What to do
Workaround: Restrict network access to the App-Services port (8000) to trusted networks. Configure a reverse proxy or web application firewall to reject malformed paths, including paths containing encoded path traversal sequences or multiple leading slashes. Users should avoid opening untrusted links while authenticated to Query Console.
