iTerm2 author here. This could be used as a link in an exploit chain but by itself the claim in the title is massively overblown. I’m on a family vacation but I’ll release a fix when I get back.
Disclosure: I didn't discover the vulnerability. I wrote the blog post.
Thanks for releasing a fix!
It was surprising that there wasn't an official release, even though the bug impacts otherwise routine, harmless workflows. The patch itself [1] framed the issue as "hypothetical," so the goal of the blog post was to demonstrate that it is not. I'm glad that you've agreed to release a fix.
