A flaw was found in the automation-controller API. The unauthenticated health-check endpoint /api/v2/ping/ (ApiV2PingView, AllowAny) over-serializes RBAC-gated automation-mesh data into its anonymous response, exposing the full instance inventory (node hostnames, node types, UUIDs, heartbeats, capacities, and exact versions), all instance-group names and membership, the deployment install UUID, and the active control node. A remote, unauthenticated attacker can use this to map the control plane and fingerprint software versions for targeted attacks. This flaw affects confidentiality only; it does not expose secrets, credentials, or tenant data.
