Prior to version 0.12.15, the POST /api/servers and PUT /api/servers/:name endpoints in MCPHub create/update MCP server configurations and then immediately spawn the configured stdio process via child_process.spawn. Authentication is required, but there is no authorization check restricting these endpoints to admins, and there is no allowlist/sanitization on the command and args fields. As a result, any authenticated non-admin user can submit a server configuration with command:\"/bin/sh\" (or any other binary) and arbitrary args, causing MCPHub to execute the attacker-controlled process as the MCPHub server\u0027s OS user (commonly root in the published Docker image and in npx/systemd deployments). This issue has been patched in version 0.12.15."
