NewCVE-2026-82438 (opens in a new tab)How to fix?
Upgrade org.apache.storm:storm-webapp to version 3.1.0 or higher.
Overview
Affected versions of this package are vulnerable to Origin Validation Error via the handling of HTTP responses in the UI, Logviewer, and DRPC components. An attacker can access sensitive cluster, topology, and log data by enticing an authenticated user to visit a malicious web page that exploits improper CORS and JSONP configurations.
Workaround
This vulnerability can be mitigated by placing the affected HTTP endpoints behind a reverse proxy that strips Access-Control-Allow-Origin and Access-Control-Allow-Credentials from responses and rejects requests carrying a callback parameter.
