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.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-497"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:71113","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:71114","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:71177","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2026:71179","tags":[]},{"url":"https://access.redhat.com/security/cve/CVE-2026-84712","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527196","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
