Analysis

LiquidJS permite la ejecución de código arbitrario mediante el uso de plantillas maliciosas en versiones anteriores a la 10.26.0. Un atacante puede tomar control del servidor o del entorno de ejecución si logra inyectar contenido en el motor de renderizado. Es fundamental actualizar a la última versión para proteger aplicaciones web que utilicen este motor de plantillas.
