CVE-2026-114062 · SvelteKit before 3.0.0 SSRF via Redirects in Server-Side Self-Fetch Fallbacks

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
