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.","categories":["Operating systems"],"product":"Red Hat Ansible Automation Platform 2.5 for RHEL 8","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84712","source_modified_at":"2026-10-16T11:55:07.623Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2.5 for RHEL 8","vendor":"Red Hat","versions":[{"version":"0:4.6.33-1.el8ap","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84712","source_modified_at":"2026-10-16T11:55:07.623Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2.5 for RHEL 9","vendor":"Red Hat","versions":[{"version":"0:4.6.33-1.el9ap","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84712","source_modified_at":"2026-10-16T11:55:07.623Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2.6 for RHEL 9","vendor":"Red Hat","versions":[{"version":"0:4.7.17-1.el9ap","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84712","source_modified_at":"2026-10-16T11:55:07.623Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2.6","vendor":"Red Hat","versions":[{"version":"1789673739","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84712","source_modified_at":"2026-10-16T11:55:07.623Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Ansible Automation Platform 2.7","vendor":"Red Hat","versions":[{"version":"1789580684","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00337,"percentile":0.25869,"score_date":"2026-10-23"},"published_at":"2026-09-23T19:40:22.582Z","modified_at":"2026-10-16T11:55:07.623Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-84712","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T11:55:07.623Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-84712","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:71113","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:71114","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:71177","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:71179","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-84712","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527196","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-24T14:29:05.289631Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-16T11:55:07.623Z","content_hash":"1ba0f55025579a0b04157c0a990fb645b1d373591ea7e3d9812f2bc45e5963fa"}}
