Doc Text:
A flaw was found in Apache Storm. This vulnerability allows an authenticated user authorized to submit topologies to cause an information disclosure. When worker processes run under the topology owner's identity, the Logviewer service improperly follows file links placed in a worker's log directory. An attacker can exploit this behavior to view log files from other users' topologies as well as other system files readable by the Logviewer process.

Description OSIDB Bzimport 2026-11-11 12:41:31 UTC 
When workers run as the topology owner, the Logviewer serves files that a worker has placed in its own log directory as links to other files. A user who is allowed to submit topologies can read the worker logs of other users' topologies, and other files the Logviewer process can read. Users are recommended to upgrade to version 3.2.0, which fixes the issue.
