Summary
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the DEVICE_BROWSE, DEVICE_NODE_ATTRIBUTE, HOST_INTERFACES, and DEVICE_TAGS_REQUEST handlers in server/runtime/index.js return device-discovery, node-attribute, host-network-interface, and device-tag metadata without isSocketAdminAuthorized when secureEnabled is true. A remote unauthenticated or guest user can invoke these metadata-oriented Socket.IO events and collect system-discovery information that is not required for normal public HMI viewing, while ordinary device status, value, alarm, and dashboard events remain intentionally public. This issue is fixed in version 1.3.3.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of frangoteam/FUXA published their own advisory on GitHub. Reviewed sources take precedence over it.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
