The\n                  unauthenticated health-check endpoint /api/v2/ping/\n                  (ApiV2PingView, AllowAny) over-serializes RBAC-gated\n                  automation-mesh data into its anonymous response, exposing the\n                  full instance inventory (node hostnames, node types, UUIDs,\n                  heartbeats, capacities, and exact versions), all instance-group\n                  names and membership, the deployment install UUID, and the\n                  active control node. A remote, unauthenticated attacker can use\n                  this to map the control plane and fingerprint software versions\n                  for targeted attacks. This flaw affects confidentiality only;\n                  it does not expose secrets, credentials, or tenant data.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:71114** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71114)\n- **RHSA-2026:71113** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 for RHEL 9 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71113)\n- **RHSA-2026:71179** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71179)\n- **RHSA-2026:71177** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.7 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71177)","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
