Affected scope and exposure questions

The current feed maps org.apache.zookeeper:zookeeper (maven). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
Package	Affected range	Fixed version
org.apache.zookeeper:zookeepermaven	>=3.9.0 <3.9.4	3.9.4

Recommended response

Check inventory. Check lockfiles and deployed manifests for org.apache.zookeeper:zookeeper.
Review the reported fix. Update org.apache.zookeeper:zookeeper to 3.9.4 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source description

Improper permission checks in the AdminServer allow an authenticated client with insufficient privileges to invoke the `snapshot` and `restore` commands. The intended requirement is authentication and authorization on the root path (`/`) with **ALL** permission for these operations; however, affected versions permit invocation without that level of authorization. The primary risk is disclosure of cluster state via snapshots to a lesser-privileged client. * **Affected:** `org.apache.zookeeper:zookeeper` 3.9.0 through 3.9.3. * **Fixed:** 3.9.4 (ZOOKEEPER-4964 “check permissions individually during admin server auth”). * **Mitigations:** * Disable both commands (`admin.snapshot.enabled`, `admin.restore.enabled`). * Disable AdminServer (`admin.enableServer`). * Ensure the root ACL is not open; note that ZooKeeper ACLs are not recursive. * Upgrade to 3.9.4.
