CVE-2026-124495
Apache Storm: Logviewer follows worker symlinks across topology ACLs
apache software foundation apache storm: no CVSS score yet.
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.
