      "value": "In consul-mcp-server, versions 0.1.0 up to 0.1.3 did not restrict how the Consul backend address was supplied, allowing a connected client to override the server's configured Consul address via a request header. This may allow a malicious client to redirect the server's Consul API traffic to an attacker-controlled endpoint, potentially exfiltrating the Consul token configured on the server. This vulnerability, CVE-2026-16328, is fixed in consul-mcp-server 0.1.4."

      "value": "En consul-mcp-server, las versiones 0.1.0 hasta la 0.1.3 no restringían cómo se suministraba la dirección del backend de Consul, permitiendo a un cliente conectado anular la dirección de Consul configurada del servidor a través de una cabecera de solicitud. Esto puede permitir a un cliente malicioso redirigir el tráfico de la API de Consul del servidor a un endpoint controlado por un atacante, potencialmente exfiltrando el token de Consul configurado en el servidor. Esta vulnerabilidad, CVE-2026-16328, está corregida en consul-mcp-server 0.1.4."
