NewCVE-2026-82434 (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 storm.zookeeper.topology.auth.payload configuration parameter. An attacker can gain unauthorized access to sensitive ZooKeeper credentials by obtaining read-only topology permissions or accessing logs where the credential was inadvertently recorded. This allows the attacker to forge or remove cluster state information, such as worker heartbeats, backpressure, and error state, potentially impacting the integrity and availability of the system. The credential is not sufficient to modify assignments.
Workaround
This vulnerability can be mitigated by rotating the storm.zookeeper.topology.auth.payload for existing topologies, reviewing retained logs and support bundles for exposed values, and restricting read-only topology permissions to trusted principals.
