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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-497"],"references":["https://access.redhat.com/errata/RHSA-2026:71113","https://access.redhat.com/errata/RHSA-2026:71114","https://access.redhat.com/errata/RHSA-2026:71177","https://access.redhat.com/errata/RHSA-2026:71179","https://access.redhat.com/security/cve/CVE-2026-84712"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-84712","score":0.00388,"percentile":0.32879,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
