  "details": "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 1.0.29, MCPHub's PUT /api/system-config endpoint (handler updateSystemConfig) performs no authorization check. It is protected only by the app-wide authentication middleware and a rate limiter — it never inspects req.user.isAdmin. This issue has been patched in version 1.0.29.",
