  unauthorized update, insert or delete access to some of the accessible data.

  Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through
  a web service which supplies data to the APIs. This vulnerability also applies to Java
  deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java
  applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on
  the Java sandbox for security.");
