0 CVE-2026-59739 is a missing authorization vulnerability in Apache ZooKeeper that allows information disclosure of ACL-restricted paths. An attacker can register watches on non-existent paths and, upon reconnecting after those paths are created with restricted ACLs, discover the existence of these paths. The vulnerability arises from an incomplete fix for a previous issue, where the ACL check was not enforced during the SetWatches reconnect replay. Although the data within the znode is not exposed, the path itself may contain sensitive information such as usernames or login IDs. The issue affects Apache ZooKeeper versions 3.8.0 through 3.8.6 and 3.9.0 through 3.9.5. Upgrading to versions 3.8.7 or 3.9.6 addresses the vulnerability.
