Doc Text:
A flaw was found in Apache Storm. This vulnerability can lead to information disclosure when an authenticated user queries the central management service, Nimbus. In a multi-tenant cluster, the service fails to enforce proper authorization on topology placement data, exposing worker hostnames, network ports, owner identities, and resource allocations belonging to other tenants.

Description OSIDB Bzimport 2026-11-11 12:41:18 UTC
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.
