UBUNTU-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-2026-84501 Apache ZooKeeper: Operational log forgery via newline injection in EnsembleAuthenticationProvider
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-2026-84501
An unauthenticated attacker can inject arbitrary fake log lines into Apache ZooKeeper 's operational log by sending a crafted add_auth("ensemble", ...) request containing newline characters (\n ). The vulnerability occurs because the EnsembleAuthenticationProvider.handleAuthentication() method lo...
CVE-2026-84439
An unauthenticated attacker can perform a log injection attack on Apache ZooKeeper (versions 3.9.0 through 3.9.5 and 3.8.0 through 3.8.6 ) when audit logging is enabled (zookeeper.audit.enable=true). By sending a digest authentication request containing tab characters ( ) in the username, an atta...
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-2026-84439 Apache ZooKeeper: Audit log injection via unsanitized output from multiple sources
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.

CVE-2026-79993 Apache ZooKeeper: Missing ACL check on deleteContainer opcode allows unauthorized deletion of any empty persistent/container znode
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-2026-79993
Apache ZooKeeper versions 3.9.0 through 3.9.5 and 3.8.0 through 3.8.6 are vulnerable to an authorization bypass due to a missing ACL check on the deleteContainer opcode (0x14/20). While this opcode is intended for internal use and lacks an official client API, an attacker can open a plain TCP ses...
