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...

CVE-2026-59969

Apache ZooKeeper quorum TLS fails to enforce peer hostname verification in FIPS-mode deployments. 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 pe...

CVE-2026-84439

Apache ZooKeeper is affected by an audit log injection vulnerability in zookeeper_audit.log. When audit logging is enabled (zookeeper.audit.enable=true), two attack vectors exist: an unauthenticated attacker can embed tab characters (\t) in a digest authentication username, and an authenticated c...

CVE-2026-79993

Apache ZooKeeper versions 3.9.0–3.9.5 and 3.8.0–3.8.6 are affected by an authorization bypass in the deleteContainer opcode (0x14/20). This opcode is treated as internal-only, yet its request path skips both the session check and the DELETE ACL check enforced by the regular delete path. As a resu...

Issue is caused by incomplete...

CVE-2026-59739

Apache ZooKeeper has an information disclosure vulnerability in the DataTree.setWatches() reconnect replay handler (SetWatches/SetWatches2). This is an incomplete fix for CVE-2024-23944 (ZOOKEEPER-4799): the prior patch added an ACL check in WatchManager.triggerWatch(), but DataTree.setWatches() ...
