CVE-2026-46697Public exploitNetwork attack vector

Unauthenticated network-resource disclosure via unrestricted REST proxy

Published Jun 11, 2026 · Updated Jun 11, 2026

SSRF in Fediverse Embeds before 1.5.8 allows remote attackers to read network resources through an unauthenticated WordPress REST route. The ftf/media-proxy handler decodes its URL parameter, passes it to wp_remote_get without enforcing the computed domain decision, and returns the complete response body. Any anonymous visitor who can reach the route can make the WordPress server retrieve and disclose HTTP content accessible from its network position.
