What is CVE-2026-25752?

FUXA, a web-based Process Visualization software, is susceptible to an authorization bypass vulnerability that allows unauthenticated remote attackers to manipulate device tags through WebSockets. By exploiting this weakness, attackers can circumvent role-based access controls, potentially enabling them to overwrite device tags or disable communication drivers. This exposes ICS/SCADA environments to further threats, including the potential manipulation of physical processes and disruption of connected devices. The vulnerability affects FUXA versions up to 1.2.9 and has been addressed in version 1.2.10.
