CVE-2026-63313Public exploitNetwork attack vector

Internal data disclosure via unrestricted web fetch

Published Jul 23, 2026 · Updated Jul 23, 2026

SSRF in 9Router before 0.4.72 allows remote authenticated users to read internal HTTP resources through /v1/web/fetch. The handler checks the user-supplied url only with new URL(), then sends it to a configured scraping provider without blocking private, loopback, link-local, metadata, or internal hosts. A configured provider and authenticated or local access are required; returned responses expose reachable internal services and cloud metadata credentials without permitting direct data modification or service interruption.
