Dear Forum,

I am a new member here, but I use Singular with lots of joy since last year. I recently created SingularWebService ( to make it possible to run Singular commands remotely via HTTP, primarily for using it with GeoGebra (

Today I learned that the
command may be a security hole in SingularWS. Thus I added the
command line option at to prevent entering arbitrary shell command remotely. (SingularWebService is an anonymous service.)

If my change is acceptable for the developers, I would be happy if you could merge this enhancement to the official version.

Thank you and best regards,
