An issue was discovered in iTerm2 3.5.x before 3.5.2. Unfiltered use of an escape sequence to report a window title, in combination with the built-in tmux integration feature (enabled by default), allows an attacker to inject arbitrary code into the terminal, a different vulnerability than CVE-2024-38395.
