What is CVE-2026-47721?

FUXA, a web-based process visualization software, is vulnerable to an authentication bypass that allows authenticated non-admin operators to alter device actions and delete schedules. This vulnerability results from insufficient enforcement of admin permissions for specific API endpoints, enabling unauthorized device-value manipulation and script execution typically restricted to administrators. The flaw allows scheduled actions to continue executing even after the operator’s session has ended, posing significant risks for device control and project data integrity. This issue has been addressed in version 1.3.2.
