CVE-2026-79993

The deleteContainer opcode 0x14/20 is processed without verifying the caller's ACL permissions, allowing any authenticated client to delete specific znodes in the data tree regardless of the ACL restrictions on the znode or its parent. This opcode is considered internal-only and the official clie...

CVE-2026-84501

An unauthenticated attacker can inject arbitrary fake log lines into Apache ZooKeeper's operational log by sending a crafted addauth"ensemble", ... request containing newline characters \n. When the ensemble name doesn't match, EnsembleAuthenticationProvider.handleAuthentication logs the raw,...

CVE-2026-84439

When audit logging is enabled zookeeper.audit.enable=true, an unauthenticated attacker can inject arbitrary fields into Apache ZooKeeper's audit log by sending a digest authentication request with tab characters \t embedded in the username. Because the audit log uses tab-separated key=value forma...

CVE-2026-59739

Information disclosure via SetWatches reconnect replay in Apache ZooKeeper due to missing ACL check. An attacker can discover ACL-restricted paths by registering exists-watches on non-existent paths, then reconnecting after the paths are created with restricted ACLs. Issue is caused by incomplete...
