GHSA-hqwm-7x7x-8379 DevSpace UI Server WebSocket CheckOrigin does not validate source

• Go github.com/loft-sh/devspace: >= 6.3.20, < 6.3.21 → fixed in 6.3.21

Description 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 allows an attacker to access: • `/api/logs` to stream real-time pod logs • `/api/enter` to open an interactive shell inside the running pod • `/api/command` to execute pre-defined pipeline commands Patches Versions 6.3.21 and above are patched. Resources gorilla/websocket CheckOrigin documentation Installation Options Devspace is no longer publishing to NPM or Yarn, please continue to use our other installation methods to get updates in the future, including this patch.
