CVE-2026-124495
Published:November 11, 2026
Updated:November 12, 2026
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.
