Possible Critical Security Issue

Hello! I was performing a security review of gstack before allowing our dev teams to use this project, and I believe I have found a critical vulnerability. Full disclosure: Anthropic's Opus 4.7 was used to identify the issue. I don't want to waste anyone's time, so I want to make sure you know that first and foremost. If you would like to know the details, I'd love to share the findings as I have reason to believe this is a legitimate finding. Let me know if you would like me to responsibly disclose this. Also: I'm a human, even though I used AI to find this. Thanks in advance! (And there are other lower findings, happy to share the whole AI generated report, but I think the critical issue is most pressing.)

The issue contains only a high-level security claim and does not name any files, tests, entry points, reproduction steps, or affected behavior. First obtain the promised vulnerability details and determine whether the finding can be reproduced; the work is complete only when the scope, impact, and remediation are documented.
