alt Hacker Newsthe point is tmux is being used by many developers working in high value targets to automate long running unsupervised agent tasks. you don't need the user to execute code, you need _their agent_ to stumble on the wrong search result or github repo and it wont be noticed for hours that they loaded a persistent threat into your environment.
That seems even harder to do because an agent wouldnt be output text verbatim, which means you cant make use of a rendering bug (eg parsing escape codes).
So you’re back to depending on the agent to execute code locally. at which point you’ve already compromised the system so don’t need a tmux bug.
I’ve spent a lot of time in tmux. Including writing a frontend for it. So I’m probably more familiar than most. And I hear a lot of people say tmux (specifically) is a vulnerability because it’s written in C. But I struggle to see how it’s any more of a vulnerability than (for example) coreutils. Or any other piece of software for that matter.
