Description
SvelteKit before 3.0.0 contains a server-side request forgery vulnerability that allows remote attackers to reach internal services because self-fetch fallbacks follow HTTP redirects automatically. Attackers can manipulate the Host or forwarded headers to point fallback requests at their server, which redirects them to internal services.
