In versions 0.27.0 and earlier, when MCP Gateway runs in sse or streaming transport mode, it is vulnerable to DNS rebinding. An attacker who can get a victim to visit a malicious website or be served a malicious advertisement can perform browser-based exploitation of MCP servers executing behind the gateway, including manipulating tools or other features exposed by those MCP servers. MCP Gateway is not affected when running in the default stdio mode, which does not listen on network ports. Version 0.28.0 fixes this issue."},{"lang":"es","value":"MCP Gateway permite la ejecución y el despliegue fácil y seguro de servidores MCP. En las versiones 0.27.0 y anteriores, cuando MCP Gateway se ejecuta en modo de transporte sse o streaming, es vulnerable a DNS rebinding. Un atacante que puede lograr que una víctima visite un sitio web malicioso o que se le muestre un anuncio malicioso puede realizar una explotación basada en el navegador de servidores MCP que se ejecutan detrás del gateway, incluyendo la manipulación de herramientas u otras características expuestas por esos servidores MCP.
