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.
