CVE-2026-72913
HighCVSS 7.3Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
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.
Risk Assessment
Risk of arbitrary command execution in the user's terminal, potentially leading to system compromise if the user displays untrusted data.
Recommendation
Upgrade Kitty to version 0.48.2 or later to fix the vulnerability. Avoid displaying untrusted terminal data.
