In 1.3.2 and earlier, the DEVICE_BROWSE, DEVICE_NODE_ATTRIBUTE, HOST_INTERFACES, and DEVICE_TAGS_REQUEST handlers in server/runtime/index.js return device-discovery, node-attribute, host-network-interface, and device-tag metadata without isSocketAdminAuthorized when secureEnabled is true. A remote unauthenticated or guest user can invoke these metadata-oriented Socket.IO events and collect system-discovery information that is not required for normal public HMI viewing, while ordinary device status, value, alarm, and dashboard events remain intentionally public. This issue is fixed in version 1.3.3."}],"source":{"advisory":"GHSA-rh5p-m38p-2w75","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-19T13:12:16.851308Z","id":"CVE-2026-67440","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-19T13:12:33.433Z"}}]}}
