What is CVE-2026-25752?
CVE-2026-25752 is a critical missing authorization vulnerability in frangoteam FUXA, published on 6 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An authorization bypass vulnerability in FUXA allows an unauthenticated, remote attacker to modify device tags via WebSockets. Exploitation allows an unauthenticated, remote attacker to bypass role-based access controls and overwrite arbitrary device tags or disable communication drivers, exposing connected ICS/SCADA environments to follow-on actions. This may allow an attacker to manipulate physical processes and disconnected devices from the HMI. This affects FUXA through version 1.2.9. This issue has been patched in FUXA version 1.2.10.
Weakness: CWE-862
