When sslQuorum=true, zookeeper.fips-mode=true, ssl.quorum.hostnameVerification=true, and ssl.quorum.clientHostnameVerification=true are enabled, the Java SSLSocket quorum path accepts a CA-trusted peer certificate whose SAN does not match the connected host. A malicious or misissued peer certificate can therefore join quorum traffic, participate in leader election, and enter replication flows.</p> <p>Users are recommended to upgrade to version 3.8.7 or 3.9.6, which fixes the issue.</p> <p><strong>Affected:</strong> Apache Software Foundation Apache ZooKeeper</p> <p>Apache ZooKeeper quorum TLS fails to enforce peer hostname verification in FIPS-mode deployments.
