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.

DevSpace UI Server WebSocket CheckOrigin does not validate source

DevSpace is a client-only developer tool for cloud-native development with Kubernetes. Prior to 6.3.21, DevSpace's UI server WebSocket accepts connections from all origins by default, and therefore several endpoints are exposed via this WebSocket. When a developer runs the DevSpace UI and at the same time uses a browser to access the internet, a malicious website they visit can use their browser to establish a cross-origin WebSocket connection to ws://127.0.0.1:8090. This vulnerability is fixed in 6.3.21.
