CVE-2026-65985 — FUXA: SSRF hardening for `device-webapi-request`

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the device-webapi-request Socket.IO handler in server/runtime/index.js permits an authenticated non-admin runtime user to control property.address, causing the FUXA server to issue an outbound HTTP or HTTPS request and return the response body to the requesting socket. The attacker can use the server as a read SSRF oracle against reachable internal services or cloud metadata endpoints, with impact depending on the FUXA host's deployment network. This issue is fixed in version 1.3.3.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Frangoteam Fuxa).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (ssrf), errors and authentication anomalies.
