Description OSIDB Bzimport 2026-06-12 21:02:13 UTC 
Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.3, kitty's OSC 21 (color-control) query reply reflects attacker-controlled bytes, including newlines, into the shell's input without sanitization. Version 0.47.3 fixes the issue.
