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

Noroxi assessment

Priority: Monitor (action score 38/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 64.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: fuxa-server (npm) 1.2.11.

Low priority for now. Upgrade to fuxa-server (npm) 1.2.11 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
