CVE-2026-47719

FUXA (version 1.3.2-2809) has an authorization bypass vulnerability in the /nodered functionality. A specially crafted HTTP request can lead to arbitrary code execution, and an attacker can trigger it with an unauthenticated HTTP request.

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.

An authorization bypass vulnerability exists in the /api/runscript functionality of FUXA (version 1.3.2-2809). A specially crafted HTTP request can lead to execution of a privileged operation, and an attacker can trigger this vulnerability with an unauthenticated HTTP request.

An information disclosure vulnerability exists in the /nodered/fuxa/scripts functionality of FUXA (version 1.3.2-2809). A specially crafted HTTP request can lead to an information leak, and an attacker can trigger this vulnerability with an unauthenticated HTTP request.

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.

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.

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.

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.

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.

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.
