CVE-2026-15189Public exploitNetwork attack vector

Authenticated SSRF via unrestricted media URL fetch

Published Jul 9, 2026 · Updated Jul 9, 2026

Server-side request forgery in Aerostack MCP Catalog allows remote authenticated users to send requests to attacker-chosen destinations. The mcp-whatsapp upload_media handler passes the caller-controlled media_url directly to fetch without scheme, host, IP, port, or redirect validation. Access to an authenticated MCP workspace is required; successful exploitation reaches services available from the hosted worker's network context.
