CVE-2026-104629

Estado: Pendiente de análisisAlta (7.7)—

Un mecanismo de carga de componentes en openPDC y openHistorian construirá y ejecutará cualquier tipo especificado, que puede ser un componente inválido para cargar. Un atacante con una cuenta de usuario autenticada y la capacidad de colocar un archivo en el sistema de archivos del host puede utilizar esto para ejecutar código de constructor arbitrario, y este código se ejecuta con los privilegios de la cuenta de servicio afectada.
