[BUG] dangerouslyDisableSandbox executed without user approval after prior rejection
Resolved 💬 3 comments Opened Mar 23, 2026 by bzj55pnkxy-droid Closed Mar 24, 2026
Preflight Checklist
- [x] I have searched existing issues and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code
What's Wrong?
I've added UV to project, and needed to update my settings.json config. Claude asked for permission to disable sandbox to run UV. I then added UV to auto-allow, rejected the tool call and asked it to retry running UV. It instead, somehow without my permission, ran it outside of the sandbox.
What Should Happen?
It should have ran UV in the sandbox.
