# CVE-2026-25894: FUXA Unauthenticated Remote Code Execution via Hardcoded JWT Secret in Default Configuration

**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 1.4% , percentile 72: FIRST’s model estimates a 1.4% chance of exploitation activity in the next 30 days, higher than 72% 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) <= 1.2.9, fixed in 1.2.10 . Check your lockfile, including transitive dependencies.

## What it is

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An insecure default configuration in FUXA allows an unauthenticated, remote attacker to gain administrative access and execute arbitrary code on the server. This affects FUXA through version 1.2.9 when authentication is enabled, but the administrator JWT secret is not configured. This issue has been patched in FUXA version 1.2.10.

## Affected packages

- npm `fuxa-server` <= 1.2.9 → fixed: 1.2.10

## Affected products (CVE record)

- frangoteam FUXA: < 1.2.10

## Severity

- GitHub_M CVSS 4.0: 9.5 `CVSS:4.0/AV:N/AC:H/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:H/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 no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.39% probability of exploitation activity in the next 30 days; percentile 72.
