DescriptionGitHub Advisory

Ghostty is a cross-platform terminal emulator. Ghostty allows control characters such as 0x03 (Ctrl+C) in pasted and dropped text. These can be used to execute arbitrary commands in some shell environments. This attack requires an attacker to convince the user to copy and paste or drag and drop malicious text. The attack requires user interaction to be triggered, but the dangerous characters are invisible in most GUI environments so it isn't trivially detected, especially if the string contents are complex. Fixed in Ghostty v1.3.0.

AnalysisAI

Ghostty terminal emulator allows control characters embedded in pasted or drag-and-dropped text to execute arbitrary commands in certain shell environments, requiring only user interaction to trigger. An attacker can craft malicious text with invisible control sequences that, when copied/pasted by a user, execute unintended commands with the user's privileges. No patch is currently available for this vulnerability.
