CVE-2025-11361Public exploitNetwork attack vector

Authenticated SSRF via unrestricted AI image fetch

Published Oct 18, 2025 · Updated Oct 18, 2025

Server-side request forgery in Essential Blocks for Gutenberg 5.7.1 and earlier allows remote authenticated users to access internal services. The eb_save_ai_generated_image AJAX handler passes an attacker-controlled image_url to wp_remote_get() without restricting loopback, private, link-local, or metadata addresses, then stores the response body as media without verifying that it is an image. Author-level access and a valid admin nonce are required; successful requests can disclose internal responses or perform actions accepted by reachable services.
