Full vulnerability record from the local CVENow database.

Description

A server-side request forgery vulnerability in Dub as of 2026-07-10 allows unauthenticated remote attackers to make the server issue HTTP requests to arbitrary internal or external hosts via the metatags edge endpoint. The endpoint fetches any caller-supplied URL without applying a denylist or requiring authentication. An attacker can use this to scan internal services or exfiltrate data from cloud metadata endpoints.

El punto final recupera cualquier URL proporcionada por el solicitante sin aplicar una lista de denegación ni requerir autenticación. Un atacante puede usar esto para escanear servicios internos o exfiltrar datos de puntos finales de metadatos en la nube."
