Summary

DevSpace is a developer tool for cloud-native development with Kubernetes. In versions prior to 6.3.21, the DevSpace UI server accepted WebSocket connections from all origins, exposing several endpoints to attack.

Original NVD description (English 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.
