NewCVE-2026-84179 (opens in a new tab)How to fix?
Upgrade org.apache.storm:storm-server to version 3.1.0 or higher.
Overview
org.apache.storm:storm-server is a distributed realtime computation system.
Affected versions of this package are vulnerable to Insufficiently Protected Credentials via the getTopologyPageInfo process. An attacker can access sensitive daemon configuration data, including authentication payloads and passwords, by sending requests to the topology page endpoints. This is only exploitable if the attacker is listed in topology.readonly.users or topology.readonly.groups under SimpleACLAuthorizer.
Workaround
This vulnerability can be mitigated by removing any principal not trusted with cluster credentials from topology.readonly.users, topology.readonly.groups, topology.users, and topology.groups, and by rotating the ZooKeeper authentication payload and any TLS keystore or truststore passwords that were exposed.
