Summary
FUXA version 1.3.2 and earlier has a vulnerability in the allowDashboard authorization gate that allows a remote unauthenticated attacker to obtain a signed guest token and access the Node-RED editor and flow deployment API. The attacker can deploy malicious nodes or execute scripts, gaining control over project data, configuration, and potentially the operating system.
Risk Assessment
The attack can lead to full compromise of the SCADA/HMI system, including data theft, modification of industrial processes, and execution of system commands, posing a serious threat to critical infrastructure.
Recommendation
Update FUXA to version 1.3.3 or later, which includes the fix. Additionally, restrict network access to the server and monitor Node-RED activity.
Other vulnerabilities in FUXA
See all- CVE-2026-67442Low
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.3, DELETE /api/roles removes role definitions but does not remove the deleted role identifier from user's info.roles array or runtime usersMap cache. This can lead to retained authorization rights after admin revocation.
- CVE-2026-67440Medium
FUXA version 1.3.2 and earlier does not check isSocketAdminAuthorized for certain Socket.IO events (DEVICE_BROWSE, DEVICE_NODE_ATTRIBUTE, HOST_INTERFACES, DEVICE_TAGS_REQUEST) when secureEnabled is true. A remote unauthenticated or guest user can collect system-discovery information not required for normal HMI viewing.
- CVE-2026-65985Medium
FUXA version 1.3.2 and earlier allows an authenticated non-admin user to control property.address in the device-webapi-request handler, causing the FUXA server to issue outbound HTTP/HTTPS requests and return the response to the attacker. This leads to an SSRF vulnerability.
- CVE-2026-65984High
FUXA version 1.3.2 and earlier improperly handled session refresh, allowing an attacker with a previously issued privileged refresh cookie or access token to continue minting privileged JWTs even after account deletion, disablement, role removal, or demotion. This enabled continued unauthorized access to user management, project manipulation, runtime configuration, and backdoor-account creation. The issue is fixed in version 1.3.3.
- CVE-2026-47721Medium
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, POST /api/scheduler and DELETE /api/scheduler do not consistently enforce admin permissions. An authenticated non-admin operator can create or alter deviceActions or delete schedules, gaining access to device-value changes and server-side script execution.
- CVE-2026-47720Medium
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, the escapeTdString function does not escape backslashes, allowing a remote unauthenticated attacker to inject SQL via crafted sids tag identifiers. This can expose historical PLC tag values and device names.
- CVE-2026-47719High
FUXA before version 1.3.2 has a vulnerability allowing a remote unauthenticated attacker to perform SSRF (Server-Side Request Forgery) via the DEVICE_WEBAPI_REQUEST and DEVICE_PROPERTY Socket.IO handlers. By manipulating property.address or endpoint connection data, the attacker can make the server call axios.get against arbitrary HTTP/HTTPS destinations, including internal services, cloud metadata, OPC UA, or ODBC services. The issue is fixed in version 1.3.2.
- CVE-2026-47718Medium
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. When `secureEnabled=true`, FUXA `1.3.0-2773` still allows guest and invalid-token requests to read project, alarms, and scheduler APIs. Version 1.3.1 fixes this issue.
- CVE-2026-47717High
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In fuxa-server version 1.3.0, the GET /api/project endpoint exposes sensitive project configuration data to guest-context requests even when secureEnabled is enabled. Version 1.3.1 fixes the issue.
- CVE-2026-72586High
A missing authentication vulnerability in FUXA through 1.3.3 allows an unauthenticated remote attacker to query all historical sensor data via the DAQ_QUERY Socket.IO event. When secureEnabled=true, all other sensitive Socket.IO events (DEVICE_BROWSE, HOST_INTERFACES, DEVICE_TAGS_REQUEST, etc.) call isSocketAdminAuthorized to verify the connection token, but the DAQ_QUERY handler in server/runtime/index.js lacks this check entirely.
Original NVD description (English source)
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.
