Copilot CLI 1.0.83-5 cuts sandboxed commands off from localhost, and it will break your test suite
Published 2026-09-04 at 03:01 UTC, this release stops sandboxed commands on macOS and Linux reaching services running on your machine. On macOS it also blocks a server the command itself starts on 127.0.0.1, so any test suite that binds a local port now fails inside the sandbox until you turn on Allow local network in `/sandbox`. Linux sandboxing additionally now requires slirp4netns, nsenter, iptables, ip6tables, iptables-restore and ip6tables-restore on PATH, or sandboxed commands fail to launch at all.
