Fable AI Risks Jailbreak for Zero-Day Exploits in Open Source Code

Original post

You ask Fable to “fix vulnerabilities” in your codebase with tests, and your codebase is actually some open source software, then you just jailbroke it to give you zero day attacks.

If unrestricted Mythos is dangerous how is this ok?

@simonw Asking to fix it and write tests to make sure makes the vulnerability visible to the user. So just by doing this on OSS software you can mine zero days.

If this really is the "jailbreak" that got Fable shut down I'm deeply unimpressed
