AI-suggested
A fix is available in Apache ZooKeeper version 3.9.4. Users should upgrade to this version to fully remediate the vulnerability. Alternatively, mitigations include disabling the snapshot and restore commands via the 'admin.snapshot.enabled' and 'admin.restore.enabled' settings, disabling the AdminServer entirely with 'admin.enableServer', and ensuring the root ACL is not open, noting that ZooKeeper ACLs are not recursive.
Description
Apache ZooKeeper versions 3.9.0 through 3.9.3 have an insufficient permission check vulnerability in the AdminServer's snapshot and restore commands. Authenticated clients with lower privileges than intended can invoke these commands, potentially disclosing cluster state information. The issue is fixed in version 3.9.4.
