Hi, The following vulnerability was published for zookeeper. CVE-2023-44981[0]: | Authorization Bypass Through User-Controlled Key vulnerability in | Apache ZooKeeper. If SASL Quorum Peer authentication is enabled in | ZooKeeper (quorum.auth.enableSasl=true), the authorization is done | by verifying that the instance part in SASL authentication ID is | listed in zoo.cfg server list. The instance part in SASL auth ID is | optional and if it's missing, like 'e...@example.com', the | authorization check will be skipped. As a result an arbitrary | endpoint could join the cluster and begin propagating counterfeit | changes to the leader, essentially giving it complete read-write | access to the data tree. Quorum Peer authentication is not enabled | by default. Users are recommended to upgrade to version 3.9.1, | 3.8.3, 3.7.2, which fixes the issue. Alternately ensure the | ensemble election/quorum communication is protected by a firewall as | this will mitigate the issue. See the documentation for more | details on correct cluster administration. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
