Weblogic-Tracing exposes user-password while using LOGON Built-in

We are using Forms & Reports with Fusion Middleware 12.2.1.4 and Oracle Database 19c. When using Enterprise-Manager to trace usersessions and tracing the events 96 and 194, the used credentials for the LOGON Built-in are visible in the trace-files, including the password.

Is there a way to prevent this in plsql-Code inside the form at runtime?

SET_FORMS_TRACE Built-in and SET_FORMS_TRACE_EVENT Built-in seem to be overridden by Enterprise-Manager-Tracing.

If not, is there a way to see at runtime inside the form, if tracing is active, maybe even the traced events?
