      "value": "Kitty is a cross-platform GPU based terminal. Prior to 0.48.2, the @kitty-echo and @kitty-ssh DCS handlers in kitty/window.py write unauthenticated data to the child shell's stdin, where handle_remote_echo accepts printable shell command characters and handle_remote_ssh calls get_ssh_data in kittens/ssh/utils.py, which emits a newline; chaining the handlers can execute attacker-controlled commands when a user displays untrusted terminal data. This issue is fixed in version 0.48.2."

      "value": "Kitty es un terminal multiplataforma basado en GPU. Antes de la versión 0.48.2, los manejadores DCS @kitty-echo y @kitty-ssh en kitty/window.py escriben datos no autenticados a la entrada estándar (stdin) del shell hijo, donde handle_remote_echo acepta caracteres de comando de shell imprimibles y handle_remote_ssh llama a get_ssh_data en kittens/ssh/utils.py, que emite un salto de línea; encadenar los manejadores puede ejecutar comandos controlados por el atacante cuando un usuario muestra datos de terminal no confiables. Este problema está solucionado en la versión 0.48.2."
