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 commandsVersions 6.3.21 and above are patched.
