# CVE-2026-25938: FUXA Unauthenticated Remote Code Execution in Node-RED Integration

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.5% , percentile 74: FIRST’s model estimates a 1.5% chance of exploitation activity in the next 30 days, higher than 74% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes fuxa-server (npm) >= 1.2.8, < 1.2.11, fixed in 1.2.11 . Check your lockfile, including transitive dependencies.

## What it is

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. From 1.2.8 through 1.2.10, an authentication bypass vulnerability in FUXA allows an unauthenticated, remote attacker to execute arbitrary code on the server when the Node-RED plugin is enabled. This has been patched in FUXA version 1.2.11.

## Affected packages

- npm `fuxa-server` >= 1.2.8, < 1.2.11 → fixed: 1.2.11

## Affected products (CVE record)

- frangoteam FUXA: >= 1.2.8, < 1.2.11

## Severity

- GitHub_M CVSS 4.0: 9.5 `CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`
- GitHub CVSS 4.0: 9.5 `CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.48% probability of exploitation activity in the next 30 days; percentile 74.
