      "value": "Werkzeug is a Web Server Gateway Interface web application library. Applications using `werkzeug.formparser.MultiPartParser` corresponding to a version of Werkzeug prior to 3.0.6 to parse `multipart/form-data` requests (e.g. all flask applications) are vulnerable to a relatively simple but effective resource exhaustion (denial of service) attack. A specifically crafted form submission request can cause the parser to allocate and block 3 to 8 times the upload size in main memory. There is no upper limit; a single upload at 1 Gbit/s can exhaust 32 GB of RAM in less than 60 seconds. Werkzeug version 3.0.6 fixes this issue."

      "value": "Werkzeug es una librer\u00eda de aplicaciones web de interfaz de puerta de enlace de servidor web. Las aplicaciones que utilizan `werkzeug.formparser.MultiPartParser` correspondiente a una versi\u00f3n de Werkzeug anterior a la 3.0.6 para analizar solicitudes `multipart/form-data` (por ejemplo, todas las aplicaciones Flask) son vulnerables a un ataque de agotamiento de recursos (denegaci\u00f3n de servicio) relativamente simple pero efectivo. Una solicitud de env\u00edo de formulario manipulada espec\u00edficamente puede hacer que el analizador asigne y bloquee de 3 a 8 veces el tama\u00f1o de carga en la memoria principal. No hay un l\u00edmite superior; una sola carga a 1 Gbit/s puede agotar 32 GB de RAM en menos de 60 segundos. La versi\u00f3n 3.0.6 de Werkzeug corrige este problema."
