      The error bellow was solved in this PR https://github.com/openshift/hypershift/pull/4723, but we can do a better sanitisation of the IgnitionServer payload. This is the suggestion from Alberto in Slack: https://redhat-internal.slack.com/archives/G01QS0P2F6W/p1726257008913779?thread_ts=1726241321.475839&cid=G01QS0P2F6W

      ✗ [High] Cross-site Scripting (XSS) 
  Path: ignition-server/cmd/start.go, line 250 
  Info: Unsanitized input from an HTTP header flows into Write, where it is used to render an HTML page returned to the user. This may result in a Reflected Cross-Site Scripting attack (XSS).
