NewCVE-2026-72913 (opens in a new tab)How to fix?
There is no fixed version for Echo:latest kitty.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kitty package and not the kitty package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
