- VDE-2025-106Beckhoff: XSS Vulnerability in TwinCAT 3 HMI Server2026-01-26csaf · beckhoff_psirtDE
An optional package of the TwinCAT 3 XAR installs the TwinCAT 3 HMI Server on a device. It provides a server configuration page which can be accessed by administrative users only. When such an administrator accesses the server configuration page it is possible to upload arbitrary content into the CUSTOM_CSS field which is then persisted on the device and later returned and rendered with each login and error page. Please note that administrators have the access rights to modify any content on the HMI server, for example, via the server configuration page. Therefore, administrators would have to act maliciously to exploit this vulnerability.
