CVE-2023-44981 describes an Authorization Bypass Through User-Controlled Key vulnerability in Apache ZooKeeper, affecting versions prior to 3.9.1, 3.8.3, and 3.7.2. This critical flaw (CVSS 9.1) allows an unauthenticated attacker to join a ZooKeeper cluster and propagate counterfeit changes, gaining complete read-write access to the data tree, provided SASL Quorum Peer authentication is enabled and the instance part of the SASL ID is missing. While not actively exploited in the wild (KEV: No), its high severity and ease of exploitation (AV:N/AC:L/PR:N/UI:N) warrant immediate attention. Community discussion indicates awareness, though no public exploit code or media coverage has been identified.
