{"apiVersion":"1.0","identifier":"CVE-2026-67440","description":"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.","publishedAt":"2026-08-18T20:17:22","lastModifiedAt":"2026-08-19T13:17:51","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-67440","cvssScore":6.9,"cvssVector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.0049,"riskScore":0.72,"affectedProduct":"FUXA","affectedVersions":"<=1.3.2","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-67440","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-67440","en":"https://www.redsauce.net/en/cves/CVE-2026-67440","fr":"https://www.redsauce.net/fr/cves/CVE-2026-67440","pt":"https://www.redsauce.net/pt/cves/CVE-2026-67440","de":"https://www.redsauce.net/de/cves/CVE-2026-67440","sk":"https://www.redsauce.net/sk/cves/CVE-2026-67440","el":"https://www.redsauce.net/el/cves/CVE-2026-67440"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-67440"}}
