Summary

Docker Sandboxes guest can write arbitrary macOS host files via a symlink in the virtio-fs stored-path fallback

Details

On macOS, the virtio-fs host server used by Docker Sandboxes improperly follows symlinks when reopening an unlinked file from a stored path. A malicious guest can replace a parent directory with a symlink, escape the shared workspace, and read or modify arbitrary host files as the VMM user, potentially achieving host code execution.
