Doc Text:
A flaw was found in Kitty, a cross-platform GPU based terminal. This vulnerability allows an attacker to achieve arbitrary code execution by chaining specific escape sequences (`@kitty-echo` and `@kitty-ssh`) when a user displays untrusted terminal data. These sequences write unauthenticated data to the child shell's input, enabling the execution of attacker-controlled commands. This could lead to a complete compromise of the user's system.

Description OSIDB Bzimport 2026-08-10 21:21:37 UTC 
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.
