CVE-2026-84179: Apache Storm Nimbus, Apache Storm UI: Disclosure of Unredacted Merged Daemon Configuration via the Topology Page
Apache Storm Nimbus/UI 3.0.0 leaks unredacted merged daemon configuration through the topology page, exposing secrets to UI users.
CVE-2026-84179 (severity: important) affects Apache Storm Nimbus (storm-server) and Storm UI (storm-webapp) versions 3.0.0 before 3.1.0. The getTopologyPageInfo function merged the Nimbus daemon configuration with topology configuration and returned it unredacted in the topology_conf field of TopologyPageInfo, which the Storm UI copied verbatim. This can expose sensitive daemon configuration values to topology users.
