Command execution via unsanitized pasted control characters
Published Mar 9, 2026 · Updated Mar 9, 2026
Command injection in Ghostty 1.2.3 and earlier allows remote attackers to execute arbitrary shell commands through pasted or dropped text. The src/input/paste.zig encode path forwards PTY-sensitive control bytes, including Ctrl+C, instead of replacing them before insertion. Exploitation requires a user to paste or drop attacker-controlled text into a Bash or Zsh session, where normally invisible bytes can interrupt input and execute subsequent commands.
