CVE-2026-4907Public exploitNetwork attack vector

SSRF via unchecked sitemap URL

Published Mar 27, 2026 · Updated Mar 27, 2026

Server-side request forgery in Page Replica e4a7f52e75093ee318b4d5a9a9db6751050d2ad0 allows remote authenticated users to make outbound requests. The /sitemap handler passes req.query.url directly to sitemap.fetch without checking the destination host, scheme, or network range. Low-privileged endpoint access is required; successful requests can reach internal services or metadata endpoints from the server.
