sourcerequest bodydocker cpThe 'docker cp' command (and 'sbx cp' in Docker Sandboxes) is vulnerable to a TOCTOU race condition and improper symbolic link handling during tar extraction. An attacker can use a malicious container to induce the Docker CLI to create or overwrite arbitrary files on the host filesystem by providing a tar archive containing absolute symbolic links.CWE-59
