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)
