    {

      "value": "A flaw was found in libsoup. When handling cookies, libsoup clients mistakenly allow cookies to be set for public suffix domains if the domain contains at least two components and includes an uppercase character. This bypasses public suffix protections and could allow a malicious website to set cookies for domains it does not own, potentially leading to integrity issues such as session fixation."
    },
    {
      "lang": "es",
      "value": "Se detectó una falla en libsoup. Al gestionar cookies, los clientes de libsoup permiten erróneamente la configuración de cookies para dominios con sufijos públicos si el dominio contiene al menos dos componentes e incluye una mayúscula. Esto ignora las protecciones de sufijos públicos y podría permitir que un sitio web malicioso configure cookies para dominios que no le pertenecen, lo que podría provocar problemas de integridad como la fijación de sesiones."
