Copilot CLI 1.0.81 forces sandbox, ignoring local disable config
dfederm · ghdev · 2026-08-19
GitHub Copilot CLI v1.0.81-1 introduces a regression where it enforces sandboxing despite the user setting sandbox.enabled: false. When the server-managed policy is temporarily undetermined, a fail-closed state overrides local configurations, forcing shell, local MCP, and LSP processes into Windows MXC. Since MXC fails to initialize on the host, tools encounter a BaseContainer is unavailable error, and the session does not recover even after policy resolution. The issue is absent in v1.0.80-1.
