Déjà vu: Ghostly CVEs in my terminal title


xploring a security bug in Ghostty that is eerily familiar. As I've spoken and written about all modern terminals are actually "emulating" something dating from the 1970s.

One aspect of this attack that isn't immediately clear is the input goes via your terminal, so it's like you typed it, even if you're connected to a remote system via SSH. If for some reason you can't upgrade, the advisory has a workaround where a fixed title will not let an attacker control the value reported back. This isn't as complete as the Zsh mitigation, as you could still be blindly tricked to press Enter and run an unexpected command, but it works for this particular issue in Ghostty.
