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.

An attacker can use this to scan internal services or exfiltrate data from cloud metadata endpoints.
