a firewall.
