NewCVE-2026-82437 (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 Missing Authorization due to improper enforcement of access controls in the Logviewer process. An attacker can gain unauthorized access to sensitive daemon log files and metadata by sending requests to the affected endpoints after passing the configured servlet filter. This exposure allows retrieval of log content and metadata containing other tenants' topology names, owners, and configuration fragments.
Workaround
This vulnerability can be mitigated by placing the Logviewer behind a reverse proxy that restricts access to the daemon log endpoints and treating daemon log content as readable by any filter-authenticated user.
