Summary
OpenShell Mirror Sync: Sandbox Escape via Unrestricted File Sync + Symlink Traversal
Current Maintainer Triage
- Status: narrow
- Normalized severity: high
- Assessment: v2026.3.28 still has the mirror-boundary bug because shipped c02ee8 only excluded hooks while unreleased 3b9dab is the first full symlink-free upload and download hardening.
