      "value": "tarteaucitron.js is a compliant and accessible cookie banner. Prior to 1.33.0, tarteaucitron.cookie.purge() is called on any element with the purgeBtn class and does not check whether the element is a legitimate tarteaucitron button or whether the cookie corresponds to a service handled by tarteaucitron. If an attacker can write HTML with data attributes, an element with data-cookie can silently delete a non-HttpOnly cookie with a known name when clicked by a user. This issue is fixed in version 1.33.0."

Antes de 1.33.0, tarteaucitron.cookie.purge() se llama en cualquier elemento con la clase purgeBtn y no verifica si el elemento es un botón legítimo de tarteaucitron o si la cookie corresponde a un servicio gestionado por tarteaucitron. Si un atacante puede escribir HTML con atributos de datos, un elemento con data-cookie puede eliminar silenciosamente una cookie no HttpOnly con un nombre conocido cuando un usuario hace clic en él. Este problema está solucionado en la versión 1.33.0."
