An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-67443 in the wild and no public exploit code.\n\nAffected product: frangoteam FUXA. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-67443/ (Markdown: https://insights.sbomify.com/CVE-2026-67443/index.md)","id":"CVE-2026-67443","markdown":"https://insights.sbomify.com/CVE-2026-67443/index.md","name":"CVE-2026-67443","record":{"aliases":["GHSA-5h5x-9h7x-23f4"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"SCADA HMI software","requires_auth":"none","summary":"Unauthenticated attackers can bypass Node-RED authorization in FUXA to deploy malicious scripts and execute arbitrary code on the host system.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"FUXA: Unauthenticated guest JWT bypasses Node-RED secure-mode authorization gate (Remote Script Execution)","id":"CVE-2026-67443","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Mailpit: SMTP command parser buffers unbounded command lines before syntax rejection","id":"CVE-2026-67445"},"packages":[],"prev":{"headline":"FUXA Business Logic Flaw: Role Deletion Without User Assignment Cleanup","id":"CVE-2026-67442"},"products":["FUXA"],"published":"2026-08-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-21","vendors":["frangoteam"]},"summary":"Unauthenticated attackers can bypass Node-RED authorization in FUXA to deploy malicious scripts and execute arbitrary code on the host system.","url":"https://insights.sbomify.com/CVE-2026-67443/"}
