      "value": "SAP Approuter does not enforce cross-site request forgery protection on the authentication flow by default. An unauthenticated attacker could craft a malicious link and trick a victim into following it. Successful exploitation could allow the attacker to bind the victim's session to an attacker-controlled identity, resulting in a low impact on integrity. There is no impact on confidentiality and availability."

      "value": "SAP Approuter no aplica protección contra falsificación de petición en sitios cruzados en el flujo de autenticación por defecto. Un atacante no autenticado podría crear un enlace malicioso y engañar a una víctima para que lo siga. La explotación exitosa podría permitir al atacante vincular la sesión de la víctima a una identidad controlada por el atacante, resultando en un impacto bajo en la integridad. No hay impacto en la confidencialidad y disponibilidad."
