CVE-2026-79747

MCPHub vulnerable to SSRF: a non-admin user can make mcphub request arbitrary URLs and read the response (OpenAPI proxy + transport dial)

Published Aug 31, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 1.0.32, an authenticated non-admin user can register a server pointing at an arbitrary URL and make the hub issue server-side requests to it, with no egress filtering (no block of loopback / RFC1918 / link-local 169.254.0.0/16). Via the OpenAPI proxy path the response body is returned to the caller (full, reflected SSRF); via the SSE/streamable-http transport the request is sent blind. This issue has been patched in version 1.0.32.
