Estado: ModificadaMedia (5.5)—

El paquete link-preview-js versiones anteriores a 2.1.16, es vulnerable a un ataque de tipo Server-side Request Forgery (SSRF) que permite a atacantes enviar peticiones arbitrarias a la red local y leer la respuesta. Esto es debido a una protección defectuosa de reenganche de DNS
