CVE-2026-72552

Estado: AplazadaAlta (7.5)—

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.
