{"id":"CVE-2026-67440","summary":"FUXA: Unauthenticated Socket.IO read events","details":"FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. 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.","aliases":["GHSA-rh5p-m38p-2w75"],"modified":"2026-08-21T03:30:41.474415065Z","published":"2026-08-18T20:03:38.786Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67440.json"},"references":[{"type":"WEB","url":"https://github.com/frangoteam/FUXA/releases/tag/v1.3.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67440.json"},{"type":"ADVISORY","url":"https://github.com/frangoteam/FUXA/security/advisories/GHSA-rh5p-m38p-2w75"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67440"},{"type":"FIX","url":"https://github.com/frangoteam/FUXA/commit/4fa47d0a2a856ed34f427f472fb4450f86e7749b"},{"type":"FIX","url":"https://github.com/frangoteam/FUXA/pull/2379"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/frangoteam/fuxa","events":[{"introduced":"0"},{"fixed":"4fa47d0a2a856ed34f427f472fb4450f86e7749b"},{"fixed":"68a635aa69608283428de2c7fe9ecf475c5773ab"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.3.3"}]}}],"versions":["v1.3.2","v1.3.1","v1.3.0","v1.2.9","v1.2.8","v1.2.7","v1.2.6","v1.2.4","untagged-fb3c7751ca725cb671dd","v1.2.1","v1.2.0","v1.1.19","v.1.1.18","v1.1.17","v1.1.16","v1.1.15","v1.1.14","v1.1.13","v1.1.12","v1.1.11-3","v1.1.11-2","v1.1.11","v1.1.10","v1.1.9","v1.1.8","v1.1.7","v1.1.6","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.01","v1.0.11","v1.0.10","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1_alfa","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-67440.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
