{"id":"CVE-2026-67443","summary":"FUXA: Unauthenticated guest JWT bypasses Node-RED secure-mode authorization gate (Remote Script Execution)","details":"FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the allowDashboard authorization gate in server/integrations/node-red/index.js calls authJwt.verify for /nodered without inspecting the decoded identity. When nodeRedEnabled is true, secureEnabled is true, and nodeRedAuthMode is secure, a remote unauthenticated attacker can obtain a signed guest token from POST /api/heartbeat and use it to access the RED.httpAdmin editor and flow deployment API. Because the Node-RED configuration has no second adminAuth gate, the attacker can deploy function nodes or invoke fuxa.runScript and runtime.scriptsMgr.runScript, gaining control of FUXA project data, configuration, scripts, filesystem-capable runtime helpers, and potentially operating-system commands when nodeRedUnsafeModules is enabled. This issue is fixed in version 1.3.3.","aliases":["GHSA-5h5x-9h7x-23f4"],"modified":"2026-08-23T03:42:30.455483008Z","published":"2026-08-18T20:06:15.514Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67443.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-2026-67443.json"},{"type":"ADVISORY","url":"https://github.com/frangoteam/FUXA/security/advisories/GHSA-5h5x-9h7x-23f4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67443"},{"type":"FIX","url":"https://github.com/frangoteam/FUXA/commit/e0b553cddb55613b890341270eb17eb586f8cab5"},{"type":"FIX","url":"https://github.com/frangoteam/FUXA/pull/2393"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/frangoteam/fuxa","events":[{"introduced":"0"},{"fixed":"e0b553cddb55613b890341270eb17eb586f8cab5"},{"fixed":"68a635aa69608283428de2c7fe9ecf475c5773ab"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.3.3"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"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-2026-67443.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
