CVE-2026-82433Network attack vectorHinoki check available

Credential disclosure via unredacted daemon configuration

Published Sep 14, 2026 · Updated Sep 14, 2026

Information disclosure in Apache Storm Nimbus and UI 3.0.0 allows remote attackers to read daemon credentials through configuration APIs. getNimbusConf returns the complete daemon configuration without redaction, while the UI configuration endpoint lacks AuthNimbusOp and proxies the request as the UI daemon. Nimbus requires user-level authorization, but any requester passing ui.filter can obtain configured ZooKeeper authentication data and TLS store passwords.
