CVE-2026-94125
Apache Storm: Supervisor page discloses worker placement of other users' topologies
Nimbus returns the worker placement of every topology running on a supervisor, including the host, port, owner and resource assignment of topologies the caller is not authorized to read. In a multi-tenant cluster, an authenticated user who is allowed to access Nimbus can learn where the workers of other users' topologies run. Users are recommended to upgrade to version 3.2.0, which fixes the issue.
