DevSpace through 6.3.21 Path Traversal via tar extraction

DevSpace through 6.3.21 fails to reject parent-directory segments in tar entry names from the in-pod sync stream. Attackers operating a malicious container can stream tar entries with traversal sequences to write arbitrary files on the developer workstation, enabling code execution.
