{"schemaVersion":3,"id":"CVE-2026-84716","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A flaw was found in the automation-controller instance\n                  install-bundle endpoint. When a System Administrator downloads\n                  an execution/hop node's install bundle, the controller signs an\n                  X.509 certificate with the receptor mesh certificate authority\n                  in which the Common Name, DNS subject-alternative-name, and\n                  receptor node-id are taken verbatim from the caller-chosen\n                  instance hostname, with a hard-coded ten-year validity, a random\n                  serial, and no issuance log or revocation list. Because the\n                  hostname charset validator is case-insensitive while the\n                  uniqueness validator is case-sensitive, an administrator can\n                  register a case variant of an existing control node's hostname\n                  and obtain a mesh-CA-signed certificate that TLS peers, which\n                  match hostnames case-insensitively, accept as that control node.\n                  In managed/hosted deployments — where the customer holds\n                  controller superuser but the platform operator runs the mesh —\n                  this yields a long-lived, non-revocable mesh peer credential and,\n                  with an on-path position, TLS impersonation or interception of\n                  control/hybrid mesh nodes. It does not grant direct remote code\n                  execution, because receptor work submission is gated by a\n                  separate signing key not included in the bundle.","dates":{"published":"2026-09-23T19:40:28.390Z","modified":"2026-10-16T11:55:20.071Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.6,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.6,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.6,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00178,"percentile":0.06968,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-09-24T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00178,"percentile":0.06968}],"last30":[{"date":"2026-09-24T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00178,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00178,"percentile":0.06968}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry
