Don't worry about it further -- I'll fix the parsing bug that you
found sometime this week. If you find any further bugs anywhere in
cloud.sagemath.com, please don't hesitate to report them! Than

Thanks. Where all of this I'd implemented ?

Indeed there are small security problems and big ones. The use of eval or
