{"id":"CVE-2026-67443","state":"PUBLISHED","title":"FUXA: Unauthenticated guest JWT bypasses Node-RED secure-mode authorization gate (Remote Script Execution)","description":"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.","publishedAt":"2026-08-18T20:06:15.514Z","updatedAt":"2026-08-21T19:12:19.610Z","severity":{"score":9.2,"label":"Critical","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["frangoteam FUXA"],"affected":[{"vendor":"frangoteam","product":"FUXA","versions":[{"version":"< 1.3.3","status":"affected"}]}],"references":["https://github.com/frangoteam/FUXA/security/advisories/GHSA-5h5x-9h7x-23f4","https://github.com/frangoteam/FUXA/pull/2393","https://github.com/frangoteam/FUXA/commit/e0b553cddb55613b890341270eb17eb586f8cab5","https://github.com/frangoteam/FUXA/releases/tag/v1.3.3"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:41.951Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/67xxx/CVE-2026-67443.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-67443","state":"PUBLISHED","datePublished":"2026-08-18T20:06:15.514Z","dateUpdated":"2026-08-21T19:12:19.610Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-29T15:07:24.992Z"},"containers":{"cna":{"title":"FUXA: Unauthenticated guest JWT bypasses Node-RED secure-mode authorization gate (Remote Script Execution)","descriptions":[{"lang":"en","value":"FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software.
